Use long press action on a switch

NOTE: This example is for GPIOs defined as switches not buttons

Activate long press action with Switchmode 5 and shorten long press time to 2 seconds (Setoption32 20).

Long pressing on switch1 sends POWER 2 (toggle action) command to the tasmota02 device

Backlog SwitchMode 5; SetOption32 20
Rule on switch1#state=3 do publish cmnd/tasmota02/POWER 2 endon
Rule 1

Notice we use Rule which edits Rule1 rule set. They can be used interchangeably.

Execute any MQTT message when a button is pressed

When a button is pressed the user has the possibility to send a MQTT message based on FullTopic and ButtonTopic. This MQTT message is going to be received by the MQTT Broker and if there is any other device(s) subscripted to that Topic, it will receive also that message. So this approach can be used for sending messages/commands to MQTT Broker to Home Automation System, and/or sending messages/commands to MQTT Broker to other device(s).

A problem with this solution is that on a Sonoff 4CH all four buttons will be sending the same MQTT topic using only a different Power index number like cmnd/ButtonTopic/power3 toggle.

By using a rule a single button can now send any MQTT message allowing much more flexibility.

Hardware

Sonoff 4CH

Software

Tasmota compiled with #define USE_RULES
Disable ButtonTopic as it overrides rules for buttons: ButtonTopic 0

Rule

Rule1
  on button1#state do publish cmnd/ring2/power %value% endon
  on button2#state do publish cmnd/strip1/power %value% endon

(You will likely need to enable this rule if it's the first time you've used them) "Rule1 on".

Result

When button 1 is pressed the rule kicks in and sends a MQTT message substituting variable %value% with the button state like cmnd/ring2/power 2. When button 2 is pressed a MQTT message like cmnd/strip1/power 2 will be sent.

Execute several commands when a Timer expires

The default Timer1..16 functionality allows for controlling one output to either off, on, toggle or blink. When rules are enabled the blink option will be replaced by rule functionality allowing much more flexibility.

Hardware

Sonoff 4CH

Software

Tasmota compiled with #define USE_RULES
Configure timer5 for rule execution when activated:
timer5 {"Arm":1,"Mode":0,"Time":"16:00","Days":"1111111","Repeat":1,"Action":3}
Rule
Rule1 on clock#Timer=5 do backlog power2 on;power1 off;power3 2 endon

Result

When the timer expires the rule kicks in and set Power1 to OFF, Power2 to ON and Toggles Power3

If you want to have blink functionality define a rule like on clock#Timer=5 do power 3 endon

Usage of one-shot (once)

The rule command once option provides the possibility to trigger only once on a slow change while the change is still within the bounds of the test.

Rule

on ENERGY#Current>0.100 do publish tool/tablesaw/power 1 endon
on ENERGY#Current<0.100 do publish tool/tablesaw/power 0 endon

This creates a rule to publish MQTT commands whenever a Sonoff POW has current passing through it. Used as is, it will publish MQTT commands repeatedly, over and over, while current is >0.100 ... but, executing another command:

Rule 5

Now the MQTT message will be sent once, and only once, while the condition is met. This is perfect for thermostat on/off depending on temperature, bathroom extractor fan on/off depending on humidity, workshop dust collector on/off depending on whether some dust-producing machine is running.

It meets the 'hard thermostat' requests that have been common.

Use of variables and tele-

Using variables allows for storing sensor results to be used in composing a single HA message like used with Domoticz. To prevent flooding Domoticz with messages we only want to send a message at TelePeriod time. This is achieved by prefixing the <SensorName> with the label tele-. This example will use a variable storing the temperature to be used together with humidity in one Domoticz MQTT message.

Hardware

Sonoff TH or Wemos D1 mini
AM2301 Temperature and Humidity sensor

Software

Tasmota compiled with #define USE_RULES
Home Automation tool Domoticz configured with a virtual sensor Temp+Hum using Idx 134

Rule

on tele-am2301-12#temperature do var1 %value% endon
on tele-am2301-12#humidity do publish domoticz/in {"idx":134,"svalue":"%var1%;%value%;1"} endon

Result

As a result of the tele- prefix the rules will be checked at TelePeriod time for sensor AM2301-12 Temperature and Humidity. The first rule will use the Temperature stored in %value% and save it in %var1% for future use. The second rule will use the Humidity stored in %value% and the Temperature stored in %var1% to compose a single MQTT message suitable for Domoticz.

Clever Dickies now finally have a way to send Temperatures from multiple DS18B20 to Domoticz.

Use a potentiometer

Connecting a potentiometer to the Analog A0 input and a rule can be used to control the dimmer state of any device.

Hardware

Wemos D1 mini
Potentiometer of 2k2 connected to Gnd, A0 and 3V3
WS2812 LED

Software

Tasmota compiled with #define USE_RULES

Rule

on analog#a0div10 do dimmer %value% endon

Result

Turning the potentiometer the voltage on the analog input will change resulting in a value change of 0 (Off) to 100 for the trigger. Using this value to control the dimmer of the WS2812 will control the brightness of the led(s)

Rule

on analog#a0div10 do publish cmnd/grouplight/dimmer %value% endon

Result

This time all lights configured with GroupTopic grouplight will change their brightness according to the potentiometer position.

NOTE: You might want to execute command SaveData 2 to reduce flash writes ;-)

Setting variables

Demonstrate the use of variables. Make sure to execute commands Rule 4(Disable one-shot detection) first when trying the following example.

