What would you like to know? The workaround via Home Assistant, or what exactly?
There are already several topics about how to integrate Home Assistant with Homey. For example this one: [TUTORIAL][PRO] How to integrate Home Assistant with Homey
You can find also a lot of tutorials and infos about the integration of Homematic with HA in the web. This is the “official” one: Homematic - Home Assistant
I won’t go into this any further in this topic, as this topic is about the Homey Homematic app for Homey. But you can search the forum or ask about it in a separate topic.
