can’t see anything wrong with your code.
have you sync your devices in GA after the change? Whenever you do changes to your config, you need to ask GA to “sync my devices” so it gets the latest setup…
I can’t remember as it’s been a while since I set up mine, but you may need to create the rooms in GA first, else you’ll try and assign a device to a room that does not exist…
The room exists in my GA and yes I did sync up device after setting up.
Problem is the “Name” works, as you can see “pom pom” isn’t a normal name, I tried changing it and it works.
