but it's combined with another issue. Yesterday this particular bulb worked just fine. This morning Alexa told me it was offline. I used the Kasa app and it worked fine except that it said local wife only. Then that note disappeared but Alexa still couldn't control it though it could rediscover it when I asked it to do so. So then I had Alexa "forget" it and I went into the Kasa app and disconnected it too. But then I had trouble getting it reconnected. And for some reason it would only blink twice instead of three times. It did finally connect when I held my phone right next to the bulb. Finally I had Alexa rediscover it, which it did and Low and Behold! Alexa can now control it again. sigh. but I still love my smart system. I see that other people with other brand devices have the same problems. Guess it's just part of the wi-fi world.
