The SONOFF Orb-ZBW2L (MINI-ZB2GS-L-E) is an ultra-compact, live-wire only, dual-channel Zigbee 3.0 smart relay module with an integrated wall switch — allowing you to replace your existing light switches with a sleek yet modern smart alternative. The switch fits into a standard wall box and can control two independent lighting circuits. It supports a total load of up to 16 A (maximum 10 A per channel for resistive loads), offering scheduling, scene control, and group management.
The built-in Zigbee signal repeater improves network stability, while the external wall switch inputs ensure you can still use familiar manual controls. Compatible with popular platforms such as Home Assistant (ZHA / Zigbee2MQTT), Alexa, Google Home, and SmartThings, it integrates seamlessly into your smart home system.
It's an ideal choice for renovations or retrofitting, where you want to control two separate circuits with a modern smart switch and discreet in-wall installation — with quick setup and reliable Zigbee connectivity.
