new to all of this. Need rec’s for a wifi light switch. Have some knob & tube in my home; outlets have had a ground wire added to them but pretty sure the switches and lights have not been updated. If there is a neutral: what would you recommend? If there isn’t? I’m wanting to begin with something that’s easy to add to (more products as I get more into home automation). Right now my wishes are to be able to control the lights from an app, set timers, and allow the lights to turn on/off with motion. Thanks!
