I read other users complaining that the default driver didn't work (@steve.maddigan):
What happens is that after the factory reset and the pairing, the first couple of rings were intercepted, then it stopped catching other ring events. I tried removing and inserting the battery from the sensor, but it still didn't work. If I factory reset and pair it again, it does the same thing, it works at the beginning, then it stops working.
What I noticed is that when it stops working these State Variables are shown under the device page. When it works they are not present. Also, I didn't understand what the "Configure" button does there.
Hope it helps Mike.
