GreenIQ Smart Garden Hub can control garden lighting. To complete the
installation you will need an external relay (available on GreenIQ on-line
store). A relay has two major ratings: coil rating and contact rating. The
GreenIQ Smart Garden Hub supports relay coil ratings of 24VAC and up to
150mA. The relay contact rating should be determined based on your
garden lighting voltage and maximum electrical current.!
