🖥️ FHEM in CHROOT installieren, FHEM auf OpenWRT Gerät wie RPi/PC laufen lassen

[Torxgewinde]

Hallo,
Hier ein Skript um ein Debian Bookworm mit FHEM auf einem OpenWRT oder einem Ubuntu hochzuziehen. Bei einem Raspberry-Pi 3 oder 4 muss man arm64 wählen, auf einem x86 nimmt man amd64 und auf alten RPis "armhf" oder für RPi-1b "armel".
