I have been continuing to poke the engineers about this. They say that power cycling the Wyze Cam SHOULD usually resolve this but for the people here it doesn’t sound like it does. Could you please message me with the MAC address of the Wyze Cams that aren’t showing up consistently, the time that you tried to connect, and your time zone?
Also, the Alexa integration SHOULD work in North America but other locations won’t have the skill available.
