Am I missing something ? (wyze bulb)

Yup. It works fine. Two door sensors turning lights on when open and off when closed for a length of time.

Now the only issue with Wyze products is the motion sensor does not have enough range to be connected with camera bridge when placed in another part of the house. The door sensors and motion sensors have to be in close proximity to camera bridge to work. So having one camera bridge will not work to cover the whole house unless you have a studio. They should provide the bridge free of charge with each camera.
