Can't install core; ERROR: Could not find a version that satisfies the requirement homeassistant==2023.3.5

:laughing: Then you will likely have a lot of fun trying out ESPHome! This will be fun for you! :wink:

Don’t get overwhelmed!

And for your Somfy, I would take a close look to this project:

ESPHome is perfectly integrated via an official Add-on (to run the ESPHome software) and a nice integration into HA (the ESPHome integration, so the Add-on can talk with HA and vice versa). You will find a lot of information on the ESPHome page, but in short, don’t bother with writing “complicated” Arduino code, you can just do it easy in ESPHome.

That’s what I was meaning in my post above. If not covered by HA with its over 1000 integrations, there is mostly a custom component available, like the one above.

And as you can see, it has a lot of advantages, to not run these things on a Pi, for most cases an ESP device has a much smaller foot print. Lower energy consumption, smaller size, easier placement and so on.

My advice still stands :wink: , install HA-OS on that Pi and take your first swim in the big home automation pool. You might get addicted, if os, see you soon in this very forum! :rofl: :rofl:
