The Enbrighten Zigbee wall dimmer switch works with Zigbee smart home hubs to provide local and remote on/off and dimming control of dimmagle lights. The rocker design is intuitive - press top for on, hold the top for brighten. Press the bottom for off, hold the bottom for dim. This Zigbee 3.0 dimmer is compatible with a wide range of smart home hubs and supports voice control integration via the hub. It is also directly supported by Amazon's Echo Studio, Echo Show 10 of Echo Plus. SimpleWire technology makes it faster to install. It auto-detects line and load wiring. The QuickFit feature means it's easier to fit in standard wall boxes due to a smaller size.
