I am looking for a smart dimmable 3-way switch (to replace a "dumb" dimmable 3 way switch). It seems these are few and far between ... however, my searches keep suggesting Caseta. However, I am really confused why a 3-way dimmable Caseta even exists. Isn't a single-pole dimmable Caseta switch + Pico remote the just exactly the same thing as a 3-way + Pico? Or does a Pico not communicate to a single-pole?If I'm going to be capping off the wires at the remote end of my existing 3-way set-up, then can't I just use a single-pole smart switch? Are ALL switches essentially 3-way (or multiple-way) if the are remotely controlled (via app or Pico)?Can someone please help me understand the difference?Thanks (and sorry if this is a stupid question!)
