Hallo,
maybe I get it wrong as a beginner, but is it not possible to integrate Homematic as a third party in Home Assistant so that both can run side by side on a Raspberry and you can control or read values in Homematic from Home Assistant? I installed Homematic on the same Raspberry as a third party. However, I don’t even get the selection to teach in in the teach-in dialog. The selection of some menu items in Homematic also leads to the picture becoming gray and nothing more happens.
It’s not like I haven’t had any experience here. I run a Raspberry with RaspberryMatic and one with Home Assistant. But now I want to make 1 out of 2 Raspberries.
