Backstage Z-Wave

PRODUCT HIGHLIGHTS

  • On/off Z-Wave control for 120V and dry contact applications: great for lighting control or 120V load monitoring (sump pumps, motion lights)
  • 700 series Z-Wave chip: greater coverage for a stronger mesh network
  • Long Range: if your hub implements Z-Wave Long Range, you'll benefit from the latest direct device-to-hub communication which extends the range like never before and eliminates network lags (note that versions for regions outside of US/CA/MX don't come with LR)
  • SmartStart and S2 authenticated security for a truly protected smart home
  • Installs behind the existing wall switch or at the fixture (if neutral is not available in the switch box)
  • Pigtail wires included for hassle-free set-up
  • Perfect if you'd like to leave your favorite wall switch style or color but add Z-Wave to it
  • Smart bulb mode: disable manual and/or Z-Wave control to control your smart bulbs via Z-Wave only without cutting power to them
  • Scene control: choose from 7 multi-tap triggers to expand the functionality of the connected switch (available on hubs that support multi-tap triggers*)
  • Multicolor LED indicator for easier pairing and diagnostics
  • Compatible with quality LED and incandescent bulbs (don't connect to ballast tube lights, switched receptacles, or fans over 3A / 5 years old; NOTE: FEIT bulbs are not recommended)
  • Built-in signal repeater: helps keep your network quick and reliable
  • 5-year warranty and lifetime tech support

    NOTE: Z-Wave gateway controller required - sold separately. *Your smart hub / controller needs to support advanced settings and central scene programming for you to take advantage of this feature.

    • OPEN BOX: like new item in excellent condition, it may come in partially damaged or not original packaging; all accessories included; hardware and firmware version may be different than the brand new device description, may not feature Z-Wave Long Range.
    • REFURBISHED: good condition, may show slight signs of wear, may not include all accessories (like product manual, battery may not be full, etc); hardware and firmware version may be different than the brand new device description, may not feature Z-Wave Long Range.
    • USED (FINAL SALE): used condition, may show signs of wear, may not include accessories (like product manual, batteries, or mounting hardware) or parts of the packaging; may show signs of wear like scratches; FINAL SALE: not eligible for return, replacement, or warranty service; hardware and firmware version may be different than the brand new device description, may not feature Z-Wave Long Range.

    Z-WAVE FREQUENCY

    This product is available in different Z-Wave frequencies so please make sure you choose the correct region before checking out. You need to select the same frequency / region as your hub when buying Z-Wave devices for them to include to your system. If you're not sure which frequency your hub operates on, please contact your solution provider first. Here is what each option stands for:

    • US/CA/MX: 908.42 MHz (used primarily in US, Canada, and Mexico, the default option for all products)
    • EU/UK: 868.42 MHz (used primarily in Europe) - no Z-Wave Long Range

    INSTALLATION

    Before installing, make sure the load does not exceed 960W for incandescent lights, 150W for LED's, 3A for fans and motors, or 10A for resistive load. Check your wiring first to confirm that you have all the following wires present in your gang box: load (most often black), line (most often black), neutral (most often white), and ground (most often green).

    If you are not comfortable identifying the wiring and following the instructions, please hire a licensed electrician.

    Zooz 700 Series Z-Wave Plus Dry Contact Relay ZEN51 Single Pole Wiring Diagram

    Here are some helpful wiring tips:

      • Make sure the gang box you are about to install the switch has a neutral wire available - you will not be able to get the ZEN51 relay to work without a neutral wire. If neutral is not available, you'll need to install the ZEN51 at the light fixture.
      • Unlike regular mechanical switches, Z-Wave switches require all of the wires to be connected exactly as indicated - line and load wires can never be swapped as it sometimes happens to the most experienced electricians.

    How to include the Dry Contact Relay to your smart home network?
    1. Bring your Z-Wave gateway hub or controller as close to the switch as possible
    2. Put your Z-Wave controller in inclusion/pairing mode
    3. Click the Z-Wave button on the relay 3 times quickly to finalize the inclusion process
    4. A new on/off switch should appear on your controller's device list

      Excellent Support

      Had wiring issue that support addressed immediately and accurately. In fact, they did much more than I expected. They went so far as to annotate the necessary configurations on the diagram that I provided them. The product itself is very good. Having such good tech resources makes all the difference.

      Extremely unimpressed

      I've had these for about 8 months, and frankly, they suck. I bought them to go behind regular switches because (dumb) reasons.
      - They are smaller than a full-sized smart switch, but not really smaller than a normal switch plus the relay. Meaning, it is no easier to install than a regular smart switch.
      - There is no physical access to them once installed. To do any sort of reset, you need to remove everything because the relay ends up in the back of the box.
      - So far, I've had to replace one that completely stopped responding (in 6 months)
      - Since there is no physical way to power cycle the device, I've had to power cycle the entire circuit the device is on to fix issues where it just stops responding.
      - It stops responding to both flipping the switch and doing anything remotely using the Hubitat.
      - I've had to do this at least 6 times. Do you know how annoying it is to have to go to the circuit breaker and flip 10 lights off and on to fix one stupid switch? I do!

      During this time the physical Zoos switches I have on the same circuit and with the same setup (some 3-way, some normal) have had no issues, so its likely not my house's electrical system failing. However, even if it is, I don't care, because I didn't install these so they could fail in 6 months for ANY reason.

      Buy a normal switch. Zoos makes some decent ones. Inovelli makes some decent ones too. Just don't by the relays unless you are ready for issues, or have no other choice.

      Thank you for your feedback, Michael! As noted in the documentation for the device, exclusion and inclusion can be easily done via the connected switches. We would be happy to troubleshoot your installation if you would like to reach out to us with the specific details of your installation!

      Worked Pefrfectly

      I purchased these to add to some tap lights I have in wall receptacles. The lights are supposed to turn on when the light dims to a low level but they are in a hallway that does not get much light at all, so they are on all day. I added these to set up a routine to have them turn on only after sundown. They work perfectly. I will purchase again for other applications.

      Works well with HomeAssistant

      I bought two of these. I'm using them to monitor my power grid for outages. They work surprisingly well with HomeAssistant. No issues with pairing.