Set a variable

rule needed:
on event#setvar1 do var1 %value% endon

command:
event setvar1=1
View a variable

rule needed:
on event#getvar1 do var1 endon

command:
event getvar1

Toggle a variable

rules needed:

on event#togglevar1 do event toggling1=%var1% endon
on event#toggling1<1 do event setvar1=1 endon
on event#toggling1>0 do event setvar1=0 endon
on event#setvar1 do var1 %value% endon

command:
event togglevar1

Show Messages:

rule needed:
on event#message do publish stat/[topic]/log %value% endon

command:
event message=INIT
All event commands can be executed from:

console: event anyname=number mqtt: cmnd/[topic]/event anyname=number

Everything together:

Rule1 
  on event#togglevar1 do event toggling1=%var1% endon 
  on event#toggling1<1 do event setvar1=1 endon 
  on event#toggling1>0 do event setvar1=0 endon 
  on event#setvar1 do var1 %value% endon 
  on event#getvar1 do var1 endon 
  on event#message do publish stat/mqttTopic/log %value% endon

NOTE

Note that the following won't work:
Rule1 on event#setvar1 do backlog var1 %value%; power1 %var1% endon

Well at least not as you probably would expect. The var1 value used by the power1 command will be the value present before the backlog command is executed. This is so, because the rule will replace %var1% BEFORE the backlog commands are put in the backlog command stream.

Control device LEDs with Relays

If a device has more than one relay and LEDs on different GPIOs (not connected to the relay) you need to use rules to display current relay status on LEDs. This example is a 3 gang wall switch. Instead of LEDs you need to assign 3 dummy relays that will be controlled when the real relays are switched to reflect their status.

Backlog ledmask 0x0000; setoption13 1; seriallog 0

rule1 
  on power1#state do power4 %value% endon 
  on power2#state do power5 %value% endon 
  on power3#state do power6 %value% endon

rule1 1

Note: This method doubles the number of flash writes. Link to the device

Thermostat Example

As example, to be used on a Sonoff TH10 with Sensor Si7021

This example turn on and off an output based on the temperature value and the upper set point and the lower set point. It waits until is enabled by pressing the button or by mqtt message 1 to mem1. This value is remembered. So if power cycle occurs, will resume operation. The set point values can be changed on the fly by mqtt or console commands If the Temperature sensor disconnects, the outputs will shutdown until the sensor is back again and will resume operation. When the device is power up, the thermostat also waits until the sensor value to resume operation.

Initial Config:

Available physical button as switch1
Relay1 will be used the controller
Rules must be used to control Relay so the pushbutton must only control switch1 and not directly control the relay - For this we use SwitchMode1 3 as described below and create the necessary rules because the pushbutton control of the relay is only disabled when the rules are in place.

Initial config on console:

SwitchMode1 3 <- Use the switch1 as pushbutton (It will allow us to disable the link between the button and the relay by inserting a rule to dictate what the pushbutton will do - NOTE: Until rules are created the pushbutton will still control the relay!)
Rule1 1 <- turn on rules
Rule1 4 <- turn off one-shot rule
TelePeriod 60 <- check temp every minute
SetOption26 1 <- use power1 on mqtt messages
SetOption0 0 <- dont save relay status on eeprom
PowerOnState 0 <- start all relays off
Mem1 0 <- thermostat status: 0-off 1-enabled - View or set by MQTT cmnd/mqttTopic/mem1
Mem2 25 <- setpoint Temp upper limit - View or set by MQTT cmnd/mqttTopic/mem2
Mem3 23 <- setpoint Temp lower limit - View or set by MQTT cmnd/mqttTopic/mem3
Var1 0 <- thermostat actual status: 1-OK 0-NOT READY - View by MQTT cmnd/mqttTopic/var1

Rules:

On boot start a watchdog timer to check temp sensor connection.
Rule on system#boot do RuleTimer1 70 endon

An available button is configured as switch to set thermostat ON or OFF

Rule1
  on switch1#state do backlog event toggling1=%mem1% endon
  on event#toggling1=0 do mem1 1 endon
  on event#toggling1=1 do mem1 0 endon

Check temp sensor connection. If fails, set to off and turn off thermostat. Also continue checking
on Rules#Timer=1 do backlog var1 0; RuleTimer1 70; power1 0 endon

Resets checking timer if temperature is connected
on tele-SI7021#temperature do backlog var1 1; RuleTimer1 30; event ctrl_ready=1; event temp_demand=%value% endon

Thermostat control - upper limit and lower limit and enabled

on on event#ctrl_ready>%mem1% do var1 0 endon
on event#temp_demand>%mem2% do power1 0 endon
on event#temp_demand<%mem3% do power1 %var1% endon

Thermostat can be turned On by:

pushing button
by command on local console: mem1 1
by command on any other console: publish cmnd/mqttTopic/mem1 1
or MQTT at: cmnd/mqttTopic/mem1 1

Thermostat can be turned Off by:

pushing button
by command on local console: mem1 0
by command on any other console: publish cmnd/mqttTopic/mem1 0
or MQTT at: cmnd/mqttTopic/mem1 0

To get the status:

mem1 <- thermostat status: 0-off 1-enabled - View or set by MQTT cmnd/mqttTopic/mem1
mem2 <- setpoint Temp upper limit - View or set by MQTT cmnd/mqttTopic/mem2
mem3 <- setpoint Temp lower limit - View or set by MQTT cmnd/mqttTopic/mem3
var1 <- thermostat actual status: 1-OK 0-NOT READY - View by MQTT cmnd/mqttTopic/var1

Everything together:

INITIAL CONFIG: (Note: RuleTimer1 must be greater that TelePeriod for expected results)

backlog SwitchMode1 3; Rule 1; Rule 4; TelePeriod 60; SetOption26 1; SetOption0 0; poweronstate 0; mem1 0; mem2 25; mem3 23; var1 0

RULES:

