I bought a few of the pressure pads used for heated seats in cars and then hooked it up to a zigbee door window sensor. I just soldered the sensor ends to the reed switch. I use them for smart fatigue mats so my work bench powers up when I step on the mat and then 20min of non stepping has it power off the bench. Keeps me from forgetting to turn off my bench PSU and solder iron.
