ZOOZ keeps things simple with the ZEN52. It’s a double relay smart switch designed to sit behind your existing wall plates, controlling two separate loads independently. If you have a double gang box and want smart control without replacing your switches, this is the solution. It works with standard mechanical switches, not dimmers or other smart switches. You will need a Z-Wave hub.

The ZEN52 handles up to 1.5 amps per channel with normally open screw terminals and copper contacts. It supports 3-way setups, which many smart relays do not. That means you can automate lights controlled from multiple physical switches without rewiring your entire home. Installation is flush mount, so it tucks neatly behind the switch in the box.

One honest limitation: at 1.5 amps, this is for lighting circuits only. You cannot use it for heavy loads like motors or large appliances. It also requires a neutral wire in the box. If your home lacks neutrals, look elsewhere. For standard lighting retrofits, the ZEN52 is a clean, reliable solution that keeps your wall switches looking normal while adding Z-Wave control.