Rule1 
  on system#boot do RuleTimer1 70 endon 
  on Switch1#State do event toggling1=%mem1% endon 
  on event#toggling1=0 do mem1 1 endon 
  on event#toggling1=1 do mem1 0 endon 
  on Rules#Timer=1 do backlog var1 0; RuleTimer1 70; power1 0 endon 
  on tele-SI7021#temperature do backlog var1 1; RuleTimer1 70; event ctrl_ready=1; event temp_demand=%value% endon 
  on event#ctrl_ready>%mem1% do var1 0 endon 
  on event#temp_demand>%mem2% do power1 0 endon 
  on event#temp_demand<%mem3% do power1 %var1% endon

EXAMPLE RULES WITHOUT TEMP SENSOR TO TEST THE THERMOSTAT RULES

Rule1 
  on system#boot do RuleTimer1 70 endon 
  on Switch1#State do event toggling1=%mem1% endon 
  on event#toggling1=0 do mem1 1 endon 
  on event#toggling1=1 do mem1 0 endon 
  on Rules#Timer=1 do backlog var1 0; RuleTimer1 70; power1 0 endon 
  on event#temp do backlog var1 1; RuleTimer1 70; event ctrl_ready=1; event temp_demand=%value% endon 
  on event#ctrl_ready>%mem1% do var1 0 endon 
  on event#temp_demand>%mem2% do power1 0 endon 
  on event#temp_demand<%mem3% do power1 %var1% endon

TESTS:

Push the button1. The thermostat changes to ENABLED (mem1=1)
on console: event temp=20 (now the system receives like a tele message from temperature sensor) and will turn on the relay1 (to heat)
on console: event temp=26 (the thermostat turn off the heater)
on console: event temp=22 (the thermostat turn on the heater)
wait more than a minute without using the event temp and the thermostat will turn off as there is no temperature value (like a sensor error or disconnection)
will resume when using again the event temp
console mem1 0, DISABLED, console mem1 1, ENABLED

TIMERS:

With the above the timers can be used to control mem1 and add a schedule to when the thermostat will be enabled
Rule2 on Clock#Timer=1 do mem1 1 endon on Clock#Timer=2 do mem1 0 endon

Solar heater control

In a swimming pool, a filter pump and a solar panel is installed. When the sun is shining, the pump should push water through the solar panel, to heat the pool. When it's night or cloudy, the pump should be off, to avoid cooling the pool water through the solar panel. The pump is controlled by a Sonoff TH10 with 2x DS18B20 sensors connected.

3 rules:

Pump should start when solar panel is more than 2 deg warmer than the pool water
Pump should stop when solar panel is less than 1 deg warmer than the pool water
Pump should not start if the solar panel is below 25 deg Celsius.

t1: pool temp
t2: panel temp
var1: in valid panel temp range?
var2: off threshold temp for panel
var3: on threshold temp for panel
mem3: lowest valid panel temp

mem3 25

rule1
  on DS18B20-1#temperature do
    event t1=%value%
  endon
  on DS18B20-2#temperature do
    event t2=%value%
  endon
  on event#t2>%mem3% do 
    var1 1;
  endon
  on event#t2<=%mem3% do 
    var1 0;
  endon
  on event#t1 do 
    backlog
    var2 %value%;
    add2 1;
  endon
  on event#t1 do 
    backlog
    var3 %value%;
    add3 2;
  endon
  on event#t2>%var3% do
    power1 %var1%;
  endon
  on event#t2<%var2% do
    power1 0;
  endon

rule1 1

To test the rule without having the sensors in place, simply enter the events for t1 and t2 in the console:
Backlog event t1=21;event t2=30

And watch the relay turn on and off based on the values.

Please note that this example does not support manual override or handle missing sensor data. Take a look at Thermostat Example for examples.

Energy Saving Smart Switch

Example of a switch controlling a light with a condition of a required amount of lux.

When the switch is on, the light will turn on but only when you have less than 100 lux in that room. While if the switch is off the light will be off.

Rule1
  on switch1#state=1 do var1 100 endon
  on switch1#state=0 do backlog var1 0; power1 off endon
  on APDS9960#Ambient<%var1% do power1 on endon

All together to work as a rule:

Rule 1

Rule1
  on switch1#state=1 do var1 100 endon 
  on switch1#state=0 do backlog var1 0; power1 off endon 
  on APDS9960#Ambient<%var1% do power1 on endon

Time-delayed Auto-off Switch

Rule:

Rule1
  on button1#state do backlog power1 %value%; RuleTimer1 600 endon
  on Rules#Timer=1 do power1 off endon

Result:
on button1#state do backlog power1 %value%;

On Button press the Light will toggle on/off

RuleTimer1 600 endon

Additionally RuleTimer1 will begin to countdown 10 minutes

on Rules#Timer=1 do power1 off endon

After the RuleTimer1 expires the light will be turned off (if you forgot to turn it off)

Time-delay After Switch Off

Rule:

on switch1#state=1 do backlog
  power1 on;
  ruletimer1 0
endon
on switch1#state=0 do
  ruletimer1 300
endon
on rules#timer=1 do
  power1 0
endon

backlog switchmode1 1; rule1 1

Legend:
ruletimer1 300 sets a 5 minute timer. After that time, fan will be switched off. If during the defined 5 minutes (or in general - when timer is counting) you the switch on, the timer will be canceled.

switchmode1 1 sets the switch in follow mode (LOW=off, HIGH=on)
If you have inverted switch (LOW=on, HIGH=off) then use switchmode1 2

Auto-off Motion Sense Switch

Example works fine on a Wemos D1 Mini. Used as night light with motion sensor or as ambient light on floor or kitchen. I connect an LED Strip WS2812 on D1 and the PIR on D2 and a LDR on A0 (voltage divider with 10k ohm resistor)

PIR example: HR-SC501

The Settings are:
18 Generic
D1 WS2812
D2 Switch1
LDR on Wemos A0 (activated in user_config_override.h)

and type the following statements in the Console:

Rules:

