Zooz 700 Series Z-Wave Plus Smart Relay ZEN51 Installs Behind Wall Switch Or at the Light

SMART RELAY FOR ON/OFF CONTROL: Install this relay to add Z-Wave to the existing wall switch and keep your favorite switch style and color. The relay output is dry contact for your unique applications outside of lighting but note the input (switch) requires 120 V which makes it perfect for 120 V signal monitoring on sump pumps or motion lights. For a dry contact input device, look up ZEN16. 3-WAY COMPATIBLE: Unlike many other smart relays, you can use this device to automate 3-way set-ups as well. Even if you don’t have neutral available at any of the switch boxes, you can always install this relay at the light fixture where you’ll have access to power and neutral. Always follow the wiring diagrams carefully and make any programming changes if needed when installing this relay. EASY INSTALLATION: Pigtail wires for convenient connections. Connect to mechanical on/off or momentary switches only (NO dimmers or electronic / smart switches). The relay is small enough to fit in the most crowded box, just 1.5″ x 1.4″ and 0.7″ deep. NEUTRAL WIRE REQUIRED (check before buying). The device is ETL certified and conforms with North American safety standards. SMART BULB MODE AND MORE: Bring back the switch function to your old switches even when using smart bulbs. The smart bulb mode allows you to control smart bulbs via Z-Wave without cutting power to them when off. Enjoy the new 700 series Z-Wave with powerful features like SmartStart and S2 authenticated security. HUB COMPATIBILITY: This is an advanced Z-Wave device and it requires an updated Z-Wave hub to display correctly. It was tested to work well with Hubitat, Home Assistant (Z-Wave JS), HomeSeer and is compatible with SmartThings.
