I have a hallway with a 3-way switch at each end of the hallway. I purchased HS210 to replace the conventional 3-way switches.
I plan to replace just one of the 3-way switch with HS210 as I want to use the second HS210 in a different location.
So I watched few youtube videos and read some tutorials and all seems to indicate there is no way to identify the "master" 3-way switch in my hallway.
So is it purely trial and error? What I mean is do I install HS210 at the beginning of hallway and see if it works properly and if not replace the one at the end of the hallway?
It seems to me there must be a better way to identify which existing 3-way switch to replace with HS210?!
Thanks in advance.