SwitchMode1 1

Rule1
  on analog#a0<400 do backlog Rule3 0; Rule2 1 endon
  on analog#a0>500 do backlog Rule2 0; Rule3 1 endon

Rule2
  on switch1#state do backlog power1 1; RuleTimer1 30 endon
  on Rules#Timer=1 do power1 off endon

Rule3
  on switch1#state do power1 off endon

Activate Rule1 with one shot detection
Backlog Rule1 1; Rule1 6

Optional
Backlog Rule2 4; Rule3 4

Result:

on analog#a0>400

disable Rule3 and activate Rule2
on analog#a0>500

disable Rule2 and activate Rule3
Rule2 activates the LEDs for RuleTimer1 30 seconds on each trigger from PIR the RuleTimer start again.
on Rules#Timer=1 do power1 off

The LEDs turn off after the RuleTimer expires
Rule3 is active on daylight and pipe the PIR signal in a power1 off signal. The LEDs stay off.

Controlling Timers Enabled from a Switch

Assuming that your switch is on GPIO00 and configured as Switch1:

SwitchMode1 1

Rule1
  on Switch1#state=1 do Timers 0 endon
  on Switch1#state=0 do Timers 1 endon

Rule1 1

Switchmode1 1 will make Switch1#state be 1 when ON and 0 when OFF

If you don't set Switchmode1 or it is equal 0, it will only have Switch1#state=2 (toggle) and the previous rule will not work.

Toggle a Relay only when holding the button for 2 seconds

The following example is to explain how to catch and use the HOLD feature for buttons.

Behavior: Disable Button1 Short Press and Toggle Relay1 only when holding button1 for 2 Seconds.

Type in the console:

Backlog ButtonTopic 0; SetOption1 1; SetOption32 20

Rule1
  on button1#state=3 do power1 2 endon
  on button1#state=2 do delay endon

Rule1 1

Commands Explanation

ButtonTopic 0 : (default) To not use topics for buttons
SetOption1 1 : Allow only single, double and hold press button actions
SetOption32 20 : Set key hold time from 0.1 to 10 seconds (20 = 2 seconds)
Rule on button1#state=3 do power1 2 endon : When holding the button1 for 2 seconds it will toggle relay 1 (state = 3 means HOLD)
on button1#state=2 do delay endon : Do nothing when short pressing the button1 (state = 2 means TOGGLE)
Rule1 1 : To enable rules

NOTE: There is no state value for "double press" for Buttons. It is designed that double press will toggle the relay. See Control Other Devices for more information.

In the case you do not want the double press feature you can configure your button as switch and also set SwitchMode that fits your use case (such as SwitchMode 5 to make the switch behave like a pushbutton) [SWITCH does not support double press]

Another example but using switch instead of button:

Backlog SwitchTopic1 0; SwitchMode1 5; SetOption32 20

Rule1
  on switch1#state=3 do power1 2 endon
  on switch1#state=2 do delay endon

Rule1 1

Make Sure Light is on at Night

Using Timers, you can set a light to turn on and off to illuminate a street/patio by night. But if the device has no power at the trigger time, then, when it powers up, the light will be off all night. So, as a fail-safe, implement a conditional control to be checked at Tasmota Startup.

Set Timers to turn on your light at Sunset and Turn off at sunrise. Use poweronstate 0 in order to start with lights off when powering up your device. Set the following rules:

Rule1
  on Time#Initialized do backlog event checksunrise=%time%; event checksunset=%time% endon
  on event#checksunset>%sunset% do power1 1 endon
  on event#checksunrise<%sunrise% do power1 1 endon

The previous rules are conditionals that represent the following logic:

IF %time%>%sunset DO power1 1 / IF %time%<%sunrise DO power1 1

Turn On Light Before Dawn and At Dusk

Turn on light at dusk until your nighttime and again in the morning before dawn.

What if the sun sets after your nighttime, as in during the summer? Then the timer will turn off the light at "night", but then the Sunset timer will turn it on again, so it stays on all night.

Rule1
  on Time#Initialized do event chkSun endon
  on Time#Minute=%sunset% do event chkSun endon
  on Time#Minute=%mem2% do event chkSun endon
  on Time#Minute=%sunrise% do event chkSun endon
  on Time#Minute=%mem1% do event chkSun endon

Rule2
  on event#chkSun do backlog var1 0; event chkSunrise=%time%; event chkSunset=%time%; event chkmorn=%time%; event chknight=%time%; event setPower endon
  on event#chkSunrise<%sunrise% do var1 1 endon
  on event#chkSunset>=%sunset% do var1 1 endon
  on event#chkmorn<%mem1% do var1 0 endon
  on event#chknight>=%mem2% do var1 0 endon
  on event#setPower do power1 %var1% endon

Backlog mem1 360; mem2 1350
Backlog Rule1 1; Rule2 1

Explanation:
# When device restarts, calculate if the light should be on or off

Rule1 1

Using Clock Timer to control a Luminance triggered switch (only in mornings)

Background: Tasmota powers a Sonoff Basic attached to a TS-2561 Luminance Sensor. This switch toggles a lamp ON or OFF. The switch should work as below: i) during daytime (sunrise-sunset): ON when it is too dark (<150 lx) and OFF when it gets brighter (>175 lx). ii) during evenings it ignores the sensor and turns on at sunset and turns off after about 5 hours

Approach: Used a combination of Clock Timers and Rule to do this.

Timer 1: Power ON switch at Sunset
Powers on the switch at sunset with an offset of 20 minutes. Repeats every day.

Timer1 {"Arm":1,"Mode":2,"Time":"-00:20","Window":0,"Days":"1111111","Repeat":1,"Output":1,"Action":1}

Timer 2: Power OFF switch at Night.
Turns power OFF at 23.00hrs. Repeats every day.

