I want to run HA on SSD. So I placed the image on it with RPI imager. All works fine, PI boots from SSD, after a while I can see on the PI terminal that all is okay.
However, when I then try to enter my new account credentials everything stops. The HA URL is no longer giving me access, also not if I enter the fixed IP address. Tried 3 times now reinstalling everything but keep running into the same issue? Anything I can check or do differently?
RPis are extremely picky with power supplies and sometimes that is not even enough.
The power requirements are pretty close to the power input capacity, so you need a stable power supply rated at the correct voltage and amps.
The RPis are also designed so they aren’t able to provide full power to the USB ports, on high means the first troubleshooting steps suggested are often moving USB devices to a powered USB hub.
