I've searched purchase material, and online, can't find an answer.
Do BOTH switches in a 1-light, 2 switch 3 way wiring need to be HS210, or just 1?
If I want to control circuit via google/alexa, and the switches, do I replace both switches, and pair them together, or can I replace just 1 in the circuit?
I bought the HS210kit, with 2 switches but now wife would like 2 separate circuits controlled, not sure if I need another kit, or just use an existing non-smart switch on each circuit.
Thanks for help.
