I just added 6 Sengled bulbs into my mix and have had weird issues so far. 5 of them are in a single fixture. Oddly, I have 3 in another fixture that I've had since 2021 without the problem, now they are doing it too. The change I made is I put them in a group dimmer in my Hubitat C5. The 5 in the other fixture are in another group dimmer. My problem is with using the actual hardwired light switches. I still use my hardwired switches too. When I turn them on, after a second or two, at least one will turn off. Sometimes, they all turn off and that's when I just want to rip them out. Flipping the switch off and on again won't help, I have to go into the hub and turn them back on. There are turn-off events in the hub and I just have no idea where they are coming from. But these are set up exactly as the bulbs they replaced. If I put other branded bulbs into the group with them, those have no problems. I've tried all I can think of, so I'm about to return all six of these. If they can't handle being switched like an actual light bulb, I don't want them.
Maybe we find Sengled bulbs expect power 100% of the time? If our issues could relate
