Some months back we purchased Amazon echo and then progressed into buying a Insteon home kit. We loved controlling outlets but as time went on really wanted to automate all of the house, as best as we could. Over the last six weeks I've purchased 18-switches (dimmer and on/off). I'm comfortable swapping out light switches but when I saw they needed three wires (including the neutral) I started calling electricians. Now I'm looking at a pretty hefty bill along with having many walls in my home opened or damaged so (as my wife says) "I can have my toys".
Recently I met with someone who shared with me that the Lutron RA2 does not require three wires. Is that true?
Also, what additional will I need? A bridge?
Sorry, very new to all of this. While I have been reading up I just don't want to make another mistake again.
Thanks in advance.
