This is product is discontinued and has been replaced by the ZSE50 Siren & Chime: What does that mean? 

Documentation for the new ZSE50 Siren & Chime can be found here: ZSE50 Knowledge Base

Because the device was discontinued before SmartThings moved from the groovy platform to the lua platform, we will not be creating custom code for the new SmartThings platform for this device. The new architecture is still unstable enough that we need to continue making adjustments for all of our active products continuously, both on the code and documentation side which is draining the resources around platform integration. 

Some basic functionality is maintained for the ZSE19, but since this device is multifunctional and supports Z-Wave command classes that are not included in the SmartThings catalog, much of the functionality is not available on the SmartThings hub any longer.

Let us know if you have any questions! We're always happy to help.
