A tiny Zigbee wireless relay that doesn't require a neutral wire – ideal for making your existing light switches and other devices into smart, remote-controlled ones!

Introducing the Sonoff ZBMINI Extreme Zigbee Smart Switch, the smallest Zigbee wireless relay designed for seamless light control without needing to swap out your existing bulbs. Compact, clever, and easy to install, it’s the perfect solution for upgrading your lighting while keeping things simple.

Need a neutral wire? Try the Sonoff ZigBee Smart Relay (With Neutral).

To use Zigbee devices, you’ll need a Zigbee-compatible USB dongle connected to an always-on computer (a Raspberry Pi works perfectly!) or a dedicated smart home solution such as the excellent Home Assistant Green (with Zigbee dongle) or the Sonoff iHost.

What Is Zigbee?

Zigbee is a wireless standard enabling low-power, secure connections between smart devices. Widely used in home automation for devices such as thermostats, sensors, and locks, its energy efficiency allows some devices to operate for years on a single coin cell battery.

The key advantage of Zigbee is its local nature – no need for cloud subscriptions or even an internet connection. Everything can stay within your home, ensuring high security and resilience against internet outages.

Top brands like IKEA, Philips Hue, Tuya, and Sonoff offer Zigbee-supported devices. This allows you to combine products from various manufacturers into one smart home setup, ensuring you’re not locked into a single vendor – brilliant!

With an indoor range of 10–100 metres and extended outdoor coverage, Zigbee’s mesh networking ensures reliable communication, even if some devices go offline. Robust security features, including encryption and key protection, safeguard your smart home and keep it under your control.
