You may need to reset an Electric Switch if you are swapping which Genius Hub the Electric Switch is included onto.
To factory reset an Electric Switch:
Remove the white front cover from the Electric Switch using a flat bladed screwdriver. Push the screwdriver into the slot on the underside of the cover and flex the slot out slightly to release the white cover.
If you have successfully factory reset the Electric Switch, then when you remove the power to the Electric Switch and power it back on again, the red light behind the button begin to flash.
The Electric Switch is now in a factory reset to default state, to add it back onto the system again go to the 'Doctor' on the app which is under the 'Main Menu'.
