Even pi3/4 is not a fast piece of hw, but I see CPU spike from 0.6 to 4+ for hours daily. It seems like some sort of daily cleanup kill the pi.
When CPU usage is low < 1.0, HA is responsive
I don’t have issues with Pi 3, so I have some question to double-check the issue:
- Are you running the HA RPi image?
- What Add-Ons are you running?
- What is the class or speed rating of your SD-card?
- latest HassOS 4.12
- add-on: File editor, InfluxDB, Mosquitto broker, Portainer, Terminal & SSH, flicd
- using a samsung evo select 64 GB (a class 10, U3 (??))
Now, thinking for a bit, maybe influxDB? I am going to stop it and see if the problem goes away.
My test instance of HA runs on a Pi1, and even there I cannot say HA become unresponsive.
I have flic buttons as trigger w/ flicd add-on. The setup automation that use flic button as trigger to turn on/off hue’s light
When CPU > 1.0, button trigger takes 10+ sec to take effect.
If you are running HA Core on your Raspberry Pi, I used to have performance issues with this (sometimes hanging completely) until I set up a ZRAM swap file (following these instructions).
I had also previously switched the database to MariaDB, which made a slight difference, but I was still having issues. Since setting up the ZRAM swap file I’ve gone months without issues.
I will give it a try. Thanks
If running HA OS this should work:
