Hello,
I use Home Assistant Operating System on Generic x86-64 (DELL 6420).
I connected to HA 4x arduino nano witch simple code: button/switch/ds18b20 etc.
i have problem with freeze random arduino. It works good usually but sometimes i cant toogle light or temp is not read. i see logs but i didn’t see problems.
HA send request to arduino to switch realy on:
2023-04-04 14:21:35.927 DEBUG (MainThread) [mysensors.transport] Sending 0;3;1;1;2;0
and arduino not response… 
after restart all it’s ok for few days.
i connected arduino by USB and use myserial gateway 115200 speed in code:
[core-ssh config]$ ls -l /dev/serial/by-path/
