@Duncan, yes you fixed it!!! The GE45600 Remote works on V2 Hub with Latest Firmware update 0.14.32… I tested it with regular zwave wall switches, plugin modules and dimmer switches…
NO SPECIAL DEVICE HANDLERS NEEDED, ST finds it and works perfect (easy install)!!! Just remember, it can only control other zwave devices… I used the below to configure it:
45600 REMOTE - BASIC SMARTTHINGS SETUP
-Factory Reset/Clear the GE45600 Remote:
-Ensure Remote is not already on a Z-Wave Network (Reset/Clear) and to clear all devices from it (if already installed in ST, then use Removal procedure below, prior to Resetting/Clearing remote):
-Hold Setup till Red/Green flash twice.
-Type 969, complete when green flashes twice.
-Note that none of the remote on/off buttons flash now (all devices cleared, remote is blank)
-Install (Add) GE 45600 Remote to ST:
-In ST App, select “Market Place”, select “+ Connect New Device”, Searching…
-Hold Setup (on GE45600) till Red/Green flash twice.
-Type 967, flashes green rapidly till connected to App/Hub.
-When App says 1 connected, Select Found Item at the Bottom (Z-Wave Remote)
-Name Device “GE45600 Remote-1”, Next, Done.
-Note - the All On/Off feature will work for all Z-Wave devices currently assigned to the ST Hub, see All On/Off Feature below.
-Remove (Delete) GE 45600 from ST:
-In ST App, Things, Select Remote Setup Icon, Preferences, Remove, Uninstall
-Hold Setup till Red/Green flash twice.
-Type 967, flashes green rapidly till removed from App/Hub.
-When App says Success, Press OK and item is removed from Things page.
-Always good to perform a Remote Reset/Clear (above).
GE 45600 REMOTE - PROGRAM/ASSIGN DEVICES TO BUTTONS
-Remote must already be setup/assigned to the ST Hub per the above procedures.
-You can program up to 18 buttons, use the Setup/Shift button to access buttons 11-18.
-Add a Z-Wave Device (Light/Switch) to a Remote button:
-Hold Setup till Red/Green flash twice.
-Press Add (Red Blink), Press Light (Red Blink), Press desired Number (flashes green rapidly)
-Press button on actual device, complete when green flashes twice.
-Remove a Z-Wave Device (Light/Switch) from a Remote button:
-If you press the Delete button vs the Remove button below, you may Delete (Reset the Device to Factory Settings) the device from your ST Hub; to recover the device you may need to force remove it from the App, then Reinstall it again.
-Hold Setup till Red/Green flash twice.
-Press Remove (Red Blink), Press Light (Red Blink).
-Press desired Numbered button on the remote to erase the device from (flashes green twice).
-Note that when an unprogramed number button is selected, it will not flash at all.
-Note that you may add multiple devices to a Group or Scene button, adding multiple to a Light button will only remember the last.
