    Design Features

    • QuickFit™ — improved components reduce housing depth by up to 20% compared to previous Wi-Fi models, and eliminate the need for heat tabs.
    • SimpleWire™ — auto line-load sensing terminals support fast installation by detecting line and load wires and configuring the dimmer accordingly. Dual ground ports (offset to avoid switch-box mounting screws) support daisy-chaining in multi-switch setups.
    • Can be included in multiple Groups, Scenes, and automations.
    • Operates in either switch or dimmer mode.
    • Double-tap and triple-tap scene activation directly from the device.
    • Set upper and lower brightness levels to eliminate bulb flicker.
    • Turn the device on/off manually or adjust brightness with the JascoPro™ Series App.
    • Single-pole installation, or use with up to four Jasco model 46560 Add-on switches in 3- or 4-way connections (traveler wire required for multi-pole installation), or connect with an existing 3-way switch.
    • Works with all LED, CFL, halogen, and incandescent bulbs.
    • Blue LED indicates automatic/manual pairing mode status, and can indicate switch location in a dark room (4 adjustable brightness settings).
    • Uses a standard Decora wall plate (not included).
    • Interchangeable paddle switch — white and light almond paddles included in the package.
    • LED status can be manually inverted, always-off, or always-on.
    • Inline traveler circuit protection.
