Smart adapter Sonoff ZBMicro USB ZigBee switch, max 36W, ZigBee control for USB-powered devices

Smart adapter USB ZigBee switch SONOFF ZBMicro (max 36W). SONOFF ZBMicro is a Zigbee USB adapter designed to add remote and automated control to USB devices in a smart home. It supports app integration for schedules and scenes, voice assistants, charging of connected devices (using a separate fast charger) and functions as a Zigbee signal extender. Note: a Zigbee hub is required for operation (hub not included).

Advantages

Provides fast charging of up to 36 W when used with a compatible QC 3.0 or other supported fast charging adapter, improves USB data throughput via Hi-Speed USB 2.0, and converts ordinary USB peripherals into controllable smart devices. Acts as a Zigbee router with Turbo mode to strengthen network coverage and is compatible with a wide range of hubs and open automation platforms. The compact plastic housing is made for indoor use and is simple to set up through the eWeLink app.

How to use

Plug the SONOFF ZBMicro into a USB power source and connect your USB device to the adapter. Add the adapter to a Zigbee hub that supports Zigbee 3.0, then install and open the eWeLink app to follow the pairing and configuration steps. After pairing you can set schedules, create scenes and enable voice control through compatible assistants (Amazon Alexa, Google Home, Alice) or integrate with platforms such as IFTTT, SmartThings, Home Assistant, Zigbee2MQTT or openHAB. To use fast charging up to 36 W, connect a compatible QC 3.0 (or other supported) fast-charging adapter to the power source; the ZBMicro itself does not generate fast charge without such an adapter.

Recommendations

Use the adapter indoors within the specified temperature and humidity range. For reliable Zigbee coverage, place the ZBMicro between the Zigbee hub and other Zigbee devices to act as a router and enable Turbo mode if needed. When fast charging, use a certified QC 3.0 or compatible adapter and avoid prolonged charging beyond the device manufacturer's recommendations to protect battery life.
