homeassistant

I have this same thermostat and it's been a while since I set it up but I don't remember seeing anything like that. However, with my other 40+ z-wave devices I've definitely seen things like that (especially the unknown manufacturer). Especially if, as an example, power freaks out and I had to redo a bunch of bulbs (thankfully I haven't had to do that in a couple of years).

Here's a smattering of things that I would suggest to try if you haven't already:

Do a reinterview of the node

Reboot z-wave jsui and home assistant

Exclude the thermostat and then factory reset it

Make sure it really is out of z-wave jsui, maybe even after another reboot

Add the thermostat back in and give it plenty of time to be interviewed by the controller

If those things don't work, I would suggest moving z-wave jsui over to being done inside of home assistant, at least for a test just to make sure you can get it working in at least one way.

Good luck!
