It might be a little bit late but what I understand is Jeremian have a single Lutron green cable (2 pair, one unsheilded 18awg and one sheilded 22awg). If I'm right it's a daisy chain running from control room trough every electrical box (start---box 1---box n---end).
It make me think about RS485 protocol that Industrial automation like Omron uses for remote IO communication. The unsheilded 18awg pair carry 24vdc to supply remote and the 22awg pair carry data via +- channel.
What Jeremian would need to make it's light work the way it was wired is:
- Addressable switch that can be linked in daisy chain and use rs485 protocol
- 15 amp AC outputs
- Programmable Logic Controller to talk with device and trigger the outputs
That said, the only thing I can figure is industrial stuff or HVAC stuff like Strato automation using BACnet. All those solution are not cost efficient..... The main problem with that kind of wiring is that you need a split system; low voltage control on one side and power management on the other side with a controller in between.
That said, maybe there is an other way to solve the problem. If you hack X-10 or UPB switch and use HAI or ELK as controller you could get a long way. Because most of RS485 cable are rated for 300V (
make sure your cable can handle it), you can connect 120v and neutral to all switches
without connecting load. Then, when you activate or desactivate a switch, it would create an event in the controller. The created event could activate a local output...OR, with extra money, it would even be possible to duplicate the non load network in the controller room with the load connected to those switch and use your controller as a ''repeater''. When you toggle the bathroom 1 switch, it tell the controller to toggle the bathroom 1-1 switch.
With the duplicated network, it would be possible to use all function of the chosen network (i.e. multiple scene selection).
It's an untested raw idea so I would be happy if other members could look into it if it's doable.
