The instant I saw that part of the video I was reminded of how I had to hack an MQTT debouncer for my doorbell sensor (which is a repurposed ZigBee door sensor with a magnetic reed switch placed near the coil). Every time the doorbell rang I got 10-20 “sensor open/close” events, which was fun. (Ended up using just one Node-RED trigger node with a suitable interval, since I already had that in the loop)
