SmartThings Multipurpose Sensor (previous generations)

Note: This article is for previous generations of the SmartThings Multipurpose Sensor. If you have the newest version, you can find steps for your device here. If you're unsure about which version of the SmartThings Multipurpose Sensor you own, click here.

The SmartThings Multipurpose Sensor truly does it all: This small Zigbee device acts as an open/closed, vibration, orientation, and temperature sensor all in one. As the most versatile device in the SmartThings family, the Multipurpose Sensor can send you an immediate alert if a door, window, or drawer opens unexpectedly, notify you if dangerous off-limits areas of your home have been accessed, and offer up-to-the-moment temperature readings.

With its built-in accelerometer, the Multipurpose Sensor can also monitor vibration. You can set it to trigger certain actions as well, like telling the thermostat to adjust when the temperature changes in the room.
