HA restarts every 7 or 8 hours

Installation Home Assistant OS
1

After the latest core update i have HA restart every 7 or 8 hours. I tried to remove some apps but that doenst change anything.
Its bit unclear if the API causes the restart or a app.

I think it is always unclear of you home assistant has restarted on it’s own and why it did that.
There is no uptime sensor as far as I know, or some sensor that reports when the last manual or automatic system reboot was, or when there was a manual or automatic restart.

I think it would be nice if there were some sensor for that, and better error reporting in the logs to find out why, and what’s going on in the system sometimes.

Start by disabling this app (add-on). What hardware are you running on? How much RAM?

There is. Uptime - Home Assistant

Same issue Here every 7 a 8 hours after latetst update It’s begon

Running any HACS/Custom Integration? Many times they need updating after Core updates, so you can try with all of them disabled and slowly reintroduce one by one to see if any of them is the culprit.

You can also check each repo for each Custom Integration if others are reporting the same.

I have the same Issue

Nodered had two updates on my system, and it indicated that it was not healthy and was going to restart. After installing the updates in Nodered, I haven’t had any problems since.
