One of my contact sensors kept showing low signal even though it’s only 10 feet from a range extender. So I removed it from the base station via the app. But now when I try to re-pair it, the app sits at “pull the tab on the back of the sensor” and the contact sensor LED keeps flashing green (3 times). No matter if I press the button, the app won’t recognize it and it won’t pair.
I’ve tried pulling the batteries, factory reset (hold paperclip in pin hole until light turns red), etc. I cannot get it to pair. If I “skip device setup” it shows up as “waiting to connect to a network” in the app while the contact sensor continues the 3 green flash pattern. I’ve also tried rebooting the base station.
How can I fix this to get the contact sensor paired back with the base station or range extender?
