/*********************************************************************************************\
* Rules based heavily on ESP Easy implementation
*
* Inspiration: https://github.com/letscontrolit/ESPEasy
*
* Add rules using the following, case insensitive, format:
* on <trigger1> do <commands> endon on <trigger2> do <commands> endon ..
*
* Examples:
* on System#Boot do Color 001000 endon
* on INA219#Current>0.100 do Dimmer 10 endon
* on INA219#Current>0.100 do Backlog Dimmer 10;Color 10,0,0 endon
* on INA219#Current>0.100 do Backlog Dimmer 10;Color 100000 endon on System#Boot do color 001000 endon
* on ds18b20#temperature>23 do power off endon on ds18b20#temperature<22 do power on endon
* on mqtt#connected do color 000010 endon
* on mqtt#disconnected do color 00100C endon
* on time#initialized do color 001000 endon
* on time#initialized>120 do color 001000 endon
* on time#set do color 001008 endon
* on clock#timer=3 do color 080800 endon
* on rules#timer=1 do color 080800 endon
* on mqtt#connected do color 000010 endon on mqtt#disconnected do color 001010 endon on time#initialized do color 001000 endon on time#set do backlog color 000810;ruletimer1 10 endon on rules#timer=1 do color 080800 endon
* on event#anyname do color 100000 endon
* on event#anyname do color %value% endon
* on power1#state=1 do color 001000 endon
* on button1#state do publish cmnd/ring2/power %value% endon on button2#state do publish cmnd/strip1/power %value% endon
* on switch1#state do power2 %value% endon
* on analog#a0div10 do publish cmnd/ring2/dimmer %value% endon
*
* Notes:
* Spaces after <on>, around <do> and before <endon> are mandatory
* System#Boot is initiated after MQTT is connected due to command handling preparation
* Control rule triggering with command:
* Rule 0 = Rules disabled (Off)
* Rule 1 = Rules enabled (On)
* Rule 2 = Toggle rules state
* Rule 4 = Perform commands as long as trigger is met (Once OFF)
* Rule 5 = Perform commands once until trigger is not met (Once ON)
* Rule 6 = Toggle Once state
* Execute an event like:
* Event anyname=001000
* Set a RuleTimer to 100 seconds like:
* RuleTimer2 100
