I had an X10 installation with 3 different light circuits (exterior floodlights) controlled by 3 separate on/off switches, where the 3 switches worked together as a group. In other words, when any of the switches was turned on or off, the other 2 switches would also turn on/off simultaneously. It worked well for >15 years until a lightning strike disabled my home controller and a couple of the switches, etc., so I've been on a journey to replace the entire system.
I've experimented with a Z-wave based solution, but the synchronization has proven quite unreliable (90% of the time the Z-wave switches sync, but 10% of the time they don't ... ugh).
My key question: can Caseta switches be paired / grouped to work in sync? And how is this done? (BTW, dimming is NOT needed.) I've been looking on the Lutron forum and through other Lutron documentation, but haven't found the solution that matches my use case (again, this is NOT a 3 way / 4 way use case - each floodlight is on a separate circuit controlled by a separate switch).
Assistance is greatly appreciated, would like to have some degree of certainty that I can group the switches together before plunking down $$$.
