Trying to install Aeon Micro Switch(DSC18103-ZWUS) onto existing light switch with 3 wires, black, white and bare copper.
Everything I am finding shows how to install a 3-way with multiple wires. I just want to use this on a light switch that’s in another part of the house that turns on the lights outside. I don’t want to change the light switch since it’s install in a 3-slot gangbox that is black. It doesn’t seem like it should be this hard to wire this switch, but I have no “load” wire and I can’t seem to find a configuration to get it to work. Any help would be appreciated!!
If all you have in your gang box is 1 black, 1 white and 1 copper wire you are missing the very important neutral. This is a requirement for most hard wired switches. I would highly recommend hiring an electrician to pull a neutral run from the breaker box. Ive done this myself as everything in my condo was wired with a neutral but my master closet light.
Have you checked the electrical box under the light for the power? More than likely your power from the breaker is run right to the light, and then just the hot wire is looped down to the switch. So if the power is run to the light box you can install the micro switch there, and will not require additional wiring.

You appear to have a load wire (most likely going out of the top of the box), a Line wire (typically coming from the bottom) and a ground (copper). Peak into the back of the box behind all of the switches. There may be a bundle of white wires that don’t appear to be connected to anything but themselves. That will be the Neutral. You will need to make a pigtail from that bundle to create a Neutral wire. If you don’t have that bundle of white wires, it’s like NMK95 said. Although, IIRC, the micro switch does require a neutral.
