CPU Speed a little loads the CPU and raises temperature of the CPU

[Enzokot]

The problem

The integration CPU Speed a little loads the CPU and raises temperature of the CPU

I restarted the instance 2 times and delete the integration, after that the temperature of the CPU normalized.
I added the debug log for the integration, but nothing logged.

What version of Home Assistant Core has the issue?

core-2022.4.7

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

Home Assistant Supervised

Integration causing the issue

CPU Speed

Example YAML snippet

logger:
  default: error

Anything in the logs that might be useful for us?

The debug log is empty

Hey there @fabaff, @frenck, mind taking a look at this issue as it has been labeled with an integration (cpuspeed) you are listed as a code owner for? Thanks!

More load usually means higher temperatures. There are temperature peaks (approx. 63 °C) at 03.00 every day according the provided graphs. Your measures show also that the monitored CPU run between 43 °C and and 52 °C.

I highly doubt that the cpuspeed integration is the cause of the increased temperature as this integration runs with Home Assistant's default interval and this would produce higher temperatures over the whole day.

[Enzokot]

Why then i don't see this behavior once cpuspeed integration disabled? Same configs, same hardware. Only one difference - cpuspeed removed.

[frenck]

The CPU Speed integration reads a single, local, file descriptor every 30 seconds. It is hard to accept such an action can cause any of the reported issues in this issue.

Have you tried keeping the integration active, but disabling the updates? (for the sake of science).

[Enzokot]

Can't reproduce the problem. I suggest waiting 1-2 days.
Sorry, but I really want to hear the opinion of the developers: what is better for HomeAssistant performance (in terms HomeAssistant restart or ESPHome compilation) - add more cores or CPU with higher frequency

[Enzokot]

Only disable the integration, nothing else. Will try to check the temperature with host command.

[Enzokot]

Only disable the sensor, nothing else

[Enzokot]

Same with host

[fabaff]

I guess the root cause here is that cpuspeed only works properly with Home Assistant Core (which is mentioned in the documentation). Actually, I'm a bit surprised that the sensor is able to work in a container .

Thanks
