I haven’t used a rpi3 in a wile for Hass.io. I wanted to get a tester up and running.
I previously just flashed a SD with the latest Hass.io image and plugged in ETH, SD card and power on the rpi3 and it booted. And bingo 10+ mins later I could log on.
Now all I get is a screen with:
Net: No ethetnet found.
starting USB...
USB0: scanning bus 0 for devices... 3 USB Device(s) found
Hit an key to stop aoutboot: 0
HassOS>
A eth cable is plugged in and works fine with a raspbian OS SD cards.
" Currently only a manual configuration using NetworkManager connection files is supported. Without a configuration file, the device will use DHCP by default. "
I had no issues. If you are reusing an as card did you use SD Formatter as recommended by Raspberry Pi? Some people here have had issues without doing that.
