The SONOFF Orb-ZBW2L (MINI-ZB2GS-L-E) is an ultra-compact, phase-only, dual-channel Zigbee 3.0 smart relay module with a wall switch, with which you can replace your existing light switches with an elegant yet modern piece. The switch fits into a standard junction box and can control two independent lighting circuits. Total max. It offers a load capacity of 16 A (max. 10 A per channel, resistive load), with timings, scenes and group control.

The built-in Zigbee signal amplifier/repeater function of SONOFF Orb-ZBW2L (MINI-ZB2GS-L-E) improves the stability of the network, and thanks to the external wall switch, the usual manual control is also maintained. It is compatible with popular platforms (e.g. Home Assistant - ZHA/Zigbee2MQTT -, Alexa, Google Home, SmartThings), so it can be integrated into a unified smart home.

It is an ideal choice for renovation and retrofitting, when you want to control two separate circuits discreetly, with a module placed in the wall with a modern light switch - quick installation and reliable Zigbee connection.

Main product features

- Double channel, compact design: control of two independent circuits from a single module that can be recessed into the wall.
- Reliable Zigbee 3.0: fast pairing, stable network; built-in Zigbee repeater to improve network quality.
- External switch support: also works with rocker and push-button wall switches; the switch type can be changed with the button of the module.
- Timing and scenes: schedules, group control, smart scenes for convenient automation.
- Power-On State: behavior after a power failure can be set (ON/OFF/last state).

Smart home protocols and platform compatibility

- Protocol: Zigbee 3.0 (IEEE 802.15.4).
- Compatible gateways/platforms: SONOFF ZBBridge-P/-U, NSPanel Pro, iHost, ZBDongle-P/-E; also works with Home Assistant ZHA and Zigbee2MQTT integration.
- Voice control and ecosystems: Amazon Alexa, Google Home, Samsung SmartThings (depending on the hub).
- Local automation: scenes and rules in a Zigbee hub; the module's LED and button help with pairing and status indication.

Smart functions

- Remote ON/OFF and status query: control and feedback from app/hub.
- Schedules and timers: time-based switching adapted to daily routines.
- Scenes and groups: coordinated control of several devices (e.g. room level switches).
- External switching modes: push button/rocker selection; can be changed quickly by pressing the button three times.
- More advanced settings (Zigbee2MQTT): available, among others, detach relay mode, external trigger mode, pulse switching (firmware/hub dependent).
