Thank you for your reply. My interest in HA is solely to have a tool to use zigbee devices like Ikea Trådferi, Hue etc., but with vendor agnostic, self hosted and independent system. I want to controll lamps etc. from our android devices.
I can’t say whether in the future there is interest to include or do more stuff, but since I am not a home owner there is not too much I could think of.
I don’t want to start with HA to become familar with Linux or servers or whatsoever. I am already playing around with stuff like this for years with NAS, Debian Server, OPNsense etc.
When I thought some time ago about it, I had the idea of using a pi to have this IOT/SmartHome stuff completely independent of my other devices and services and to have fine granular control about the network. If I would go this way I would install HAOS on the Pi, since I wouldn’t run anything else on that. I guess with a sonoff stick and ZHA I would be fine.
As I wrote there are two things that make me considder to set HA up as docker on my debian server. Firstly since the machine is already running I spare the energy the Pi would take. Second I read that it’s not uncommon that the SD card gets wracked. Since I have al my services on my debian machine running via docker that would be my go to option there too. Using HA and ZHA with a Sonoff USB stick.
What stands against it is that it increases complexity and chances for failure on my server which I don’t want.
I like your proposal to start of with the Pi and break things and once having it running considder a switch. Is it easily possible to migrate a config from HAOS to a docker HA? I guess it would require at least some fixing compared to just move the data from the mounted folders for the docker containers.
