The problem is the GE brand lights. This is a well-known problem, nothing to do with smart things. In fact it’s the reason why this brand is not on the official “works with smart things” list. From time to time, they can just forget what network they’re on. It’s extremely annoying, and there is no fix.
Most people now buy the $15 Hue white bulbs instead if you need A19s, and the Osrams if you need floods, although those are more expensive.
