Doesn't work for bulbs. I don't know if it's the app or the bulbs themselves but I don't really care. I kickstarted those Wyze bulbs and now I have 8 bulbs that drop their connection constantly. The app sucks. The bulbs suck. Avoid Wyze. 3/8/22: somehow they continue to make things worse. I finally got one bulb to work regularly. Then they offer me a firmware update which I accepted. It failed, leaving the buib again in an unusable state. F this company.
