• Prerequisites
• Domoticz MQTT and Virtual Sensor
• Domoticz virtual switch
• Tasmota
• Usage

Sonoff supports Domoticz MQTT 'out of the box' for both relays and sensors.

Find below the procedure to configure Domoticz and Tasmota.

Prerequisites

The following servers should be made available:

• You have installed/access to a MQTT broker server and made contact with your sonoff
• You have installed Domoticz

Domoticz MQTT and Virtual Sensor

If not already done configure Domoticz MQTT and Virtual Sensor hardware.

• On the hardware page add Type MQTT Client Gateway with LAN interface
  1. Give it a name
  2. Configure the interface with access to your MQTT server (Remote Address, Port, Username and Password)
  3. Set the Public Topic to flat (which seems to relate to out in the select field)
• On the hardware page add Type Dummy (used for virtual switches)
  1. Give it a name

Domoticz virtual switch

Make a new virtual switch and remeber its Idx number.

1. Make a new virtual switch to be used with Sonoff by clicking Create Virtual Sensors
   1. Give it a name
   2. Select Sensor Type Switch
2. On the Devices page find the new switch by it's name
   1. Remember it's Idx number

Tasmota

Sonoff provides different ways to configure Domoticz parameters. Choose the method you prefer:

[The sections below don't look like they are needed any longer. The in topic and out topic entry areas don't appear to be in the DOMOTICZ config section for the Sonoffs running Tasmota firmware - at least they are not there in mine and mine is working 17/03/2018]

• Use the webinterface and select Configuration - Configure Domoticz
  1. Set In topic to domoticz/in as hardcoded in Domoticz
  2. Set Out topic to domoticz/out as hardcoded in Domoticz
  3. Configure Idx 1 to the value read in step 2.i
• Use MQTT and execute commands (if necessary, replace sonoff with unique topic you configured in Initital Configuration, see point 5 there):
  1. cmnd/tasmota/DomoticzInTopic with payload domoticz/in as hardcoded in Domoticz
  2. cmnd/tasmota/DomoticzOutTopic with payload domoticz/out as hardcoded in Domoticz
  3. cmnd/tasmota/DomoticzIdx1 with payload value read in step 2.i
• Use the serial interface and execute commands:
  1. DomoticzInTopic with domoticz/in as hardcoded in Domoticz
  2. DomoticzOutTopic with domoticz/out as hardcoded in Domoticz
  3. DomoticzIdx1 with the value read in step 2.i

Usage

That's it! You can now switch Sonoff from the Domoticz user interface.

• On the Switches page scroll down and find your Switch as configured in step 1
  • Toggle the light bulb; Sonoff should respond
