 # Changelog
 
-#### :warning: This add-on is considered to be obsolete/retired in favor of the much more advanced third-party [RaspberryMatic CCU](https://github.com/jens-maus/RaspberryMatic/tree/master/home-assistant-addon) add-on for running a HomeMatic/homematicIP smart home central within HomeAssistant.

[RaspberryMatic Documentation](https://github.com/jens-maus/RaspberryMatic/wiki/Installation-HomeAssistant)) :warning:
