Strange problem with homekit controller + tado radiator thermostats

i’m using ha v2024.10 and now i’m having a strange problem… so

all the the radiator thermostats turn “unavailable” when homekit controller stops to work for whatever reason, ok i use tado as backup integration…

the homekit controller integration is back to work when i restart the haos/or/router/or/bridge, but… at this point all the radiator thermostats turn “on” even if they where “off” and show temp 100°C/humidity 100%… this situation remain until the entities are updated and this could not happen (at least soon), so my water heater could turn on and remain on indefinitely because that behaviour

is this a bug?!

thanks

I have similar weird things with Netatmo connected through Homekit Device. The integration will randomly not load. When it does load after I load it manually, some sensors stay inavailable for quite a while, others report 0 instead of unavailable. Even within one device (indoor climate module) co2 will be 0 and tem/hum nicely set. It will take a long while before the co2 levels read the normal value.

The same for me with tado + homekit integration, but just for one of my tado devices. (HA 2025.2.5).

And looks like others have seen it too 1 Tado device, from HomeKit, keeps losing connection. Other devices have no problem at all. · Issue #102660 · home-assistant/core · GitHub

Examining HA Logbook, I could see the connetion was intermittent. (regularly flipping between “unavailable” and “heat”).
Strangely the Tado app showed far fewer connection problems (by viewing the temperature history graph).

Anyway, the fix for me was to reposition my Tado bridge slightly, for better signal.
Since this, my Logbook has been clean for over 4 days.

Has there been any solutions found for this?

I’ve just moved my heating system control from Hubitat and i use HomeKit Device to integrate Tado Radiator Thermostats V3 directly.

Problem is that they became unavailable. At first i noticed only one of them , the closest to the bridge (2m), then all of them.
