I have two mechanical 3-way switches, where a neutral wire is NOT present. I do not want a dimmer switch -- just a 3-way on-off switch. I'm guessing only one of the two switches needs to be a wireless smart switch (but please correct me if I'm wrong). I need this to be compatible with Apple Home.
What do I need to purchase to support this configuration? Do I need two smart switches and a smart hub (I don't own any Lutron Caseta products yet)? Or can I purchase only one smart switch and a smart hub -- and use my existing mechanism 3-way switch?
Thanks much. -- Eric
