One of my lights (an A19 white and color bulb) keeps turning back on when I turn it off with the Hue app. This just started happening, about 9 months after working fine. It is paired in a room with another light (just white) which behaves normally. Both lights were on a routine; I’ve tried removing the routine, but this one color light still goes back on one second after I turn it off. The only way to turn it off is with the old electrical switch. All other lights in my house behave normally. There is a long discussion of this problem on reddit, but none of the solutions suggested work for me. Could the bulb itself be defective? Any suggestions?
