Temperature sensor state turns into x °C

Hi,
I suddenly get some weird state readings on some of my temperature sensors. The state is x °C, but the the history graph shows correct values:

I am using Z2M for connection and the correct status is forwarded to Home Assistant:

It is also really odd that that I’m using the temperature sensors in my fridges and freezer and they’re showing state correctly.

I really don’t know we’re to look, so any good ideas would be appreciated.

You have accidentally chosen roman numerals. :smiley: :smiley: :smiley:

Try to check the MQTT broker with MQTT explorer.
Also check the state in developer tools.
You need to figure out where the error is and where it is not.

Sounds strange, as it should be XXI or something to reflect 21 degrees celcius. All the affected sensors shows x despite different values

I tested changing the unit of measurement and both Kelvin and Fahrenheit is showing the right state:


Only Celcius is showing the odd x °C
