So it was pointed out to me by @MichaelS that he couldn’t assign devices to rooms unless the device had a Hubset also. Since the Hubis Optional I find this counter intuitive. There’s not even an error message!
I looked and all of my rooms are empty as none of them had a Hub. When I setup my system they were all showing so this is definitely a new issue. Going into the IDE I can see the devices assigned to the rooms but it won’t show on my phone until I set the Hub.
As emailing support has resulted in copy-paste answers after waiting days I’m bringing this up here. Perhaps our community advocates can get this to the right people.
Edit: Replace Location with Hub. Dangit!
