I created a quick tutorial on installing Home Assistant on a Rock Pi 4b+ for anyone that is interested.
It uses Ubuntu 18.04 as the OS. Uses the NVMe drive for the root filesystem (/boot is on the eMMC) which should alleviate SD Card failures people are seeing on Raspberry Pi’s.
This is a brand new setup for me so it has not been thoroughly tested other that the few days I’ve had this setup, but so far it is working great. Much faster than my Raspberry Pi 3+.
