I got one of these for Christmas
Its got a red LED, and works as a normal Zwave Siren. I coupled it up with the delay SHM smartapp, and it works sweet!
One thing I really wanted was the ability to run everything “local”, so if the power or internet goes out, the alarm would still work, a lot of the 3rd party device handlers rely on the cloud, but this seems to work as a general Zwave siren, and it REALLY loud, I put it in my loft space. It has a battery backup and USB power plug… just have to hide it away in the loft!
