I have two Z-Wave Plus GE In-Wall Smart Dimmers (SKU 14294) in my house. One dimmer works correctly, but the second one was recently purchased and I am having problems controlling it fro my SmartThings Hub. When I turn off or on the light connected to the dimmer from the SmartThings App the light turns off or on successfully, but the app gets stuck at TURNINGOFF or TURNINGON and eventually shows a status of ON, even when the light is off.
The dimmer that is having a problem has a later version of firmware, “ver:5.26 zwv:4.34” than the dimmer that is working. The firmware of the dimmer that is working is “ver:5.08 zwv:4.05.”
If I reboot the SmartThings hub the new dimmer switch that does not work correctly works and then stops working after a short period of time.
I opened a ticket with SmartThings Support, but they stated they are unable to help me because the Z-Wave Plus GE dimmers are not currently supported. Has anyone else experienced this issue and any suggestions for fixing the issue other than trying to find switches with the older firmware?
