Greetings all I have a typical 'dead end 3-way' switch at the end of a hall in a existing modern house with limited access no attic etc(call this box B)
The customer would like to add a light directly above this switch box, but since its a dead end 3 way, we'll be running a cable to tie into the main switchbox (call it box A).
I have 2 design rules for permanently installed, hard wired electrical devices:
1) They shall not rely on a battery for primary operation.
2)They shall not have any reliance on WIFI or 'wireless' anything for primary operation.
I seem to recall a dimmer or a switch that could use a single wire to communicate, freeing up the white wire in the 14/3 to be used as a neutral.
I am a only finding current products (looked at Lutron) that use either batteries or wireless which like I said I'd like to avoid.
Thanks in advance
