I have migrated my setup to an RPi 5 with an NVMe. I did not perform anything specific for that setup. I just used the “move data files” to use the SSD rather than the SD card. I think there is still an action to do to have a better performance, but I presume it is not the issue here.
I already had 2 or 3 times that the system hangs (some automations still work, data is not collected, UI doesn’t respond). The only way I got the system to work again is to cold boot it. I therefore believe there is some low level issue.
That led me to think about the RPi firmware. Is this something I should take care of, or is the OS dealing with that?
I still need to try to run the command in RPi4 EEPROM version information in HA - #19 by eikowagenknecht.
