I get a problem that I think is similar/related but with the Wyze Bulb Color. I think it is an IP address issue. I can’t figure it out, but even though my bulbs show a different IP addresses in my router’s app, Whenever I get a power outage, for whatever reason, I only get 3 of 4 bulbs to work thereafter. Then I must “block” all 4 of them in my router’s app, then power cycle the router, then add them back 1 by 1. Then all seems perfect until I lose power again in a few months. Maybe it’s my router (TP Link RE603X Extender). That’s the best way I can explain a possible solution. I do think it is a Wyze product issue. I am not sufficiently knowledgeable about networking to permanently fix the issue or explain it better. I just found a tedious fix and thankfully I don’t get power outages more than a 2-3 times a year. I use a Samsung Android phone to access everything mentioned here.
