I like the new Room functionality and I know that this feature is "foundational", so maybe these are known issues. I added several rooms, which is pretty intuitive in the web UI.
I added all of my locks to one of the rooms. I'm not seeing them in the mobile app, however. Contact sensors seem to be missing as well. Everything else I added (dimmers, switches, my siren, etc. seem to be displayed and functional. It's a nice start and I think it's going to be very useful. BTW, this is on the Android mobile app.
Is a Shelly relay a switch? I can add the parent device to a room but cannot add the child device (not available)
In the app I cannot see the parent device (makes sence)
It looks as if you can add the child devices from the device page directly.
The only issue is (and it is a big one), if you go into the Room configuration, and then save, the child devices will get removed, and you will have to add them again.
