Our house has four conventional exterior floodlights, one on each corner of the house. The floodlights are controlled by a three-way switch circuit with one switch on the first floor and another switch on the second floor. That way the previous owners could turn the lights on manually if they heard something outside.
Right now there is no motion control to turn the lights on. I’d like to add Z-Wave motion control that turns on all four floodlights if motion is detected by any one of them. Here’s the approach I’m considering. Does this make sense?
Retrofit the new HomeSeer HS-FLS100+ Z-Wave Plus Floodlight Sensor to each floodlight fixture.
Modify the wiring in the interior three-way circuit single-gang junction boxes so the Z-Wave floodlight sensors are always hot.
3A. Install a Z-Wave on/off switch in each interior junction box and cap the load wire so the switch acts only as a simple scene controller. A single tap on the top of the rocker would activate a scene to turn all four floodlights on; a single tap on the bottom of the rocker would activate a scene to turn all four floodlights off. If any of the four motion detectors triggers, it would activate the “Floodlights On” scene and that scene would time-out after X minutes.
3B. Alternatively, install a Vizia RF + 4-Button Remote Scene Controller in each junction box. The top button would control the floodlight scene (push to turn them all on / push again to turn all off), the second button would control a “Good Night” scene to turn off all the house lights. I’m not sure what I would use buttons #3 and #4 for.
What do you think? Does this make sense? Is it workable? How much programming is required to make this work?
