I have a number of 3-way switches I’m contemplating replacing with LZW31-SNs. From what I gather, the aux switch just puts neutral (or open circuit?) on the traveler wire, and the LZ switch interprets that, but I think I must be oversimplifying… maybe a proper aux switch uses a pulsed signal?
In either case, I’d like to keep the dumb switch in place rather than buying an aux switch, but don’t understand how the LZ switch would interpret the state changes from the dumb switch. I assume the dumb switch does not directly control the load as in a traditional three-way. Ideally I’d like dumb switch state changes to be broadcast to the hub where rules can be evaluated.
You guys are the best. Help this lowly mechanical engineer interpret the electrical magic that is woefully under documented.
