About This WIRELESS BRIGHTNESS CONTROL: Manual or remote on/off and dimming control from your mobile device or computer (when included to a Z-Wave gateway controller - sold separately. Smart speakers are NOT Z-Wave hubs). Reports status instantly. NEW SIMPLE DIRECT 3-WAY: Patented solution for 3-way and 4-way installations! No add-on switch needed, no need to rewire the other boxes. Just wire the ZEN74 dimmer in the box with direct connection to power (it needs to replace an existing 3-way switch) according to the appropriate diagram. Works with mechanical 3-way switches (DON'T connect to other dimmers) as long as NEUTRAL is present. NEW 800 SERIES MODEL: Just 1.1" deep to easily fit in crowded and shallow boxes. 800 series Z-Wave chip for faster response time and better wireless range boosted by optimal antennae positioning. Long Range ready for ultra reliable direct hub-to-device communication (you need a LR hub to support this). Remembers and restores on/off status after power failure. Do NOT use as direct replacement for the ZEN24 model in 3-way set-ups, always follow the wiring in the manual. WORKS WITH YOUR HUB! Based on the universal multilevel command class - supported by most Z-Wave controllers (does NOT work directly with smart speakers). Lifetime tech support and 5-year extended warranty once registered. CHECK YOUR WIRING FIRST: Neutral wire is required to complete installation! Do NOT use the ZEN74 model as direct replacement for the older ZEN23 or ZEN24 switches - they wire differently in multi-point control set-ups, always follow the appropriate diagram or ask Zooz for help. SMOOTH DIMMING: Improved dimming capability for LED bulbs (scroll down for details, NOT compatible with Luminus, Lithonia, or Feit bulbs).
