Hello,
at first, I have to say, that I just started with HA.
In my dashboard the temperatures are always shown with a multiplicator of 10.
Is it possible to change this?
Which integration are you using to create your temperature sensors?
They are integrated with Tuya
There are a few similar issues open for power being reported 10x too large. But you should open a new issue here giving as much information as possible including the make and model of your sensors:
