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.
