Axxess Contact Sensor (Will a Control4 Sensor work with SmartThings?)

The SmartThings hub supports zigbee HA. Zigbee HA is a subset of Zigbee Pro so it may or may not work. If you are looking for hidden door sensors that are known to work the aeotec hidden door sensors work well with SmartThings. The newer gen 5 I think still requires a custom devicetype.
