2 VTHERM with the same external temperature sensor : one is outdated !

[ChrysMa]

Hello,
I have 2 VTHERM (for 2 bathrooms) they share the same external temperature sensor (from a zigbee sensor through Z2M) one climate is reporting the last update datetime correctly the other... is wrong ... then deactivates the VTHERM.
What can I do to have it back all the time?
Those VTherm are simple climate over switch ones...

Hello,

I think you have to check the configuration. Can you give the VTHerm attributes ? (Development Tools / State)

[ChrysMa]

Sure ;-)
And despite what you can read now (the last ext temp is reporting exact same date as I'm faking the date...) see the reported sensor temp. Should be exactly the same, because I now set an automation that update all sensors temperatures every 5 minutes... I got the same problem for many VTHERM (not just those 2 ones)
