To remove a power controller from a group and restore it to its original factory settings, press and hold the controller’s button for 10 seconds. The controller’s LED will flash red and green twice times during this process; the first flash will happen at 5 seconds. Continue holding the button for another 5 seconds until the LED flashes again.
Your controller will now be restored to its factory settings. You can now add it to a new group and pair it with different switches.
