These little sensors work great with SmartThings with Xiomi/Aqara Device Handler. They have a faster response than my Z-Wave motion sensors and this allows me to set up an automation that turns the light on and off automatically. They're half the price of most Z-Wave sensors, and their small size means they can be placed almost anywhere. So far, battery life appears to be good with the CR2450's lithium coin cells. They also report brightness values, which can also be used for automation procedures.
