Sonoff MINI-ZB2GS-L ZigBee two-channel mini switch without NSonoff MINI-ZB2GS-L allows you to turn a traditional switch into smart lighting control – without the need for a neutral wire. It works particularly well in older installations where there is only a phase wire in the junction box. It is small in size, supports two circuits, and works with popular ZigBee gateways.Works without a neutral wireThe model works without an N wire, so you can modernize your installation without chiseling walls or making electrical modifications. Installation is simpler and faster, and you save time and money associated with installing additional wiring. The module does not require an additional bypass, which facilitates installation and reduces the number of components in the system.Two channels – independent controlMINI-ZB2GS-L supports two outputs (L1 and L2), allowing you to control two independent circuits, such as two lighting sections. Each channel can operate separately, giving you greater flexibility in arranging the lighting in the room. The maximum load is 8 A per channel, up to 12 A in total, which is suitable for typical home applications.Compact size and 60 mm box installationThe housing, measuring approximately 45 × 39.4 mm, is designed to fit easily into a standard 60 mm diameter installation box. Its small size makes it easy to install behind a traditional switch, even with limited space for wiring. This allows you to keep your existing wall fixtures while expanding their functionality with smart control. The device works with various types of switches, including SPDT, allowing you to adapt it to your existing installation.Integration with gateways and system functionsThe module operates on the ZigBee 3.0 standard and requires a ZigBee gateway. It works with iHost, NSPanel Pro, Zigbee Bridge Pro, Zigbee Bridge Ultra, Dongle Max, ZBDongle-P/E, Dongle Plus MG24, and Dongle Lite MG21, among others. This allows you to easily adapt it to your smart home infrastructure. Once integrated with the system, you gain full control over functions such as remote switching on and off, changing the operating mode of the external switch, disconnected relay mode, or setting the status after power restoration. OTA updates are also available, allowing you to keep the device up to date with the latest software without having to disassemble it.Disconnected relay mode and automationThe relay disconnect function allows you to transform a classic switch into a smart scene control button. In practice, this means that physically pressing the switch can trigger a specific action in the smart home system without directly switching the power. You can set schedules, timers, and create smart scenes. The event history also allows you to control when and how the module was used.Included Two-channel mini switch User manual Manufacturer Sonoff Model MINI-ZB2GS-L Series MINI Extreme series Communication standard ZigBee (IEEE 802.15.4) Supply voltage 100–240 V ~ 50/60 Hz Maximum load 8 A per channel, total max. 12 A (resistive load) Minimum load 3 W, operation without neutral wire (The power of the connected light source must exceed 3 W.
