The Sonoff MINI-ZB2GS-L-E is a compact Zigbee smart wall switch designed to bring intelligent control to two independent lighting circuits without needing a neutral wire. This makes it a practical choice for upgrading older homes where rewiring is difficult, as it fits discreetly behind your existing wall switches. It operates on a wide input voltage range of 100-240V AC and utilizes the Silicon Labs EFR32MG22 chip to ensure stable connectivity via Zigbee 3.0. Each of the two channels supports a maximum load of 8A, with a total resistive load capacity of 12A. When used with LED lighting, it can handle up to 300W per channel at 240V, or 150W at 100V. To ensure long-term reliability, the device is housed in flame-retardant PC material and features relays rated for approximately 100,000 cycles, alongside built-in protections against overvoltage and overload. Integration is straightforward thanks to Zigbee Simple Setup and binding capabilities, allowing it to work within various ecosystems such as Home Assistant, Zigbee2MQTT, and the Sonoff iHost. This setup is ideal for users who want to automate their home lighting while maintaining the tactile feel of traditional switches, providing a seamless bridge between manual control and smart home automation.
