I had a door sensor fail the other day in the “closed” position. I figured it was the battery, so I replaced it. The bridge (on a Pan Camera) it was attached to saw it. but it never would show “open” again. I figured the sensor had gone bad, so I ordered a whole new sense kit. When it arrived, I tried attaching one of the new sensors back to the Pan Cam Bridge, but it never would connect. I tried the new bridge in another camera (V2) that I already had (that was easily accessible), and it was hard to get it to update the firmware on the bridge, but it finally did.
When I tried to add a door sensor to the new bridge on the V2, it kept failing. I tried the other door sensor that was in the kit, and it worked. The only problem with it was extremely short distance. It would work within 25 feet. I tried putting in a new battery on that sensor, but that did not help.
I figured I needed another V2 camera anyway so I ordered one. I thought I would try the new bridge and sensors using this new camera (and Wyze 32gb memory card). The new camera came in, and I got the firmware on it updated finally, and attached the bridge to it, and the first sensor would not connect (as before, even with a new battery). The sensor that had connected successfully before connected, but still the distance was very short. The sensor I was replacing would consistently work well at over 50ft with the Pan Camera/bridge. I then tried to order another sensor kit from Wyze, but they are now out of stock. I figure either this bridge, and/or the door sensor(s) are bad. I have done several installs on these, so I am not a rookie. I am beginning to wonder if this new kit I received is defective. I don’t want to deal with a long Tech support runaround, so I will just wait for the new batch to arrive in stock, and buy another round. I have about 4 bad wyze door sensors in a box. Hopefully the next batch will be of better quality. I also notice that sometimes the sensors arrive with batteries that are already about spent (tested with a digital multimeter). Thanks, and good luck to everyone out there, stay safe!
