The SONOFF Orb-ZBW1L is a Zigbee 3.0 smart wall switch of the Fusion series, without neutral wire, inside which the ZBMini-L2 takes care of the operation. Handles up to 6 A load and allows you to set timers, countdown timers and smart scenes. It is also optimized for especially low-power LED loads (min. 3 W), so it offers a solution that can be easily retrofitted into old junction boxes without an anti-flicker module. The switch can be used both in the SONOFF ecosystem and on open platforms: Zigbee pairing is easy, and it is also compatible with Home Assistant (ZHA/Zigbee2MQTT) systems. The external wall switch (on S1/S2 inputs) preserves the usual manual control, while automation via Zigbee also works.

Main product features

- No-neutral installation: does not require a neutral conductor, ideal for retrofitting older properties.
- LED-friendly design: stable operation from 3 W, without an external anti-flicker module; max. LED load 150 W @ 100 V or 300 W @ 240 V.
- Smart scenes and timing: countdown, schedule and loop timer support.
- Home Assistant compatibility: works with ZHA and Zigbee2MQTT integrations.

Smart home protocols and platform compatibility

- Protocol: Zigbee 3.0.
- Compatible gateways/platforms: Home Assistant (ZHA, Zigbee2MQTT), SONOFF ZBDongle-P/-E, ZBBridge-P/-U, NSPanel Pro, iHost.
- EWeLink ecosystem: Alexa/Google Home/IFTTT/SmartThings integrations are available through cloud connection.
- Zigbee end device (does not work as a router).

Smart functions

- On/Off switching and status: basic switching function and status query.
- Schedules and countdown timer: automatic operation start at specified times/after a period of time.
- Loop Timer: cyclic execution of preset actions.
- Power-on State: specifying the state after a power failure (On/Off/Last State).
- Scenes/automation: trigger other Zigbee devices based on the state of the switch.
- Logging: viewing the history of status changes.
