A 7th-gen i7-powered tiny/mini/micro is perfect for HA. Plenty of grunt for lots of HA addons and integrations, lots of USB ports for dongles (zigbee, z-wave, etc), often with 2x M.2 slots (usually one B/M key and one A/E key) and SATA interface, very low power draw, and cheap due to businesses offloading them all the time.



I haven’t figured out the whole high availability thing yet; I just move VMs/containers to different nodes if I need to bring a node down, or shift resources around, or whatever.
