To go to Cameo Lighting on a 3-way switch, which dimmers can I use? I see the Cameo Express are cheaper. Can those be used in a 3-way location or should we just go with CLW-DIMEX-P and use the slave dimmers?

You will need the remote Switch/dimmer at each 3/way location. They don't work with normal 3/way switches.

Re-reading my question now, I see it's confusing.

I understand that the switches NOT AT THE LOAD need a slave. My question is can I use the cheaper CAMEO EXPRESS switches (CLW-DIMEX-E) in a 3-way location as the main dimmer? I don't see a slave for the Express Dimmers, which is the reason I am asking.

I see that the regular Cameo has a slave.

Yes you can combine both "E" and "P" series switches. The problem with that is if you look closely at the specs the LED's are different colours (E = Green, P = White). To keep the flow I would install all "P's" unless the customer requests otherwise.

Going in a home that's being put on the market in just a couple locations so it can be touted as having automated lighting. Already a crestron system in place, just no lighting.

I usually spec a CLW-DIM-EX at every location and dont use slaves. You just cap off the load wire on the dimmer at the remote location. This way you dont need to figure out where the load is connected and whether you have a 3 ,4, 5 way when u spec a job. Just count the amount of dimmers / switches in the house and replace with all DIM-EX.

So you can state for a fact this will work? Using all Express Dimmers? Much easier to just order it that way. Cost isn't much more than the slave.

I'm no electrician. How does this work without a traveler?

You treat it as a single pull dimmer, just provide power to the dimmer in the other location and then marry them together in programming.

Stupid me. I knew that. Sometimes I get ahead of my brain and forget what I already know. Done that several times with Lutron. Thanks for the reminder.
