Problem after HA update

Configuration Zigbee

Hi all, I have 10 Radiator Thermostat from Bosch connected directly via a dongle Sonoff ad HA.With the last update of this month of HA the climate show only HVAC mode OFF. :frowning: What can I do??

Same here after the update for me it was a ZHA/Zigbee quirk issue — restarting ZHA and re-pairing one thermostat fixed the HVAC modes. Also worth checking the device page for hvac_modes changes or rolling back the update if needed.

Same here. I have 7 of these Bosch thermostats, and after updating to version 2026.2 the heating mode is gone.

I will try to re-pair one of them, but that’s really weird and should not be necessary after just an update.

I try to re pair a couple and they get back to work properly. What a scare :slight_smile:

Actually it’s a caos.
After the reconnected the devices the climate show again the
HVAC modes however behaviors are not correct. Some entities do non update. One climate show a wrong current temperature…Already spending time to debug

How is going on? Here I had to downgrade HA back to the preview Version…

Is there any update on this issue?

It feels like nothing is happening at all. This was working fine before, and a Home Assistant update broke it — and now it just seems to be left in that state.

That’s quite frustrating, to be honest. Is anyone currently working on a fix or is there any progress?
