I recently installed Home Assistant supervised on an Orangepi zero 3 2gb. This is not a guide, but I want to record some of the steps to make Hoem Assistant work.
- This topic is broadly correct: Installing Home Assistant Supervised on Orange Pi 3B - Community Guides - Home Assistant Community
- I installed Armbian ( Orange Pi Zero 3 - Armbian), there is build labled ‘home assistant’ that includes all the required packages preinstalled. It doesn’t include Armbian-Config but that’s optional.
- Changing the Pretty_Name of the OS doesn’t work anymore so set BYPASS_OS_CHECK=true
- Changes in apt mean that installing from the user folder (e.g. /root/) results in permission errors for the _apt user. Placing the download in /tmp/ fixes this, but I don’t know why. Some people report that you also need to chmod 777 the file and chown to _apt, I didn’t and it worked.
- First boot for home assistant takes a long time, approx 10 minutes. After this it is very responsive.
- wifi, bluetooth, USB all work fine, I haven’t tried GPIO.
My setup uses 700mb ram, with ZHA, ESPhome and bluetooth being the main integrations. 2gb seems to be sufficient, but I think the 1gb would be too little. ESP home compiles take 3-5 minutes.
