Thanks for bringing this to our attention. There could be an issue with the controller’s Zigbee service. Take a close look at the Zigbee LED light when you put the controller in inclusion mode and make sure it blinks, listening for joining nodes.
We’ve opened a ticket for you to provide some info about your controller. Check your email.
Had a similar issue after the original batteries died in my two devices after only 6 months. One restarted immediately once the new battery was in. The other had to be reset - process I used: with the battery out of the sensor, push down and hold the reset button then reinsert the battery. That did the trick for me. I was then able to do the inclusion process.
