Looking at the details of this device in the Z-Wave Alliance it seems to be a rebranded "Leak Gopher Z-Wave Valve Controller" from Leak Gopher / Leak Intelligence, they even run the same firmware version, mine is actually on 2.9 which is the same version HomeSeer is using (as per their forums).
Ah, good deal! I was wondering who really made it - I knew HomeSeer didn't.
I only use it in emergencies, so the dashboard not updating/refreshing automatically is just a minor annoyance. Maybe that will be fixed at some point in the future.
I paired it tonight. It originally showed up as "device", which doesn't have any commands. I switched it to Generic ZWave Valve, and it works. I cycled it open and close a few times.
Since it is Zwave Plus, though, I wonder if there should be a "smart" generic zwave plus valve type to support the 'plus' features...
