Indigo Domotics

Do the RD-RD remotes require a traveler wire? The Lutron wiring diagrams show a connection between the blue screw terminals for 3-way lighting circuits. I don't understand the benefit of the RD-RD controls over the dumb MA-AS controls unless the RD-RDs can send a wireless signal to the other control on the circuit. Is there some other advantage?

Yes, they do require a traveler.

That's too bad. So what is the price premium for?

I don’t think you can use the MA with an RRa2 dimmer at all. So it’s RD-RD or nothing.

The MA-AS has worked for me on at least one circuit. It was sold to me by a lighting consultant who is competent with Lutron, but not familiar with Indigo. I spoke with Lutron tech support who said the RD-RD was necessary for the Lutron Connect feature - but that doesn't make any sense - if I wanted to turn on the lights from Kabul, I could use the main switch (or Indigo). The MA-AS is a lot cheaper than the RD-RD. But the higher price suggests that I'm probably missing something.

I’ve never used that switch, and only have a few of the RDs. I’ll have to look at the specs when I get back home.

I’ll ask the lighting consultant.

Maybe the RD-RD capability advantage is dimming?
