Hi, I'm looking for some kind of controller with a remote so that I can control the halogens with built-in motion sensors in front of the house. I would like me to be able to switch the lights on and off and also switch them to auto mode so that they detect movement when someone approaches. It would also be nice if it was possible to dim the lights, but not necessarily. What kind of remote control would you recommend? The controller would be outside, but under the roof, so it would be good if it could withstand moisture. The halogens are 230V.
