    The Zooz Z-Wave Plus Range Extender uses 800-series Z-Wave to expand your network to the farthest reaches of your property. With a range of up to 400 feet, use it to connect tough-to-reach spots to your Z-Wave hub, like outdoor sensors whose signals may be shortened by thick walls, glass, and metal elements.

    Use it to give your smart door lock a boost if you’re having trouble keeping it online. Add it between your hub and devices in outside structures for more thorough monitoring and control. Or simply install it in an area with any far-away or older generation Z-Wave device to stabilize connectivity depending on the specific structure of your home and layout of your network.

    Just plug it into a standard receptacle and add it to your Z-Wave hub for an instant power boost. And if you lose power, the device will send an alert to the hub thanks to its built-in back-up battery. As a 800 series device, it comes with the latest advancements to the Z-Wave protocol and includes S2 secure SmartStart technology to ensure your network remains secure. 


    Set up couldn’t be simpler. Choose the receptacle you’d like to use to power the Range Extender. Once plugged in, put your Z-Wave hub into inclusion mode. Refer to your hub’s instructions to initiate inclusion as every hub is different. Once you see the hub is looking for new devices, click the Z-Wave button 3 times quickly. The LED indicator will
    start flashing green to confirm inclusion mode and turn green for 2 seconds once inclusion is completed.

    Once the device is included to your hub, no additional programming is needed. Regardless of how the device displays, it will begin repeating Z-Wave signals upon inclusion. We just recommend that you refresh your network so that the hub can find the most efficient path to each device with the Range Extender included. For the advanced functionality of power outage reporting, your hub needs to support the device's additional features. See the Works with section below for details.

    Zooz 800 Series Z-Wave Plus Range Extender ZAC38

    Extremely easy to install and configure for Home Assistant. Drastically improved response time for devices in second building after rebuilding routes.

    A good substitute when working with a less powerful hub

    Installed and it did improve my network, but swapping to the new C8 Pro hub made an even bigger difference. Still use it and it still functions as a crucial central node in my Z-wave network

    Works great on Hubitat to monitor power

    I purchased one of these and am using it on a Hubitat C-5 hub. It works great. If the power goes out, I get notified on my phone and Alexa. If it stays out for longer than a minute (meaning the generator didn't kick in and it wasn't just a momentary glitch), a battery siren will sound to let us know if we're sleeping.

    Good product

    I use it as a signal buster and trigger to get notified when power goes off

    Great little dongle

    I couldn’t be more pleased. Ordering and shipping was straight forward. The dongle was straight forward to set up. Everything worked as it should. Definitely recommend for anyone needing to implement Z-wave.
