Main Features

Detach Relay Mode: Separates the physical button from the electrical circuit — ideal for smart bulbs that remain powered even when the switch is “off,” allowing continuous control via app or voice.

Zigbee Router Function: When connected with a neutral wire, it extends the Zigbee network coverage as a signal repeater.

Local & Remote Control: Turn on/off via button, app, voice, or automated routines.

Smart Automation: Schedule lighting based on time, brightness, or triggers from sensors.

Modern Design: Sleek minimalist white finish, part of the SONOFF SwitchMan series.

Applications

Home users: Convenient lighting control via phone or voice; create “Night,” “Away,” or “Home” modes.
