3 way light switches without running wires ?

[Stevenfyeager]

A customer wants a third switch for a hall light. Two 3 - way switches exist now. That new third switch would be really hard to get a 12-3 wire to. I haven't used any wireless type switches yet. Can this be done without wires, and what brand of electronic remote switches? How do I do this? Thank you.

Contact Lutron but I think you can use the Pico wireless setup. Not sure what you have to do with existing 3 ways.. you may need to buy 2 new maestro switches and use the wireless

The Pico system is awesome.

They make a strap to mount the remote on to a switch box. Only use one powered unit, and tie the wiring through at the other locations and use wireless units there

Those remotes have a 10-year battery, too.

I think the most common ones include dimming, but I just used one that does not have the dimming function

You don't need a switch box for the remote. The bracket attaches to the wall and the remote attaches to it. Just put on a plate. The screwless plates work the best with the Pico.

Correct. It will surface mount.

I was making reference to the wired 3-way/4-way switch(es) which wouldn't be used because the Pico system uses only 1 wired switch. So he would tie through (delete) a 3-way switch. A wireless would mount on that switch box, and added switches would surface mount

You don't have to delete any of the 3-ways, except the one where the master switch goes.
That's what the blue wire on the master is for. You just have to modify the wiring a bit at the last 3-way. Basically, along with the blue wire, you put a jumper between the common and one of the traveler terminals. I have a diagram but not handy right now. It's also in the instructions sheet that comes with the switch.
I use the RF switch that is just an on/off. It's the same exact switch as the Caseta only cheaper. Plus, it doesn't require a neutral. Works with the PICO.

If you're just wanting to add a switch to an existing SP switch circuit just put the PICO wherever you want it.
If you want to add a switch to an existing 3-way circuit (basically making a 4-way circuit) then just replace one of the 3-ways with the RF switch, put the PICO where you want it and modify the wiring at the other 3-way.
If you don't need the last 3-way and just want a switch at another location then you can just wire the last 3-way through and either blank it off or leave the switch but no connections to it.

I didn't know that. But I guess it can wire like the maestro dimmers.

Thanks for the info

PICO would be your best bet in my opinion. All you need is to get one hard wired control switch and two remotes. You can get back brackets for the remote switches so they will fit into the existing spots where you have switches now. And just cut in an old work for the new wireless switch.

As has been stated in the previous replies, you don't have to cut in a box for the PICO remotes. Just mount the bracket to the wall. Decora plates will fit or you get a Claro screwless plate.

Just in my opinion I think it’s a need or look less likely for it to come off the wall by fastening it to a box as opposed to the sheet rock
