Random Reboots of HA installed on RaspPi 3 Modell B

Hello everyone,

I have a strange problem with my HA on a RaspPi3 model B. Basically, I have been using this combination for years without any problems, but since our move and the change to a new smart home system, I have the problem that the system restarts sporadically and unexpectedly. After this restart, it works perfectly again, and there are no problems until a restart.

Compared to the old system, I have hardly installed any integrations, HACS and add-ons. The old system was a patchwork quilt. With the new system, I made sure I had a homogeneous system. It mainly runs Homematic, plus Hue, Fritzbox and Netatmo. The number of automations is also significantly lower than before, as many things are already controlled directly by Homematic and the HA server only takes on additional control tasks.

The only add-ons installed are Samba share and Mosquitto Broker.

That’s it, in the old system I had a lot more installed without any problems, I also had AdGuard running… Because HmIP does a lot internally (windows open and such), there is also significantly less automation running here than in the old system (both in terms of complexity and number), so the new one should have significantly less to do than before.

The last few HAOS and HA core updates have pushed the limit of what is possible on a RPi3 down significantly.
There are quite a few threads about it.
