I am attempting to install either an Insteon ToggleLinc Switch (#2466SW) or a Insteon Micro On/Off (2443-222) to control two ceiling fans with lights. The builder/previous owner created a multi-way circuit with 6 wall switches to control the fans. Both fans are controlled at the same time by the switches. I hired an electrician and he was not able to figure out how to get one of the Insteon devices wired in to replace one of the wall switches.
From what I have read using the ToggleLinc switch in a multi-way circuit requires that all of the existing switches be replaced with Insteon ToggleLinc switches. Can anyone verify that?
If that’s correct, is it possible to replace one of the 6 switches with the Insteon Micro On/Off switch?
Attached are 3 photos of the wiring to the existing switch that I want to replace. If I can use the Micro On/Off switch, does it matter which of the six switches I attach it to? A friend told me that it might make a difference I were to connecting to the first or last switch in the circuit.
Thanks in advance. switch1
