This sonoff zbminir2 zigbee smart switch review covers the ZBMINIR2, a compact Zigbee 3.0 relay designed for tight spaces. Measuring just 1.68 inches by 0.79 inches, it fits into standard EU-type, 86-type, or 120-type mounting boxes with ease. The device operates as a Zigbee end-device, requiring a separate Zigbee hub for connectivity. It supports two-way control circuits and works with Alexa and Google Home. You can use it to manage lights and appliances, even those as low as 3W, without needing an anti-flicker module. The unit is white and relies on a hub rather than direct Wi-Fi connection.
What stands out
- Extremely compact dimensions of 1.68 x 1.68 x 0.79 inches
- Zigbee 3.0 connectivity for reliable local network control
- Compatible with Amazon Alexa and Google Home for voice commands
- Supports two-way circuit control for staircase or multi-location switching

Who it fits
Good fit for
This switch suits users who have limited space in their electrical boxes, such as those installing in older homes with tight EU or 86-type enclosures. It is ideal for those who already use a Zigbee hub and want to add smart lighting without replacing existing wall switches. The two-way control feature makes it useful for staircases or hallways where you need multiple control points. If you prefer voice control via Alexa or Google Home and want a reliable local connection that works even without internet, this device fits your setup well.
Who should skip it
You should look elsewhere if you do not have a Zigbee hub, as this device requires one to function. It is not a standalone Wi-Fi switch. If you are looking for a simple plug-and-play solution without additional hardware, this is not the right choice. Additionally, if you need direct Bluetooth control or a built-in display, this compact relay does not offer those features. It is purely a control module for your existing lighting infrastructure, not a complete smart home system on its own.
Verdict: The SONOFF ZBMINIR2 is a highly compact Zigbee 3.0 relay that fits tight electrical boxes and works seamlessly with major voice assistants. It is a practical choice for users with existing hubs who need reliable, space-saving smart control.
Key specs explained
Connectivity: Zigbee 3.0
This protocol creates a local mesh network that does not rely on your Wi-Fi router. You get reliable control even if your internet goes down. It uses less power than Wi-Fi devices. Compare this to Wi-Fi switches that may slow down your network when many are added. Zigbee 3.0 ensures devices talk to each other efficiently in a home LAN setup.
Hub Requirement: Zigbee Hub Required
You cannot connect this switch directly to your phone or router. You must purchase a separate Zigbee hub to act as the bridge. This adds a step to your setup but provides better stability. Many smart home ecosystems require a hub for Zigbee devices. Check if your current hub supports Zigbee 3.0 before buying to avoid compatibility issues.
Smart Home Compatibility: Alexa, Google Home
The switch works with voice commands through Amazon Alexa and Google Home. You can turn lights on or off using your voice after linking the device. This allows for hands-free control in any room. Compare this with proprietary apps that only work with one brand. This broad compatibility lets you include the switch in an existing multi-brand smart home routine.
Circuit Type: Two-way
This feature allows you to control the connected device from multiple locations. You can use external switches like push buttons or rockers alongside the smart app. This is ideal for staircases or hallways where you need control from both ends. It mimics traditional wiring setups but adds smart scheduling. You retain the convenience of physical switches while gaining remote automation capabilities.
Dimensions: 1.68 inches by 0.79 inches
The compact size allows installation in tight mounting boxes, including EU-type, 86-type, and 120-type boxes. You do not need to replace your wall box for a bulkier device. This makes it suitable for older homes with small electrical boxes. Compare this with larger smart switches that require deep boxes. The small form factor ensures a clean look without protruding from the wall plate.
Design and build details
According to the listing, the SONOFF ZBMINIR2 measures 1.68 inches by 0.79 inches. This compact footprint allows it to fit into standard EU-type, 86-type, or 120-type mounting boxes. The small size means you can install it in tight electrical spaces without needing a larger enclosure. The device comes in white, which helps it blend into most interior wall setups. It weighs nothing extra because it lacks a bulky plastic shell or external power adapter. You simply place the relay inside the wall box. The unit is a Zigbee end-device, meaning it connects directly to a hub rather than acting as a router itself. This design keeps the internal components minimal. The layout supports two-way control for staircase lighting. You can pair it with external rocker or push-button switches for manual operation. No neutral wire is required for basic installation, though the key specs note a neutral line requirement for full smart functionality. This flexibility lets you use it in older homes without rewiring. The finish is smooth and plain, matching standard switch plates. You get a clean look without exposed wires or large modules. The small dimensions also mean less heat buildup during operation. This is a practical choice for renters or homeowners who want discreet automation. The white color ensures it does not stand out visually. You install it once and forget about its physical presence. The design prioritizes function over form, keeping the focus on reliable smart control. This approach suits users who value hidden technology in their living spaces.
Setup and everyday use
You need a Zigbee hub to use this switch. The listing states it is a Zigbee end-device that requires a hub for connection. It does not connect directly to your Wi-Fi router. Once paired, the switch joins your local Zigbee mesh network. This setup allows you to control lights via voice commands using Amazon Alexa or Google Home. The device supports two-way control, which is useful for staircase lighting. You can install external switches like rockers or push buttons to manage the connected load manually. The listing notes that no neutral wire is required for easy installation. It works with loads as low as 3 watts without needing an anti-flicker module. This means you can use it with energy-efficient LEDs without issues. Daily use involves scheduling or countdown timers. You can set loops to automate your home environment. The local network ensures the switch works even if your internet connection fails. You retain control of your appliances through the Zigbee LAN. The compact size means it hides inside standard mounting boxes. This keeps your wall plates looking clean. The white finish blends into most decor. You set up scenes to trigger multiple devices at once. This simplifies your routine. The hub manages the communication, so you do not need to worry about signal strength from your phone. The switch responds to commands from the hub reliably. You get consistent performance for your smart lighting needs.
Before you buy this switch
This compact switch works best in homes that already use a Zigbee hub. You must verify your hub supports Zigbee 3.0 devices. The listing notes it is a Zigbee end-device, meaning it connects through the hub rather than directly to Wi-Fi. Check if your current smart home ecosystem, like Alexa or Google Home, integrates smoothly with your existing hub setup. Since it requires a neutral line, inspect your wall box before purchasing. Ensure there is a neutral wire available for safe installation. This device fits alongside other smart controls in your home by adding reliable local automation. It supports two-way control and voice commands. Consider if you need external switches for staircase lighting or scheduled timers. The small size allows it to blend into tight spaces without disrupting your home’s aesthetic. It is a practical choice for upgrading existing lighting circuits without replacing entire switch plates. Verify your electrical setup matches these requirements to avoid installation issues.
Check before you buy
- Confirm your hub supports Zigbee 3.0 protocols
- Check for a neutral wire in the wall box
- Verify Alexa or Google Home integration with your hub
- Ensure the mounting box fits the compact dimensions
