What is needed to program the light? Can i program direct from phone to unit or do i need the gateway to do any wireless programming?
Question by: Donald Schultz on Feb 7, 2019, 3:27 PM
Thanks for contacting BRS!
The gateway is necessary to connect to the light allowing for control for the Orphek Atlantik, and one gateway can control up to 200 lights. Have a great day!
