I’m probably late to the game, but I had this problem and tried everything mentioned in this community forum - everything failed over weeks so I finally looked in support and found that it suggested if I had a ASUS router to disable Airtime Fairness – well, it worked in my case. In the last 36 hours my bulb has sat compliantly off. I feel a bit sheepish that I relied only on the forum and not support docs.
Please don’t hammer me with comments - if this is old news to the community monitoring this. I didn’t see any mention of any solution since the previous posts to this.
