Use Mirror feature to fix a broken wire problem

All,
. I have a 3 conductor AC line that runs from my house to patio. And I have several motion sensor floodlights (think Driveway lights). I have the motion sensor outputs connected together in a “wired-Or” fashion. So if any motion sensor trips, all the lights turn on. ie: if a motion sensor trips, it doesn’t matter which one, all the lights turn on. Works great! See diagram.
. Then the red wire got cut. Instead of digging and burrowing under a cement walkway to replace the conductor with a new wire/conductor, I’d like an easier way. Like maybe use the “Mirror” function.
. So the red wire, on either side of the break, will have 120V or 0V, regardless of which motion sensor tripped.
. The mirror feature ALMOST sounds like a solution. But from my reading, the mirroring is One Way. I need Two Way mirroring. The motion sensors on either side of the break should be able to energize & de-energize the red wire on either side (both sides) of the break.
. I hope I explained that clearly.
. Any ideas? TIA
. Fastb


How is this related to SmartThings? Even the motion sensors seem to be dumb ones.

  • Fair Question. Right now, I don’t have a Smartthings Problem. Instead, I’m looking for a Smarthings Solution to a non-ST problem, ie: a broken wire.
  • I have 15 to 20 smart devices, mostly Smartthings devices. Smart devices have handled things creatively. I’m hopeful there are devices I could use for this broken wire.
  • Thanks in advance!
  • PS: the generic motion sensor “driveway lights” are dumb…

3 smart outdoor motion sensors and smart flood light bulbs would be the simplest solution.

Or 3 smart outdoor motion sensors and smart switches.

Simple routine if any motion sensor detects motion turn on all flood lights and automatically turn off after X minutes.

Another option. A smart relay similar to the following. Caution: most smart relays have 2 switch terminals and will NOT work for this application. The following relay only has a single switch terminal (S1) and should work.

Wire dumb motivation detector as follows. Black to line (L), white to neutral (N) and red to switch (S1). Adjacent flood light can be wired to L1 (load) and N (neutral). Incoming power to L (line) and N (neutral). The relay needs to be in a waterproof plastic electric box. A metal box could block the radio signals.

Use routines to turn on all spot lights when one turns on, and to turn off all lights after X min.
