Hi there
I have read the Shelly 2.5 forum and have seen a number of posts on three way switching but none have helped me. My bedroom has three way switching for the main ceiling lights. One single gang switch at the doorway and on each side of the bed there is a two gang switch to control the bedside light and the ceiling lights. One of these is an intermediate switch to make the three way switching. See wiring diagram below.
I have wired in a Shelly 2.5 at each of the bedside lights, each on a single channel, in line with the below diagram. My question is, whether or not it is possible to use the remaining channel on each Shelly 2.5 to control the ceiling lights / three way switching. Any advice would be appreciated.
