My door sensor refuses to stay connected. I’ve tried it multiple times and it’s the same result each time.
I have the sensor connected to my back door. The larger part on the door and the smaller part on the frame. I connected it first time and so stuck it to the door. Everything seemed ok. however I few days later I noticed it was showing as unavailable. Since this is stuck a metal frame and door it was quite hard to remove, so I tried a reset. Even though the light was flashing green and red it refused to re-add. I tried this numerous times, removing the battery, holding the reset for ages, but nothing worked.
Today I got a Stanley knife and removed the door piece. I was able to scan the barcode using the new (rather than the classic) app. After a while of waiting for the connecting dialog to go, it can up as connected, So I stuck it back to the door. Within minutes it was showing as unavailable. I deleted it ad tried again. Exactly the same scenario. I’ve tried three times now and each time within minutes it goes to unavailable.
When I re-add it, each time it shows open (because I have it with me in the kitchen), but when I take it back to it’s pair on the door frame it stays showing open.
The door on which it sits is in my laundry. It’s about 5m in a straight line with no walls or obstructions to another Samsung motion sensor, which is directly opposite three GE smart switches which work perfectly (as does the motion sensor) There is also another motion sensor in the kitchen (approx. 3m from the door sensor just inside the wooden kitchen door.
How on earth do I get this working? It can’t be too far from a connection if the two Samsung sensors are repeaters as are the GE Switches. What am I doing wrong?
