I am using HA since September last year. Installed on Raspberry Pi 4 with 64gb SD card. Followed the regular installation instructions.
It is working quite okay, but since a couple of weeks now the system crashes each week in the night from Sunday to Monday around 01:15 - 01:30.
The Rpi does not have an IP-address any more, I cannot reach HA any more, the only thing that works is to power down the Rpi and restart the Rpi and HA.
I can see in the history of some entities this happens around the above mentioned time and the values in the history remain the same (CPU% of RPI, temperatures living room etc.) until the restart.
Is there any HA task scheduled once a week on Sunday-Monday night that can cause these issues? or how can I recover this information, since after a restart the HA logs are cleared and restarted as well.
Thanks in advance for some feedback,
