Is it possible to power this with a Red On/Off Switch?
I’m thinking it’s not possible since the only place the on/off could go is in Box 2 since it’s the only box w/ constant hot/neutral, but the 4-way has to go there.
Yes, if you use aux switches you should be able to put the Red in either box 2 or 3.
To clarify, I’d prefer not to buy something new. I have dumb 3-way and 4-way switches available.
I understood that. The answer I gave was the only ways it can be done unless you put dimmers in all 3 locations and associate them.
