For this guide to work Vera needs to be near the GE 45600/45601 remote.
On Vera :
Go to the Dashboard > Devices > Add device > Click "Add" next to "Advanced Z-wave devices" > "Add one" under "For battery operated handheld remotes".
On the remote:
Press and hold SETUP until "LGHT SETUP" > Scroll right to TRANSFER (should be 5 presses) > OK > Scroll to RECEIVE (2 presses) > OK.
Vera will add the remote, and you will be able to create scenes and assign them to a button using a trigger, and you can read more about it here . To transfer the scenes to your remote, put the remote in transfer mode and Vera in include mode and wait until it finishes.
Note: If Vera won't see the remote choose to remove it first and then try to re-add it.
