HomeKit Homekit randomly turning devices on and off?

I have several Wemo and Hue devices hooked up in my home. Two nights ago, one of my Hue bulbs in my Living Room lamp kept turning on randomly. It happened about 8 times that night and is the first time it has ever done that. I ended up turning the lamp itself off and back on and it seemed to stop since it did not happen last night. None of my other Hue bulbs had any issues.

Last night, a fan in my bedroom, hooked up to a Wemo plug, kept randomly turning itself off. This happened about 5 or 6 times throughout the night. None of my other Wemo devices and Switches had any issues.

I don't think anyone hacked my Hue, since I don't even have out of home control turned on, I handle that through Homekit, and it would be a little weird for devices on two different systems (Wemo and Hue) to have been hacked at the same time. The only really common thread would be Homekit. Has anyone seen any weird behavior like this with Homekit?

I had that happen a couple of times and never figured it out. I have wemo smart plugin switches and Lutron Caseta switches along with hue motion sensors. The only thing I thought could be responsible is that while one of these hubs were updating it caused the problem. I have not experienced it again for over a year.

Hue lights turning on and off by themselves usually means the bulb is going bad. I’ve seen one or two over the years; usually bulbs in enclosed fixtures. Take the offending bulb out and toss it in a spare lamp and see if it still goes in and out, help confirm it’s the bulb.
