Expose Edge TPU temperature

Describe the request

Would it be possible to expose the temperature of the Edge TPU devices in frigate API? And then expose at as an entity in the Home Assistant integration?

I did not find it in the libedgetpu API, but it is available from sysfs in Millidegree Celsius:

root@hassio:~# docker exec -ti addon_ccab4aaf_frigate sh -c "cat /sys/class/apex/apex_*/temp"
66050
72300

I think the original request is still valid, as the sysfs node is not accessible to hass when it’s running in a separate container/host from frigate (and does not seem very portable in general).

Can you try adding this line in configuration.yaml?

sensor:
  - platform: command_line
    name: Coral PCI Temperature
    command: "cat /sys/class/apex/apex_0/temp"
    unit_of_measurement: "°C"
    value_template: "{{ value | multiply(0.001) | round(1) }}"
