Hello Matshj,
I think there’s no such thing like stupid questions 
First of all, take a moment to read this forum guide.
https://community.homey.app/t/tip-problems-with-homey/35744
Info we’d like to see along with your question:
- Homey model (there are 3)
- Homey firmware version
- which app did you install
The first thing I notice (“App Unavailable”) is, you either haven’t installed the Aeotec app yet, or it is stopped or crashed.
