Product detailed description

⚡️ Sonoff Zigbee Smart Switch EXTREME R2 (Neutral Wire Required)

The SONOFF ZBMINI R2, also known as the Sonoff Zigbee Mini Extreme, is a compact smart relay module that communicates via the Zigbee 3.0 protocol and is designed to be installed in a junction box behind a wall switch. It supports remote control and adds smart functions to existing traditional switches, providing both convenience and flexibility. Due to its compact design, it can be installed behind a switch or push-button. It requires a Zigbee-compatible gateway or controller for smart control and smart home integration.

SONOFF ZBMINI R2 is the Zigbee version of the popular compact relay switch by Sonoff, which can be installed in wall junction boxes or directly behind a switch. Released at the end of 2024, this small, compact smart relay module communicates using the Zigbee 3.0 protocol. It is an ideal choice for those looking to modernize their home lighting or remotely turn on other household electrical appliances. With this device, any circuit can be integrated into a smart home system that supports Zigbee 3.0 communication. The Zigbee MINI Extreme R2 not only allows for remote control but also adds smart features to traditional switches, offering convenience and flexibility. Thanks to its compact design, it is compatible with most types of switches, so replacing old, traditional switches is often unnecessary. The ZBMINI R2 requires a Zigbee-compatible gateway, bridge, or coordinator for remote control and smart home integration.

What is Zigbee?

Zigbee is a protocol specifically designed for smart home/IoT applications, developed for efficient communication between such devices. Unlike Wi-Fi devices that connect directly to a router, Zigbee devices require a Zigbee-to-Wi-Fi gateway (also called a bridge, hub, or coordinator) for remote control and internet connection. One advantage of Zigbee solutions is that they offload traffic from your Wi-Fi network, as only one Wi-Fi device (the Zigbee gateway) connects to the router, while all other devices communicate via the Zigbee protocol, freeing up router IP addresses.

Zigbee technology also supports mesh networks, where 230V powered Zigbee devices (such as the Sonoff ZBMINI and Sonoff Basic ZBR3 relays) can transmit data from other Zigbee devices to the Zigbee gateway if they are out of its direct range, thus expanding the network's coverage.

Another advantage of the Zigbee protocol is its low power consumption, which is much lower than Wi-Fi. This makes the Zigbee protocol particularly popular for battery-powered sensors, which can operate for years on a single battery due to their low power requirements. Zigbee handles only small data packets, which is usually sufficient since it is mostly used for control commands and status updates. The Zigbee protocol is an industry standard, so fully standardized Zigbee devices should theoretically be compatible with standard devices from any manufacturer.

Technical Specifications Sonoff R2

The ZBMINI R2 is a 230V relay switch that connects to the mains on one side (L and N) and can control a 230V load on the output side, allowing it to switch the circuit on and off. It can be installed behind sockets or switches (maximum load: 10A). An external switch can also be connected to its input, allowing both the wall switch and the Zigbee app to control the device when installed behind wall switches. Thanks to an internet connection and the SmartThings app on an iOS or Android phone, or when connected to the Sonoff Zigbee Bridge Pro via the eWeLink app, the relay can be controlled remotely.

Compatibility and Integration

The ZBMINI R2 is compatible with several Sonoff Zigbee-to-Wi-Fi gateways, including Sonoff Zigbee Bridge Pro, Sonoff Zigbee Bridge Ultra, and NSPanel Pro. Once connected to one of these, the ZBMINI R2 can be controlled using the familiar eWeLink platform and app. Typical eWeLink functions include current ON/OFF status, manual ON/OFF switching, and timers (schedule, countdown, loop control), but the inching (pulse switch) function is not available. It is also compatible with Sonoff iHost and the SmartThings system, and can be controlled using the SmartThings app, available for both iOS and Android. The SmartThings app offers features such as remote ON/OFF control and scheduled ON/OFF, among others. 

The ZBMINI R2 also works with the Amazon Alexa platform (compatible with devices like ZE39KL Echo Plus, Echo Studio, DW84JL 2nd Gen Echo Show & L9D29R 2nd Gen Echo Plus) and can be paired via Alexa voice control by saying "Alexa, discover devices."

The ZBMini R2 is compatible with the following Zigbee gateways, among others:

🌐 Sonoff Zigbee Gateway: Sonoff Zigbee Bridge Pro, NSPanel Pro, and ZBMini R2 can be connected to one of these gateways and controlled via the familiar native eWeLink platform and app.

🌍 It is also compatible with the SmartWise Zigbee Bridge Pro gateway, which also supports an ethernet connection and uses the eWeLink app.

🔗 It can be paired with the Sonoff Dongle Plus E Zigbee coordinator, as well as with other standard Zigbee coordinators (e.g., Conbee II, Conbee III).

🏠 Compatible with Sonoff iHost, which offers local control independent of the cloud and Zigbee gateway functionality.

🔄 When used with the Sonoff Zigbee Bridge Ultra, it is compatible with Matter-compatible smart home systems, including Apple HomeKit.

📱 SmartThings hub, controlled via the SmartThings APP available for iOS and Android. In the SmartThings app, features such as scheduled turn off/on and many more are available.

💡 Compatible with the Philips Hue hub.

🔊 Amazon Echo Plus 2nd, Echo 4th Gen, and Echo Show 2nd gen.

⚡ So the ZBMini R2 is a 230V switching relay that connects to the mains (phase and neutral) on the input side and can be used to control a 230V appliance, closing and opening the circuit on the output side. It can also be installed behind sockets and light switches (max. output 10A).

An external switch can also be connected to the switch input, so it can be placed behind wall switches and toggled from the wall switch (both push-button and rocker switches), and of course, control and integration via the Zigbee app work flawlessly.

On a mobile phone running iOS (Apple) or Android connected to the internet with the SmartThings app (for a SmartThings hub) or connected to the Sonoff Zigbee Bridge Pro, you can remotely control the switch relay using the eWeLink app.
