I noticed a few days ago that one of my hue bulbs wasn’t working. Today, I went looking for it in my devices, but it seems to have disappeared. It is however still listed within the built-in Hue integration app and I can control it within the Hue iPhone app.
I can also still see it under some other apps like the Group app:
I really doubt that I would have deleted it, so I’m not sure how it went away…. Since I’m not sure exactly when it disappeared and made some time consuming changes on this hub, I can unfortunately not restore an earlier database.
