Zigbee has several different “profiles” and they are not all compatible.
Smartthings uses the Zigbee home automation profile (ZHA 1.2), so devices that use that same profile are the most likely to be able to work with smart things.
The sensor you have uses the zigbee pro profile. Some devices using this profile can be successfully used with SmartThings. Others will pair OK and work for a few hours or a few days, but keep dropping off the network. That’s because they are expecting a response from the zigbee coordinator which is not part of the zigbee home automation profile and so SmartThings doesn’t send it. You will find a lot of discussion of this issue in the forums on various zigbee devices.
In addition, there is a security option in SmartThings which allows you to do what is called “secure pairing”. This can also cause problems keeping some devices connected.
So the short answer is you might be able to get the sensor you have to work, but it’s going to require a custom device handler And you may still run into the drop off problem.
When you’re looking at new devices in the future, if you stay with the ZHA profile everything just works much more easily.
If the sensor you have now has the option to shift to the ZHA profile, then that would be my recommendation as a place to start. some devices can be upgraded in this way and some can’t. You just have to go back to the manufacture site and check.
