After reading several posts and watching videos, I still can’t figure out how my home is wired and how to get this 3 way switch to work. I’m strongly hoping that I do not need to open up the recessed lights. If anyone with a better understanding could help, I’d greatly appreciate it. Here is the situation:
Overall: One Master, One Add On, Two Lights
- 2 White Wire Bundle, not used in the dumb master installation. Identified as Neutral.
- 1 Red Wire, used in the dumb master installation. In testing, when the Black Line wire was connected to the Red wire, a current was sent to the Red wire on the Add On switch. Identified as Traveler.
- 3 Black Wires, all used in the dumb master installation. 2 were attached to screw A and 1 to screw B. Of the two attached to screw A, one is hot (Identified as Line). The other, I’m assuming is the load as it does not seem to pass any current to the Add On switch (Assuming Load). In testing, when the Line was connected to the remaining black wire (screw B) it sends a current to the black wire on the Add On switch (Assuming second Traveler?).
Add On Wires:
- 1 White Wire, used in the dumb add-on installation. Assuming this Neutral but unsure. In testing, when the Line on the master was connected to the neutral at the master, it still did not pass any current to this white wire.
- 1 Red Wire, used in the dumb add-on installation. Identified as Traveler.
- 1 Black Wire, used in the dumb add-on installation. Second Traveler?
When connecting the smart master and add-on, I can get the switches to communicate with each other but cannot get the lights to turn on/off. I’ve had the same result when using the mystery black wire (that I’m assuming to be the traveler) and when capping it off and omitting it from the install. I imagine the problem is one of three things:
- Something to do with the White wire on the Add-On.
- Something to do with the mystery Black wire on either side
- I’ve fried a switch through some improper setup. Since the blue LED and communication between the two switches works, I can’t tell and I’m unsure of how to test to see if the switch is dead (short of installing it somewhere else).
