I picked up a set of these Quirky+GE Tripper window/door sensors. I quickly added one with no issues. I had some difficulty adding the second one. I noticed that the LED wasn't lighting, so I swapped out the battery from the one that was working. This seemed to get the second one working. I then had to find a second battery to get both working at the same time. In this process I mixed up which was which, so I decided to remove both from the Almond+ (batteries may have been out of the sensors). Since doing so I cannot get the sensors to re-add to the Almond+. I have tried the remove feature on the "add a sensor" screen with no luck. As I have over 20 sensors and even more rules setup, I dread using the "remove all sensors" or doing a hard reset. Any suggestions to get these working?