Timer2 {"Arm":1,"Mode":0,"Time":"23:00","Window":0,"Days":"1111111","Repeat":1,"Output":1,"Action":0}

Timer 3: Trigger Luminance Rule at Sunrise
Start watching the Lux sensor 15 minutes after sunrise.

Timer3 {"Arm":1,"Mode":1,"Time":"00:15","Window":0,"Days":"1111111","Repeat":1,"Output":1,"Action":3}

Rule 1: Main Rule to check Luminance
If Luminance is less than 150lx, power ON. If it goes beyond 175lx, power OFF.

Rule1
  on tele-TSL2561#Illuminance<150 do power1 1 endon
  on tele-TSL2561#Illuminance>175 do power1 0 endon 

Rule1 1

Rule 2: Trigger Rule1 only in the Mornings
This ensures that Rule1 is triggered when Timer3 starts (in the morning) and stops when Timer1 starts (in the evenings).

Rule2
  on Clock#Timer=3 do Rule1 1 endon
  on Clock#Timer=4 do  Rule1 0  endon

Rule2 1

Button with single press, double press, and hold

You can have all 3 actions but only if defining your GPIO as button. In this case the double press will toggle the relay.

There is also an option to swap the actions of the single press and double press.

BUTTON WITH 3 DIFFERENT ACTIONS

As an example: [assuming Button1]

single press: Turn relay 1
double press: send a mqtt message
hold 2 secs: send another mqtt message

Backlog ButtonTopic 0; SetOption1 1; SetOption11 1; SetOption32 20

Rule1
  on button1#state=3 do publish cmnd/topicHOLD/power 2 endon
  on button1#state=2 do publish cmnd/topicDOUBLEPRESS/power 2 endon  

Rule1 1

Another example: [assuming Button1]

single press: send a mqtt message
double press: Turn relay 1
hold 2 secs: send another mqtt message

Backlog ButtonTopic 0; SetOption1 1; SetOption11 0; SetOption32 20  

Rule1
  on button1#state=3 do publish cmnd/topicHOLD/power 2 endon
  on button1#state=2 do publish cmnd/topicSINGLEPRESS/power 2 endon  

Rule1 1

Note: SetOption11 0

SWITCHES WITH 2 DIFFERENT ACTIONS

Switches do not have double press feature

Example: [assuming a connected pushbutton configured as Switch1]

single press: Do nothing
hold 2 secs: Toggle relay 1

Backlog SwitchTopic1 0; SwitchMode1 5; SetOption32 20  

Rule1
  on Switch1#State=3 do Power1 2 endon
  on Switch1#State=2 do Delay endon  

Rule1 1

Perform any action on single/double press (for switches AND buttons)

SwitchMode 5  

Rule1
  on switch1#state==2 do add1 1 endon
  on switch1#state==2 do power1 2 endon
  on var1#state!=0 do backlog delay 6;var1 0 endon
  on var1#state==2 do publish cmnd/othertasmota/POWER toggle endon

Rule1 on

Explanation:

each toggle of the switch triggers first condition and adds 1 to our variable (var1 in the example),
each toggle of the switch toggles the associated relay (Power1 2 - but can do anything else instead, Publish for example)
when var1 changes to non zero, we set it back to 0 but after a Delay (arbitrarily chosen 6 here - 0.6 seconds)
when var1 reaches 2 (i.e. the switch has been toggled twice within the last 0.6 seconds), desired action is triggered (here: Publish to othertasmota)

Result:
Every time you press the switch, your light toggles state (as it should). If you do press the switch twice in a rapid succession (i.e., double-click), you can trigger a different action (e.g., on a remote device).

External switch to enable or disable doorbell relay with HTTP call

When you want to send MQTT messages ( we use domoticz in this example ) and choose when you want the relay on or off, by simply sending HTTP commands to trigger an event.

Initial Config:

PushButton Doorbell
(Sonoff Basic R1) GPIO14 - Switch4 (12)

Connect the Switch to GND and the GPIO on your device. Be sure put a 4.7k resistor between VCC(3.3v) and the GPIO. This prevents ghost switching (capacitor is optional) See: YouTube

Dont forget to change the IDX value

Commands:

Backlog SwitchTopic 0; SwitchMode4 2; SetOption0 0; PowerOnState 0

var1 1

Rule1
  on event#doorbell do var1 %value% endon
  on switch4#state=1 do publish domoticz/in {"idx":11,"nvalue":1} endon
  on switch4#state=1 do power1 %var1% endon
  on switch4#state=0 do publish domoticz/in {"idx":11,"nvalue":0} endon
  on switch4#state=0 do power1 0 endon

Rule1 1

Usage:

Turn off the relay by calling the event using HTTP:
http://<tasmotaIP>/cm?cmnd=event%20doorbell=0

Turn on the relay by calling the event using HTTP:
http://<tasmotaIP>/cm?cmnd=event%20doorbell=1

If your Tasmota device is password protected, which is most common, then use the following HTTP commands instead. Make sure you change <tasmotaUsername> and <tasmotaPassword>

Off:
http://<tasmotaIP>/cm?&user=<tasmotaUsername>&password=<tasmotaPassword>&cmnd=event%20doorbell=0
On:
http://<tasmotaIP>/cm?&user=<tasmotaUsername>&password=<tasmotaPassword>&cmnd=event%20doorbell=1

Force automatic re-connection to MQTT server via SD DNS

In order to search for the MQTT server using SD-DNS service (a.k.a. Bonjour or Zero Network Configuration) the suggested configuration is to leave the MQTT Host field blank.

The standard behavior of Tasmota is

searches for _mqtt._tcp service
resolve that to the proper IP address
connect to it
in case the connection is successful, retain the IP address and use that in the subsequent connections

The above is not proper, though, in case you have a redundant MQTT (e.g., two MQTT server synchronized). In such case, when the active MQTT fails for any reason, the expected behavior is to achieve automatic re-connection to the other MQTT server.

