Domoticz MQTT Discovery plugin with Sonoff-Tasmota extensions

Domoticz Python plugin which implements support for Home-Assistant style MQTT discovery.

Features:

• Switch and dimmer devices will be automatically found and added to Domoticz device database
• State in Domoticz in synchronized with device state (unlike if using Domoitcz MQTT + "Dummy hardware")
• Note: Sensors are not yet supported
• The plugin has some special adaptations for the Tasmota ESP8266 firmware.

Prerequisites (general):

• Working Domoticz installation
• Working MQTT server

Prerequisites (Sonoff or other ESP8266 devices with tasmota firmware):

• Sonoff devices must be flashed with 5.11.1c or newer (must include support for home-assistant style MQTT discovery)
• Sonoff devices must have Home Assistant Discovery (option 19) set to 1 (setoption19 1)
• Sonoff devices must be connected to MQTT server, and must have individual topics (by default all devices topic will be set to sonoff, this will not work)
• Sonoff fulltopic should be reasonable, for example "tasmota/%topic%/%prefix%/"

Instructions:

• Clone this project into Domoticz 'plugins' folder
• Restart Domoticz
• Create hardware of type "MQTT Discovery"
  • Set MQTT IP and port
  • Set "Debug" to "Verbose" for debug log
• Domoticz should now detect any device running Tasmota firmware
