[mqtt] set the proper unit in the state description (#13604) 
So that other pieces of openhab can know what unit it's going to be,
without it having a value yet. Importantly, any necessary conversion
that need to be applied to the other portion of the state description -
min, max, and step.

HomeAssistant MQTT Components Binding

HomeAssistant MQTT Components are recognized as well. The base topic needs to be homeassistant. The mapping is structured like this:

HA MQTT Framework Example MQTT topic
Object Thing homeassistant/../../object
Component+Node Channel Group homeassistant/component/node/object
→ Component Features Channel state/topic/defined/in/comp/config

Requirements

The HomeAssistant MQTT requires two transformations to be installed:

  • JINJA-Transformations
  • JSONPath-Transformations

These can be installed under Settings → Addon → Transformations

Limitations

  • The HomeAssistant Fan Components only support ON/OFF.
  • The HomeAssistant Cover Components only support OPEN/CLOSE/STOP.
  • The HomeAssistant Light Component only supports RGB color changes.
  • The HomeAssistant Climate Components is not yet supported.

Tasmota auto discovery

To activate HomeAssistant discovery support on your Tasmota device you need to do the following:

  • Configuration → MQTT: You must have unique Client name and Topic (should be the default).
  • Configuration → Other: The Device Name will be used to identify the newly found device. And you need to enable MQTT, of course.
  • Console: Enter SetOption19 1.

Your Tasmota device should now show up in your inbox.
