how does it work with vera edge? is the siren function supported?
No experience with it. Looking at that device, it is a European product which uses a different frequency then Zwave devices in the USA.
So you would need to be outside the USA and use a VeraEdge-EU for it to even have a chance to talk to it.
In the USA I just use the First Alert Zsmoke or Zcombo.
I can only guess email Vera Support.
