Z-Wave Dimmer Switch + Repeater


Wire up the Switch. Sync. Control Lights Manually & Remotely.

Control your lights in your smart house with the Inovelli® Z-Wave Plus in-wall smart switch. In addition to being able to remotely control your devices, this smart switch also acts as a Z-Wave signal booster (repeater), giving you best of both worlds and can also be wired using your existing 3-Way setting in that you won’t need to purchase any auxiliary (add-on) switches.

Easy 3-Way

These switches will work in an existing 3-Way setup. No need for an, “add-on” switch.
Simply wire these up to a, “non-smart” (On/Off) switch and you’re good to go. See our wiring diagrams for more info.

Manual & Remote Controllable

Turn on/off lights manually (up = on // hold up = dim up // down = off // hold down = dim down) or remotely. Set schedules, or trigger an event… the power is yours!

Show Home and Inovelli Smart Plugs are Z-Wave Plus Certified

Z-Wave Plus

Our NZW31 Z-Wave Switch is certified Z-Wave Plus, making it one of the few on the market to really take Z-Wave seriously. With a built in signal repeater, this smart switch is really a cut above the competition.