That can be easily configured defining the following rule on the device console:

Rule1 on Mqtt#Disconnected do MqttHost 0 endon
Rule1 1

If the MqttHost field already contains an IP, you have to delete it using the web interface or the following MQTT command:

mosquitto_pub -h mqtt_server.local -t "cmnd/mqttTopic/MqttHost" -m ''

Change distance to percentage

When measuring distance and you have the need to see it in percentage of distance. In the example 100% is everything below 69cm and 0% is everything above 128cm. This is used for showing fill percentage of a wood pellets storage.

Rule1
  on tele-SR04#distance do backlog var1 %value%; event checklimit=%value%; event senddistance endon
  on event#checklimit>128 do var1 128 endon
  on event#checklimit<69 do var1 68 endon
  on event#senddistance do backlog SCALE1 %var1%, 128, 69, 0, 100; event pubdata endon
  on event#pubdata do publish tele/pannrum-temp/SENSOR %var1% endon

Rule1 1

Distinguish Switch1 and Switch2 (without the use of Relay1 and Relay2)

When two (or more) switches are defined as input and you want to distinguish these in the RESULT topic without the use of Relays, then consider the following rules.

SwitchMode1 1 will make Switch1#state to be 1 when ON and 0 when OFF
SwitchMode1 1
SwitchMode2 1 will make Switch2#state to be 1 when ON and 0 when OFF
SwitchMode2 1
Publish json with key POWER1 and value %value%
Rule1 on switch1#state do publish stat/wemos-4/RESULT {"POWER1":"%value%"} endon
Publish json with key POWER2 and value %value%
Rule2 on switch2#state do publish stat/wemos-4/RESULT {"POWER2":"%value%"} endon
Enable Rule1
Rule1 1
Enable Rule2
Rule2 1

Output:

RUL: SWITCH1#STATE performs "publish stat/wemos-4/RESULT {"POWER1":"1"}"
MQT: stat/wemos-4/RESULT = {"POWER1":"1"}
RUL: SWITCH2#STATE performs "publish stat/wemos-4/RESULT {"POWER2":"1"}"
MQT: stat/wemos-4/RESULT = {"POWER2":"1"}
RUL: SWITCH1#STATE performs "publish stat/wemos-4/RESULT {"POWER1":"0"}"
MQT: stat/wemos-4/RESULT = {"POWER1":"0"}
RUL: SWITCH2#STATE performs "publish stat/wemos-4/RESULT {"POWER2":"0"}"
MQT: stat/wemos-4/RESULT = {"POWER2":"0"}
RUL: SWITCH1#STATE performs "publish stat/wemos-4/RESULT {"POWER1":"1"}"
MQT: stat/wemos-4/RESULT = {"POWER1":"1"}
RUL: SWITCH1#STATE performs "publish stat/wemos-4/RESULT {"POWER1":"0"}"
MQT: stat/wemos-4/RESULT = {"POWER1":"0"}

Receiving state of anything that triggers SWITCH more than one time

With analog intercom doorbells you can take out info about ringing from speaker voltage. You can connect GPIO to it via opto-isolator and resistor to take out state. But even with those speaker voltage is dropping so it switches the device multiple times.

MQT: cmnd/doorbell/POWER2 = OFF (retained)
MQT: cmnd/doorbell/POWER2 = ON (retained)
MQT: cmnd/doorbell/POWER2 = OFF (retained)
MQT: cmnd/doorbell/POWER2 = ON (retained)
MQT: cmnd/doorbell/POWER2 = OFF (retained)

To solve it we can use rules.

SwitchTopic 0

Rule1
  on System#Boot var1 0 endon
  on Switch2#State do backlog add1 1; event START endon
  on event#START do event BELL=%var1% endon
  on event#BELL=1.000 do backlog publish cmnd/bell/power on; RuleTimer1 60 endon
  on event#BELL=0 do publish cmnd/bell/power off endon
  on Rules#Timer=1 do backlog var1 0; event BELL=0 endon

Rule1 1

description:

turn off switchtopic as it is necessary to trigger Switch2#state
on system boot set var1 to 0
on switch2 click (person pushing doorbell) - var1 += 1; trigger event START
on START - set event BELL equal to var1
if event#BELL=1 (triggered first time) publish mqtt message ON and trigger RulesTimer1 for 60 seconds
if event#BELL=0 publish mqtt message OFF
on RulesTimer1 - reset var1 to 0, and call event#BELL.
enable rule 1

In this case we have lock for 60 seconds for multiple people calls or to be resistant for speaker voltage drops.

Prevent Wemos D1 mini load overcurrent

As a WS2812 24 led ring draws approximately 24x3x20 mA = 1.44A and the Wemos D1 mini powered from a PC's USB port can only provide up to 0.5A it would be nice to have some kind of mechanism in place to limit the amount of current to the WS2812 LEDring to 0.1A. This is still enough to light all 24 leds up to color 202020.

Hardware

Wemos D1 mini
INA219 I²C sensor
WS2812 LEDring with 24 LEDs powered by the Wemos D1 mini 5V thru the INA219 sensor

Software

Tasmota compiled with #define USE_RULES

Rule

on INA219#Current>0.100 do Backlog Dimmer 10;Color 10,0,0 endon

Result

When a user raises brightness to a level using more than 0.1A the rule kicks in and lowers the current by executing command Dimmer 10 and changes the color to Red with command Color 10,0,0.

Using dummy GPIO to send Serial codes to the MCU

By having a device (an Oil Diffusser) that controls all its features through an MCU and reports the states in serial codes to the ESP8266 I had to create some rules to control it using the Web UI or standard Power commands.

