Home automation is the residential extension of building automation.

It is automation of the home, housework or household activity.

Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, security locks of gates and doors and other systems, to provide improved convenience, comfort, energy efficiency and security.

Analog switches adding smart capabilities (alien.top)

Hey everyone, doing some renovations and thinking about future pieces. Basically plan to be putting can lights in the living room and have 3-way switches on either side of the room. Ideally I’d be able to keep that analog setup but add control of the lights using some kind of controller. I’d prefer the controller not rely on Wi-Fi for control, Ethernet or similar would be best. Anyone point me in some direction of research and/or products to look at?

A couple options:

Install smart 3-way switches (or dimmers) using ZigBee, Z-Wave or Matter protocols instead of the dumb "analog" switches. You'll need a smart hub that acts as the centralized controller. The switches still handle on/off at the wall (or dimming if you want that as well), but you can use voice control or routines to adjust them.

Add smart relays behind the switches. I believe Zooz has some smart relays that use Z-Wave. Again you'd want a hub that can talk Z-Wave. There are Wi-Fi versions like Sonoff or Shelley, but you said you want to avoid that.
