# HomeAssistant MQTT Components Binding

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

|-----------------------|---------------|------------------------------------|
| Object                | Thing         | homeassistant/../../object         |
| Component+Node        | Channel Group | homeassistant/component/node/object|
| -> Component Features | Channel       | state/topic/defined/in/comp/config |
