Now that I got my Home Assistant Thread Border Router working with a Aqara P2 Matter over Thread contact sensor it was time to stress test not only the sensor but also the pieces that make the solution work.
Contact Sensor -> Border Router Dongle -> Home Assistant Border Router -> Ethernet -> Hubitat Matter -> Rule Machine.
So last night I put the sensor on the Wife's keyboard tray and when she opens and closes the tray a Dome Siren's "Chime" goes off like my garage except using a different tone. I didn't tell her about it.
Well this morning I was laughing as she was working on her computer I heard the chime go off like 6 times and she didn't coordinate the chime to the keyboard tray. 
She came over to my office and said why is the chime going off. I had to admit that she was my test subject. I have since moved the sensor to a door to continue the testing but this was so funny.
