I know that this is more of a question regarding non-SmartThings devices but I am hoping someone has had a similar problem when swith to the Smart Home Hub. I am switching from the Vera hub to an Aeotec Smart Home hub. I need to unpair all my Zwave devices from the Vera in order to pair them with the new hub. I am finding that the Nortek dimmers don’t seem to behave as per the instructions. When I set the controller up to unpair and press the paddle switch twice, nothing happens. The LED doesn’t blink and the controller just waits for the response from the switch. Anyone have any ideas.? The Nortek dimmer is no longer in production so there is no way to get support from them
You can do the Z-Wave exclusion from SmartThings. It was designed that way because there was always the possibility that the Z-Wave controller for a device could be dead.

If exclusion from the Vera hub isn’t working, then factory reset each dimmer device.
