    How to include the 800 Series S2 Dimmer to your smart home hub?

    1. Make sure the dimmer is located within range of your Z-Wave network
    2. Put your Z-Wave controller in inclusion/pairing mode
    3. Tap the upper paddle of the dimmer 3 times quickly to finalize the inclusion process
    4. A new dimmer switch will appear on your controller's device list

     NOTE:  Follow an appropriate diagram from the manual to wire the dimmer in a 3-way or 4-way setting with a regular on/off electrical switch if you are looking to control one light with 2 or 3 switches. If you can't match your wiring with any of the diagrams, let us know and we'll walk you through the wiring process.

        Very smooth controls!

        I had difficulty with having the ground wire stay put in the switch during the installation process. Overall, the switch feels quite sturdy after installation and the controls are quite smooth with little delay when issuing commands from a Z-Wave hub!

        has all the features I'd want

        I particularly appreciate being able to configure ramp rates. Haven't been able change the indicator color - I don't really care but it's strange that there's a setting for it

        Works well but not recommended

        I would not recommend this switch. I think it's easier to rewire 2nd switch and use the regular dimmer. Also, it doesn't support momentary switch, I believe.

        The 2nd switch has delay when switching, support suggested to update but I haven't got to it. When switching the 2nd switch, there's like 1 second delay and it's really confusing for people.

        Hi Kamil!
        Thank you for your feedback! The ZEN77 was created specifically for simpler installation in 3-ways with a standard mechanical switch on the other end. The ZEN77 allows you to install the smart switch without rewiring the second box in the installation; due to this unique, patented design it cannot be used with a momentary switch on the other end of the installation, as noted on the device page and in the device manual. The delay you noted is resolved with a simple firmware update. Please let us know if you have any questions!

        Easy to install, works perfectly!

        This switch was easy to install, especially with the great documentation. Additionally, after install it added perfectly to my Home Assistant hub which then even offered to correctly upgrade its firmware. It works right out of the box, but also there are so many great customization options that are available. I'm so pleased with my decision to buy this!

        Good Z-wave switch and amazing supoort.

        My first Zen77 was a defect but The smart house was quick with the replacement. The replacement installed and works with Home assistant without any problem.
