I’m new to Home Assistant and Raspberry Pi and could use some help.
When I reboot Home Assistant OS on my Raspberry Pi 5, the fan in the official case starts spinning faster, gets louder, and the system never reboots. I have to force it off.
You mean when you reboot the system? When I do a restart with a Pi5, I have no problems. When I do a reboot of the system, it hangs as you described. Although I can’t read whatever language is in your snapshot, the red button you show in your snapshot is the same as my ‘reboot system’ button.
Since I don’t need to do a full reboot often, I just ignored the issue and power cycle it after a few minutes of waiting. I guess it isn’t just my setup…
I have a powered USB hub attached to my pi5 running HAOS. If I want to restart the host system I have to power cycle it because the powered hub appears to be back-powering the pi making it not restart.
Just a side note: File corruption problems could occur if power cycling before the system is completely shutdown (through a proper system shutdown).
I would expect a reboot not to hang unless there is a problem. Check ALL the logs to see if there is any information. See #5 here: How to Troubleshoot Raspberry Pi Crashing.
Although I have an external USB powered SSD that HA runs on, it is not externally powered so that isn’t what is occurring with me (at least). I have nothing else (aside from the cooling fan) that is connected to it. Interestingly my LAN LED light doesn’t flicker when running either (whereas my other Pi5’s do). But I can’t imagine that has anything to do with HAOS…regardless I thought I would mention it to cover everything hardware wise.
I don’t think that type of power to the pi has anything to do with (un)proper reboot. MCU should restart when keeping it fully powered.
Connect LCD monitor to Pi’s hdmi output and observe if there’s anything usable saying there why it hangs. But it’s definitely software problem, if you ask me.
