@tom_l The repo you linked to is for the Home Assistant documentation, not Home Assistant itself.
@coza73 I would suggest opening an issue in the Home Assistant repo you linked to. Even if you can’t make a PR yourself, somebody else can, especially when you’re already providing a fix!
For the record, this bug seems to also affect the CPU temperature sensor on a Raspberry Pi 3. That same sensor works fine on a Raspberry Pi 3 B+. In the Glances web UI, the sensors are shown differently: bcm2835_thermal 1 for the RPi 3 and cpu-thermal 1 for the RPi 3 B+.
