2 days of trying and I am officially requesting support. I have solved or figured out everything else but adding the Z-wave controller to the Samsung Smartthings. as a secondary controller is just not working.
I have enabled the Add/Remove Controller button in the Z-wave settings menu by enabling Advanced Z-Wave Settings.
The IQ Panel will only provide the DSK Pin when I activate the Add/Remove Controller pairing but never shows up as as device while I am scanning with Smartthings. the PIN would facilitate the secure connection once smartthings has started the pairing process.
There are only 2 methods to connect to the smartthings hub , a QR code or by “Scan nearby” . There is no option to begin the process by using the DSK pin.
When I have added the 2Gig panels to smartthings as a secondary controller I would initiate a scan on smart things then activate the controller pairing on the 2Gig and the 2Gig would show up as a device.
I did have issues with the IQ Panel 4 not adopting z-wave devices as a test. It would not recognize any devices until I rebooted the panel. I was then able to add and delete z-wave devices normally. There are no devices connected to the IQ Panel 4 when I try to add it to the smartthings as a secondary controller.
