I experienced my 4th HA failure in a few months, but only realized today that it might be hardware related.
We worked on my solar system yesterday and we had to switch off the battery and that affected my 12volt bus supplying my Intel NUC. When we switched the power back on, the HA instance did not restart.
Tried everything I could but the Nuc reported “No Boot device found” even though the complete installation is visible when i connect the hard drive to another Linux machine. This is when I realized the previous 3 times it also happened when I had to switch off the power. I then have to reinstall the Image to get it running again. After installation, I can reboot the HA server as many time as I like and it will continue running as long as the power is available, but if I reboot the device or cycle the power, I can forget about getting HA running again.
I guess I will be going back to a PI4 with an external hard drive, its way cheaper than replacing a NUC at R7k and upwards… I bought this NUC in 2016, lasted 5 years…
Any hardware recommendation except for PI4
EDIT: I dont want to run it on a normal PC as I want to keep HA live from the batteries directly.
