# 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->Addons->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.
