I'm running Octoprint on the Libre Computer "Le Potato" with Ubuntu 22.04 LTS. Currently in Dashboard the CPU temp is 0. When I run the sensors command I get:

scpi_sensors-isa-0000
Adapter: ISA adapter
aml_thermal:  +45.0°C

psutil gives a similar result.

>>> import psutil
>>> print(psutil.sensors_temperatures(fahrenheit=False))
{'scpi_sensors': [shwtemp(label='aml_thermal', current=45.0, high=None, critical=None)]}

I have released a new version with a fix.
