I'm trying to do something that seems very simple to me, but I can't seem to find any products that can do it. I'm trying to add a second (remote) switch to an existing single-pole dimmer switch, effectively creating a standard three-way dimmer switch setup, but with one of the two switches wireless. I have no problem replacing the existing dimmer switch, but I'd really rather not have to run any wires. I could provide a constant hot to the wireless switch, but I'd rather have one that ran on batteries.
The existing setup is a simple single-location, single pole/single throw dimmer switch, which controls the lights in my living room. I would also like to switch the lights on/off from my bedroom doorway, on the other side of the room from the existing switch. Control of the dimming level from the bedroom is not necessary. I would like something that is wireless, and that sticks to the wall and looks like a light switch. All the products I've found seem to be not quite right, or designed for something slightly different.
