Configuration Z-Wave

Hello
I updated firmware on my thermostats, Heatit Z-TRM3, from 4.0.33 to 4.0.34.
After update i lost connection. Any idea what went wrong? Someone with the same issue?

Same issue here.

After firmware update HA does interview of the device, which fails and device becomes unavailable. Tried with three different thermostats and same result.

Revived one by excluding it from network, then factory reset and re-add to network. Figuring out now if there’s a less destructive remedy.

Yes, had the same issue. Rolled Back to 4.0.33 while waiting for this to be fixed.