Rule2 
  on power1#state=1 do serialsend5 55AA00060005020400010213 endon 
  on power1#state=0 do serialsend5 55AA00060005020400010011 endon 
  on power2#state=1 do serialsend5 55AA00060005060400010217 endon 
  on power2#state=0 do serialsend5 55AA00060005060400010015 endon

Power1 controls the device, Power2 turn on and off the light on the device.

Another rule was created to issued commands on boot so the serial interface works every time and to control the built in fan using Event triggers and have its state retained in an MQTT message for Home Assistant.

Rule3 
  on system#boot do backlog baudrate 9600; seriallog 2; serialsend5 55aa000300010306 endon 
  on event#high do backlog serialsend5 55AA00060005650400010175; publish2 stat/diffuser/FAN high endon 
  on event#low do backlog serialsend5 55AA00060005650400010074; publish2 stat/diffuser/FAN low endon

Arithmetic commands to be used with VARs

ADD
ADD1 to ADD5: Add a value to VARx
Syntax: ADDx value
Usage: ADD1 15
Result: VAR1 = VAR1 + 15
SUBTRACT
SUB1 to SUB5: Subtract a value from VARx
Syntax: SUBx value
Usage: SUB1 15
Result: VAR1 = VAR1 - 15
MULTIPLY
MULT1 to MULT5: Multiply a value to VARx
Syntax: MULTx value
Usage: MULT1 15
Result: VAR1 = VAR1 * 15
SCALE A VALUE
SCALE1 to SCALE5: Scale a value from a low and high limit to another low and high limit and store it in VARx (directly equivalent to MAP arduino command)

Syntax: SCALEx value, fromLow, fromHigh, toLow, toHigh

where,

value: the number to scale
fromLow: the lower bound of the value’s current range
fromHigh: the upper bound of the value’s current range
toLow: the lower bound of the value’s target range
toHigh: the upper bound of the value’s target range

(omitted values are taken as zero)

Usage: SCALE1 15, 0, 100, 0, 1000
Result: VAR1 = 150

Transmit sensor value only when a delta is reached

Send only when the sensor value changes by a certain amount.

Rule1
  on SI7021#temperature>%var1% do backlog var1 %value%; publish stat/mqttTopic/temp %value%; var2 %value%; add1 2; sub2 2 endon
  on SI7021#temperature<%var2% do backlog var2 %value%; publish stat/mqttTopic/temp %value%; var1 %value%; add1 2; sub2 2 endon

Adjust the value of a sensor and send it by MQTT

This example adds 2 degrees to the measured temperature and then sends that value to an MQTT topic.

Rule1
  on tele-SI7021#temperature do backlog var1 %value%; add1 2; event sendtemp endon
  on event#sendtemp do publish stat/mqttTopic/temp %var1% endon

Switch relays via serial interface

This example switches a connected relays over the software serial on and off.
Write the following rules:

rule1
  on SSerialReceived#Data=on do power1 1 endon
  on SSerialReceived#Data=off do power1 0 endon

receiving on and off results in

MQT: tele/mqttTopic/RESULT = {"SSerialReceived":"on"}
RUL: SSERIALRECEIVED#DATA=ON performs "power1 1"
MQT: stat/mqttTopic/RESULT = {"POWER":"ON"}
MQT: stat/mqttTopic/POWER = ON
MQT: tele/mqttTopic/RESULT = {"SSerialReceived":"off"}
RUL: SSERIALRECEIVED#DATA=OFF performs "power1 0"
MQT: stat/mqttTopic/RESULT = {"POWER":"OFF"}
MQT: stat/mqttTopic/POWER = OFF

Using BREAK to simulate IF..ELSEIF..ELSE..ENDIF

BREAK is an alternative to ENDON. BREAK will stop the execution for the triggers that follow. If a trigger that ends with BREAK fires, then the following triggers of that rule will not be executed. This allows to simulate IF..ELSEIF..ELSE..ENDIF

Example:

IF temp > 85 then
  VAR1 more85
ELSEIF temp > 83 then
  VAR1 more83
ELSEIF temp > 81 then
  VAR1 more81
ELSEIF temp = 81 then
  VAR1 equal81
ELSE
  VAR1 less81
ENDIF

With the actual rules, if we use a set like the following:

Rule1
  on event#temp>85 do VAR1 more85 endon
  on event#temp>83 do VAR1 more83 endon
  on event#temp>81 do VAR1 more81 endon
  on event#temp=81 do VAR1 equal81 endon
  on event#temp<81 do VAR1 less81 endon

This is the output in the console:

CMD: rule
MQT: stat/living/RESULT = {"Rule1":"ON","Once":"ON","StopOnError":"OFF","Free":322,"Rules":"on event#temp>85 do VAR1 more85 endon on event#temp>83 do VAR1 more83 endon on event#temp>81 do VAR1 more81 endon on event#temp=81 do VAR1 equal81 endon on event#temp<81 do VAR1 less81 endon"}
CMD: event temp=10
MQT: stat/living/RESULT = {"Event":"Done"}
RUL: EVENT#TEMP<81 performs "VAR1 less81"
MQT: stat/living/RESULT = {"Var1":"less81"}
CMD: event temp=100
MQT: stat/living/RESULT = {"Event":"Done"}
RUL: EVENT#TEMP>85 performs "VAR1 more85"
MQT: stat/living/RESULT = {"Var1":"more85"}
RUL: EVENT#TEMP>83 performs "VAR1 more83"
MQT: stat/living/RESULT = {"Var1":"more83"}
RUL: EVENT#TEMP>81 performs "VAR1 more81"
MQT: stat/living/RESULT = {"Var1":"more81"}

So, all the triggers where TEMP>100, are firing. With the BREAK statement the rule set can be changed to:

