Read this for Matter users
It’s not apparent, but you CAN get this added via Matter without using the WarmUp app or creating an account with them.
Go through the set up screens on the device. When you get to set up app QR code, tap dismiss. When it asks for a time and date, dismiss that too. Now you’re at the Home Screen. Go to settings. Network. And hopefully the Matter button is available and not greyed out. Use your favorite smart home app to scan the Matter code and your smart phone will set up the WiFi and add the device. If the matter option is greyed out, you’ll have to factory reset. It’s a different screen than the network screen which confusingly has a reset all network connections button that doesn’t perform a factory reset.
I use Home Assistant and this worked for me. Now this thermostat is going to be installed hidden away in a closet never to be touched again. My smart home will handle automating turning on the floor heat and a button on my Zooz scene controller can also control the heat, along with the lights in the room, fan boost etc.
Setting this up I found myself with a greyed out button for Matter. Support wasn’t able to figure out why, the product designer responsible for this UC should be ashamed they didn’t make the setup workflow ask you if you want to setup with Matter or the App. Simply offering both choices in the initial setup would have made this setup a 5 star experience instead of 1 star and several days of frustration.

Horrible user experience
The app barely works and even when it does it’s just plainly horrible to use. When adding new thermostats, you cannot paste the WiFi password 😂 clearly nobody cared or tested the app
Fails pair with device
It crashes on attaching a ne thermostat. Does not have accurate instructions for manual pairing. Does not allow paste of any details in forms, and does not retain partial set up that fails.
Real junk
Im surprised anybody let this be released it’s unusable.
Overly complicated, app won’t connect to my WiFi.
Our contractor put this in and I can’t get it to work. The app won’t connect to my WiFi. I’d give anything to have a simple on/off switch and a dial for heat. I gave it two stars because it makes a nice nightlight for our new bathroom.
