Love this review! Just wanted to mention that the companies installation video says that if you install it to “parallel connection switch” … which is the light fixture that the group of lights wire from, you can use one to control a group of lights. I’m just not sure how you figure out which light has the wiring for all of the lights.
You’re right! It is a switch, not a relay. I mainly just compare it to a switch because it’s so similar, and this is my first time dealing with a smart relay
