Ok so got a major power cut in the building, power away for +90 mins  
Many devices came back with red exclamation mark (!), saying driver unavailable, which is a known issue. Using the web interface was just showing the same as in the app, and when looking at installed apps…apps missing.

I reinstalled the missing apps, and yes, all connected again, except 1…aqara plug, saying missing App Host…

EDIT: OK so the final device works now, just needed some time (to find the bridge I guess 🙂 )
