    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

        Riding the Z Wave

        These switches are better than any wifi switch I've ever used. Easy to install and setup. Lights dim extremely low and integration with Google home is seamless.

        Works as advertised

        I've installed several ZEN77 dimmers and am delighted that inclusion works promptly with Home Assistant via manual PIN entry (I never tried QR codes). I can't confirm range of 800 series all mine are installed fairly close to my 700 series Aeotec Z-Stick 7 Plus. And it is great that Zooz brand works just find with other Z-Wave vendors (as intended by the Z-Wave standard).

        My single disappointment is that you have to be super careful to not mix your HOT and LOAD wires--this will fry the ZEN77--permadeath. Surely they could add a few diodes or whatever to just make it not work when incorrectly wired. Hence 4 instead of 5. Nevertheless I bought two more after discovering this, but I used my voltmeter to make sure the red wire was really LOAD.

        Fantastic smart dimmer at a great price!

        I had to choose between buying multiple smart bulbs, or multiple dumb bulbs on a smart dimmer connected to Hubitat. Buying the dimmer was by far the most economical. I have now installed 8 of these in total and will order another 5 soon.

        Great product!

        I've installed several of these in my house, and have never had a single problem with them. They work great with my Hubitat hub, and previously worked great with my Samsung SmartThings hub. Great devices!

        High Quality Dimmer with lots of customizability

        This dimmer worked great for my Sylvania br30 dimmable LEDs. Easy to install and easy to setup/configure. Intuitive use with the switch and high quality feel. Hopefully they hold up well over time!
