This is a conversion of my SmartThings DTH for the Hank One-key Scene Controller. The device almost works perfectly with the integrated "Generic Z-Wave CentralScene Switch", but things like the value for battery falls away. Also, the device has a tendency to send the same command twice sometimes, so I have added a check for duplicate sequence numbers.
Ah, makes sense! I guess battery based central scene devices isn’t that common.
I will convert the four key version of this as well, but as I don’t own the hardware myself it’s hard to test. If I just make the same changes to the code all should be good, though…
