Is it possible to wire three lights on a three-way switch with one motion sensor? Thanks in advance. |

Absolutely. Just depends on how you want to hook it up. If you wanted to turn the sensor on and off and thus use the switches as an override only, just run the switchleg from the 3-way to the sensor's hot, and then the sensor's leg to the lights as normal. Or, run the hot to the sensor, the sensor's leg to the switch box as a hot, and the switch's leg to the lights and then run as normal. This would give you override only when the sensor tells the lights to go on and the switches would be dead otherwise. If you wanted either and both the switches or the sensor to control the lights at any given time, you'd need to power both the switching circuit and sensor, and tail off the switch leg from the switching circuit and the sensor in parallel. This means that you could turn the lights on or off at any time, but if it's dark and the motion sensor kicks in the lights will go on no matter what the position of the switches. If you tell me what you want it to do, I'll draw you up a quick wiring diagram, scan it, and post it here. But I need to know exactly what you want it to do, first. |
This is how I have my motion lights wired. I have 8 motion pairs surrounding my home. I have them on 4 different zones than can be turned ON individually by zones and remain ON. Then I have a single switch that will turn ON the entire perimeter, all eight lights at one time and will once again remain ON. The only difference is that my lights will remain OFF if the switch is in the off position. |
