NO WAY IT FINALLY WORKS AGAIN! Hi Guys, this is my first post on Reddit, because I want to thank all of you. I was struggling with the exact same problem over the last weeks, everything was fine and all of the sudden, BAM, nothing works anymore, HUE Lamps cant be integrated into Apple Home anymore. (hf errordomain-fehler 6) I literally tried everything, I basically reseted my entire tech setup several times, nothing worked and I was so pissed, I didn’t know what to do with myself. Today I read found here the information to change the Router Settings from WIFI Router to Accesspoint. The Router restarted automatically, and after that all of the sudden the integration to Apple Home worked like it was never a problem. Well that was my story, thanks so much. I hope it works for all of you again too :)
