Turn on your lights when you're not home to deter burglars. Switch on the living room ceiling fan so your home will feel fresh when you come back. Turn off the lamp across the room because you're comfortably snuggled on the couch and the cat is sleeping on your lap (hey, we've all been there).
These are just a few ways your everyday life can be simplified with SmartThings and connected devices, like a smart relay for controlling lights and appliances. The Smartenit HA Dual-Relay Controller ZBLC15 (4033A) is a ZigBee-based, multi-port relay that definitely fits the bill. SmartThings does not support independent relay controls with this device, however.
