I had a simular idea :)

I want to introduce to you: "Domowoi the Hausgeist". The ghost, who doesn't look after your home assistant, but your house.

Domowoi checks every room for Heating or Cooling related issues and easy to invite to your home. just put him onto you dashboard and he automatically flies through your rooms scanning for window/temperature/humidity/occupancy sensors, heaters and other good stuff. He even reminds you to open the window if it is smart to do a german "lüften" and also reminds you to close them again if it should start raining.

Currently he is still a young ghost but he develops fast but always welcomes new teachers or new homes to spook in. He also told me that he would love to meet the mysterious spook and maybe learn from him or the other way around :)

He currently waits here to meet you: https://github.com/strhwste/Domowoi
