Hi, can I install home assistant as a program in my rp4, with dietpi as my current os?
Or do I need a separate pie with only home assistant installed?
I’m going only going to use 2 automation commands to integrate harmony remote with philips hue lights.
go to dietpi-software and install HA.
thanks found it, looks like I don’t need my pie in close proximity to my harmony hub and philips hue.
So I guess I will sell the other pie I got for this goal, lol
keep it, you never know if not needed later on for other projects
usually a new install/ reinstall of HA should bring you to Python 3.10
ok, what happens to my automations if I reinstall, are they still there?
yes, usually they should persist. Do a backup beforehand to be on save side.
