Hi there!
I have a garage opener from the german manufacturer Hörmann. This device is connected to my Apple Homekit system. Unfortunately, HA is not recognizing this device. Maybe, when I reset the device and make a search, the device could be listed in HA. After that, I could pair it with Homekit again.
But for now, is it also possible to have access to devices listed in Homekit, but not found by HA? The Eve app for example has this possibility.
