Every now and then I find my processor is running hot for no reason. There's not much running on it. It's a RPi5 with fan and HA with influxdb and grafana so i can plot it.
It suddenly ramps to 100% fan and 70C core temperature. The processor usage went from 0.5% to 25%. Logging into the HAOS and using top I can't see any processes jumping out as the reason.
I'm helping my son with his new home and HA and he subscribed to HA Cloud so this is all rather frustrating.
Any tips for how I can find what sub process us causing the problem
