Sonoff MINI-ZB2GS-L (Mini Duo-L) Smart Switch, 100-240V AC, max. 12A, 2-channel, Zigbee 3.0 (No Neutral Wire Required)  SONOFF smart home system allows you to control your electrical appliances remotely with the EWeLink app or by voice with Amazon Alexa or Google Home. It allows you to create different scenarios, group appliances by switching on/off multiple devices with a single touch, set timers and schedules, monitor the status of your devices in real time, and share their control. By linking the eWeLink app with the IFTTT automation platform, you can further expand automation possibilities.  Features:  Sonoff MINI-ZB2GS-L is designed to turn an existing wall switch into a smart switch. It is a dual-channel relay module that operates using only the live wire and does not require a neutral wire, making it particularly suitable for upgrading older electrical installations. Two independent channels support up to 12A total load and allow separate control of two devices or lighting circuits, providing greater flexibility for everyday use. The smart switch is easy to install and can be remotely controlled using the eWeLink mobile app (Android, iOS). It supports smart features such as voice commands, timers, schedules, group control, and automation scenes. Built on the global Zigbee 3.0 standard, it ensures seamless compatibility with popular Zigbee ecosystems, stable connectivity, and low power consumption. It easily integrates with Home Assistant and other open-source platforms, allowing users to create customized smart home control systems (for example, via SONOFF Dongle Series USB adapters, sold separately). Using Matter Bridge, SONOFF Zigbee devices can be integrated into the Apple Home ecosystem and controlled together with other smart devices. When paired with a set of two-way switches, it allows lighting to be switched on or off from multiple locations, such as controlling stairway lighting from both the top and bottom of the stairs. Supports Detach Relay Mode, allowing the external switch and relay to operate independently. Smart control via the app or automation remains available regardless of the wall switch status, while physical switch control remains active even if the network connection is lost. Supports voice control via Google Assistant and Amazon Alexa. Easy to install and operate. Its compact size allows installation even in small EU-type, 86-type, and 120-type wall boxes. Made of V0-rated flame-retardant PC material. The switch can be integrated with various other products to enhance smart home automation scenarios. Note: A Zigbee hub is required for operation.
