HomeAssistant on raspberry pie 4 goes to sleep

Hardware

Hi all,

I noticed that every day I have to restart my raspberry pie 4 to make HomeAssistant work again. Looks like it goes into sleep mode or something.
Is there something within HomeAssistant what I can check to prevent this from happening?

How is home assistant installed ?

Via bootable image on a SD card

That is Home Assistant OS. This should not go to sleep.

Should not, but still it does. Maybe not the OS, but is it the Raspberry Pie 4?
How can I check that? Do you know that @francisp
