Reset Intermatic CA600 Dimmer

I am removing all of my devices from a Vera controller and I have a few stubborn ones. I have many Intermatic CA300/600’s that I have successfully paired with SmartThing controller but a few that I cannot get into pairing mode (LED blinks). How are these reset where the LED blinks? Any help would greatly be appreciated :slight_smile:

try pressing the on and off button at the same time for about 10 seconds.
