Review: Works with 12v low voltage lighting - I purchased this in hopes of controlling different areas of low-voltage lighting independently in my backyard. Most transformers are single channel and the multis are crazy expensive. I previously had a smart plug in the transformer to link it with my other lighting. Wifi signal out to the transformer was always a challenge. This unit has no problem staying connected and reacts instantly to Smartlife triggers. The wire ports are a little small but handle 12awg wiring.
Review: Works really good!! - Using it for Halloween props, skeletons that you get that have the momentary display push button, actually cut off the momentary button and wired the 2 wires to the N/O contacts on this device. So i can program all the eyes/lights to go on and off with the rest of the Halloween lights/props on a time cycle.
