There is a Caseta Dimmer that requires a neutral wire and has a round middle button that can be set to a favorite lighting level. The cost is about $109.
There is another Caseta Dimmer that does NOT require a neutral wire, and does NOT have the round middle favorite button. The cost is about $59.
I have neutral wires in my boxes, so is there any advantage besides the favorite button with the more expensive dimmer?
Without the neutral, does that mean a little bit of current is flowing through the bulb even when off? Is this a disadvantage and if so in what way?
