I’m new to SmartThings, looking to change from an Insteon setup with ~10 light switches over to a more modern and less fragile technology. A core setup that I have been doing with Insteon is 3 separate physical dimmers in a living room that each switch a circuit of recessed lights. In insteon I grouped these switches together that each one of them would switch all 3 circuits together on and off. I also had the option with a remote to individually switch the circuits on and off.
Is this possible with SmartThings/ZWave? What is the lag in such a setup, do all circuits switch simultaneous?