Rule
  on event#temp>85 do VAR1 more85 break
  on event#temp>83 do VAR1 more83 break
  on event#temp>81 do VAR1 more81 endon
  on event#temp=81 do VAR1 equal81 endon
  on event#temp<81 do VAR1 less81 endon

Which will result in the following output:

CMD: rule
RSL: RESULT = {"Rule1":"ON","Once":"OFF","StopOnError":"OFF","Free":321,"Rules":"on event#temp>85 do VAR1 more85 break on event#temp>83 do VAR1 more83 break on event#temp>81 do VAR1 more81 endon on event#temp=81 do VAR1 equal81 endon on event#temp<81 do VAR1 less81 endon"}
CMD: event temp=10
RSL: RESULT = {"Event":"Done"}
RUL: EVENT#TEMP<81 performs "VAR1 less81"
RSL: RESULT = {"Var1":"less81"}
CMD: event temp=100
RSL: RESULT = {"Event":"Done"}
RUL: EVENT#TEMP>85 performs "VAR1 more85"
RSL: RESULT = {"Var1":"more85"}
CMD: event temp=83
RSL: RESULT = {"Event":"Done"}
RUL: EVENT#TEMP>81 performs "VAR1 more81"
RSL: RESULT = {"Var1":"more81"}

Adjust PowerDelta according to current Power values

Power sensor reporting thresholds are set by a percentage change in the Power value by setting PowerDelta. Power changes from 10W to 11W (10%) may not be very interesting. But power changes from 1000W to 1100W (also 10%) could be very important. To avoid getting reports for small changes but ensuring that larger power swings are reported, a rule set can be used to create a gradient threshold based on the absolute power values.

This rule also uses the one-shot feature of rules to avoid reporting of every small change within a threshold window. The rule (a ON/DO/ENDON rule in this the set) will trigger only once when a threshold is crossed.

Backlog PowerDelta 0; Rule1 0; Rule1 5
 
Rule1
  ON ENERGY#Power>=35 DO Backlog PowerDelta 10; Status 8 BREAK 
  ON ENERGY#Power>=15 DO Backlog PowerDelta 25; Status 8 BREAK 
  ON ENERGY#Power>5 DO Backlog PowerDelta 35; Status 8 BREAK 
  ON ENERGY#Power<=5 DO Backlog PowerDelta 100 ENDON

Rule1 1

Which translates to:

Rule Pseudo Code
IF ENERGY#Power>=35  // ENERGY#Power GE 35
  DO Backlog PowerDelta 10; Status 8
ELSE IF ENERGY#Power>=15  // ENERGY#Power GE 15 and LT 35
  DO Backlog PowerDelta 25; Status 8
ELSE IF ENERGY#Power>5  // ENERGY#Power GT 5 and LT 15
  DO Backlog PowerDelta 35; Status 8
ELSE  // ENERGY#Power changed (i.e. LE 5)
  DO PowerDelta 100

IR Forward

Using one IR receiver and one sender (or both extender) you can simply forward signals from one to another using the following rule

rule1 on IRreceived#Data do publish cmnd/irsideboard/irsend {Protocol:NEC,Bits:32,Data:0x%value%} endon

Remote Control Button Multi-press

For example, a remote control with one button to change speed. This rules simulates pressing the button three times to set the receiving device to the third speed setting.

//Specify the rule set
//The <trigger> can be a a condition or an event sent from another device or home automation hub.
//<topic> corresponds to the device transmitting the code (e.g., YTF IR Bridge). This could also be modified to send an RF code from a Sonoff RF Bridge.

Rule1 1

Two-way light switches without MQTT

Two Sonoff T1 3-gang light switches can be used at either end of a room by setting up one the master and the other as the slave. The master performs the switching of the power to the lights, while the slave just asks the master to toggle the power state. The master also turns the slave's relays on and off so that the LED indicators follow the master's state.

Using the WebSend command, the two switches can talk to each other - no need for an MQTT broker. It remains to be seen how reliable this is.

Starting with the slave, the rule to toggle the master is pretty simple:

Rule1
  ON Button1#State DO WebSend [192.168.0.74] POWER1 TOGGLE ENDON
  ON Button2#State DO WebSend [192.168.0.74] POWER2 TOGGLE ENDON
  ON Button3#State DO WebSend [192.168.0.74] POWER3 TOGGLE ENDON

Rule1 1

Note that having a rule for the Button#State disables the power toggling of the slave's relay(s). This is desirable because we want the master to control the slave's relay state(s) according to its own as follows:

Rule1
  ON Power1#state DO WebSend [192.168.0.144] POWER1 %value% ENDON
  ON Power2#state DO WebSend [192.168.0.144] POWER2 %value% ENDON
  ON Power3#state DO WebSend [192.168.0.144] POWER3 %value% ENDON

Rule1 1

Roller shutter push-button toggle

With a two relay device (e.g., Shelly 2.5) configured for a roller shutter, you can also connect push-buttons (configured as switch components in this example) and set them for inverted toggle behavior. Pressing a push-button once makes the roller shutter move in one direction. Pressing it again stops it. These rules each use a variable to remember the shutter state where 0 == Stopped and 1 == Moving.

Backlog SwitchTopic 0; SwitchMode1 4; SwitchMode2 4

Rule1
  ON Switch1#State==1 DO Add1 1 ENDON
  ON Var1#State==0 DO ShutterStop1 ENDON
  ON Var1#State==1 DO ShutterClose1 ENDON
  ON Var1#State>=2 DO Var1 0 ENDON
  ON Shutter1#Close DO Var1 0 ENDON
  ON Switch2#State==1 DO Add2 1 ENDON
  ON Var2#State==0 DO ShutterStop1 ENDON
  ON Var2#State==1 DO ShutterOpen1 ENDON
  ON Var2#State>=2 DO Var2 0 ENDON
  ON Shutter1#Open DO Var2 0 ENDON

Rule1 1
