i have a small caseta setup (4 switches, 2 remotes) and am looking to expand it. as of now i don't have it integrated with any other systems (homekit, etc).
I want to replace 3 light switches (for my outdoor lights) with caseta switches and program them that if i toggle any of those switches on or off, the other switches in the group do the same thing.
i know how to program a scene of all 3 to go on or off and control them with 1 remote, but i want to avoid getting a remote and instead sync all 3 to turn on or off in tandem.
is this possible? if so, how?
