Home assistant is too involved to set up… Proceeds to code a basic display that will need endless support.

Home assistant can run on a pi and is actually decently lightweight. Just because behind the scenes it uses containers doesn’t make it complex and difficult to maintain.

My home assistant hasn’t needed and babysitting and is my least involved support project. Upgrades are stable and one-click and you can use as little or as much of its functionality as you want without the sacrifice for performance.
