I would think this is a DTS issue, since the pine64 / pine64 LTS and sopine, which are all A64 based also, correctly report their temperature there - e.g. https://github.com/pfeerick/pine64-scrip...temp.py#L4

I had a quick investigation at this and at least upstream the thermal zones for A64 are defined in https://github.com/torvalds/linux/blob/m...#L170-L216 . This definition is then included in the PinePhone DTS tree here https://github.com/torvalds/linux/blob/m...ne.dtsi#L6 .

However, the PinePhone DTS tree didn't exist until the v5.7-rc1 tag (this is what happens when you try to browse the file at v5.6 https://github.com/torvalds/linux/blob/v...phone.dtsi ).

My conclusion is that you need to be running at least upstream kernel 5.7-rc1 or a downstream kernel with patched in support in order to get thermal working. I don't have an environment set up to compile working images yet so I can't give you anything ready to test, but I think this should more or less solve itself once kernel 5.7 gets released. Smile

I think I should start making new threads instead of hijacking this one though, sorry @devrtz  Angel
