    DC:OR USB:USB Power Adapter for the Zooz ZEN16 MultiRelay


    We challenge you to find more bang for your buck! The Zooz MultiRelay combines two 15 A dry contact relays and one 20 A relay so you can cut down on hardware and stay on budget. This device is your answer if you want to control 3 garage doors with a single unit (pair it with a Z-Wave tilt sensor to monitor open/close status of your door). Zooz even has a dedicated Garage Door Opener app for Hubitat and easy to follow steps for SmartThings, making the programming part quick and easy.

    If you’d like to automate your gas fireplace, pool pump, or commercial gate, the MultiRelay is capable of all of it and more. Use the MultiRelay to manage your sprinkler system via Z-Wave and connect it with the ZAC98 accessory relay to use your existing sprinkler timer as a trigger. Better yet, create custom if/then rules with your Z-Wave hub to trigger different events and scenarios, like having your sprinkler system turn on once your garage door closes in the morning.

    Mount it on your wall using the built-in inserts, and connect wall switches if you’d prefer physical control of the connected devices. The MultiRelay is equipped with the latest S2 security protocol for secure connections and its Z-Wave Plus chip ensures fast and stable communication with your Z-Wave hub.


    Follow the appropriate diagram to wire the MultiRelay according to your application. If you don't see a diagram describing your set-up, please contact us to request help with the installation. Remember to always turn power off at the breaker before handling the wires. Never apply any voltage to the Sw input terminals!

    Once you've completed the wiring, power the MultiRelay up with a USB C and a standard power adapter (sold separately) or a direct connection to 12 / 24 V power source (remember about polarity if using DC voltage).

    Now add the MultiRelay to your hub: initiate inclusion (pairing mode) and click the Z-Wave button on the device 3 times quickly. The LED indicator will blink to indicate communication and stay on for 2 seconds to confirm inclusion.

    You’ll most likely see 4 new on/off devices in your app:

    3 channels for on/off control of each relay
    1 master node to control all relays at the same time and to access and adjust advanced settings in (if your hub supports parameter input)


    TRANSLATES LOW-VOLTAGE SIGNAL FOR ZEN16 DRY CONTACT INPUT TERMINALS (Great for alarm system or sprinkler timer triggers)

    Zooz 2 Channel NO & NC Accessory Relay

      Automate your gas fireplace

      Got 2 of these to put my gas fireplaces into Home Assistant. Hardest part was finding spade plugs and creating a couple of pigtails so I wouldn't have to cut any existing wiring. The installation instructions are spot on and they installed in about 5 minutes. They also included into my Zwave network the first time, which is a rarity for me. It's nice to be able to get a fire going before heading home from dinner.

      Good Relays

      Relays worked once I figures out how to utilize them in my system and got online to find out how to set them up in my system.

      Great Multi-Use Relay!

      Using it for my garage door opener - works perfectly!

      Perfect for my Gas Fireplace and Awesome Support

      Purchased this multirelay for my gas fireplace. It is installed with a millivolt natural gas controller and 120volt blower fan. I was able to connect both of these two the relay and use Home Assistant & Alexa to power them on. Also setup a timer off as the wife and kids would leave it on. Awesome device and works like a charm. I’d recommend this to any tinkerer/Dad/smart home geek.

      I previously had a dead on arrival and after some initial troubleshooting, they agreed to replace it. Thanks Zooz support!

      Great Versitile Relay

      I used four of these to build a sprinkler controller under Hubitat in combination with the "switch scheduler and more" user created application. The combination has worked very well with over two weeks of service. The large number of configuration options for these relays really allows your imagination to be the limit to what you create.
