What Xiaomi Gateway to Choose in 2021: A Complete Guide to Models and Their Features

Creating a smart home based on the Xiaomi ecosystem begins with the choice of a central element – a gateway (hub), which connects all devices into a single network. In 2021, the range of hubs from Xiaomi and its sub-brand Aqara has expanded significantly, but not all models are equally useful for Russian users. The main problem is the lack of official support for many devices in our region, which leads to difficulties with firmware, voice assistants and integration with Apple HomeKit or Google Assistant.

In this guide, we will look at all the current models of Xiaomi gateways 2021 release, their specifications, compatibility with devices and nuances that are important to consider before buying.

Why is Xiaomi’s gateway a must-have element of a smart home?

Many newcomers mistakenly believe that smart light bulbs, sensors and outlets can work on their own via Wi-Fi or Bluetooth, which in practice leads to delays in management, quick battery discharge and inability to create complex scenarios.

• 🔄 Centralized management: All devices connect to a single hub rather than a router, reducing network load.
• ⚡ Instant response: commands are executed locally (without the cloud), which is critical for motion sensors or alarms.
• 🛠️ Automation: Create scenarios like “if the door opener is triggered, turn on the lights and send a notification».
• 🔒 Zigbee network is less vulnerable to hacker attacks than Wi-Fi.

Without a gateway, you lose half of the functions of a smart home. For example, the Xiaomi Aqara water leak sensor without a hub will only be able to beep when it is triggered, but it will not turn off water through a smart tap or send a push notification to the phone.

⚠️ Note: Xiaomi gateways are not compatible with other Zigbee brands (e.g. Philips Hue or other devices). IKEA Tradfri.The exception is Aqara Hub. M2, which supports some third-party protocols through plugins.

Xiaomi Gateway Compatibility with Devices: What Works and What Doesn’t?

One of the main questions when choosing a gateway is what devices it supports. There is a nuance in the Xiaomi ecosystem: not all sensors and actuators are compatible with all hubs. Below are the current information for 2021.

Devices compatible with ALL gateways Xiaomi/Aqara:

• 💡 Smart lamps: Yeelight, Mi LED, Aqara Bulb.
• 🔌 The Mi Smart Plug, Aqara Wall Outlet.
• 🚪 Opening sensors: Mi Door/Window Sensor, Aqara Door Sensor.
• 🌡️ Temperature/humidity sensors: Mi Temperature Sensor, Aqara TH Sensor.
• 🚨 The Mi Wireless Switch and the Aqara Mini Switch.

Devices with limited compatibility:

• 💦 Aqara Water Leak Sensor does not work with Mi Gateway 2.

Before buying a device, be sure to check its compatibility with the selected gateway on the official website or in the Mi Home app. For example, the Mi Vibration Sensor vibration sensor will not work with the Mi Gateway 2, although this is not always indicated in the product description.

Which Xiaomi gateway to choose for specific tasks?

The choice of hub depends on what smart home scenarios you plan to implement, and below are recommendations for typical tasks.

🏠 Basic smart home (lights, sockets, sensors)

Xiaomi Mi Gateway 3 supports all major devices and allows you to create simple automations such as:

• “If the motion sensor is working, turn on the lights.”
• «If the temperature is below 18°C, turn on the heater».
• If the door is open for more than 5 minutes, send a notification.

🍎 Integration with Apple HomeKit

Just the Aqara Hub. M2 Or Aqara Camera Hub. G3. They are Apple certified and support HomeKit Secure Router, which is important for security.

📡 Stable operation without cloud (local scenarios)

Aqara Hub M2 It allows you to create scenarios that work even without the Internet (for example, alarms when the sensor is triggered).

🎮 Management of household appliances by IR

Just the Aqara Hub. M2 — It has a built-in IR-blaster, which can replace the remotes from the air conditioner, TV or fan.

👁️ Video surveillance + smarthouse

Check compatibility with your devices

Determine if you need HomeKit (for iPhone)

Decide if working without the internet is important (Ethernet vs Wi-Fi)

Assess the need IR-blaster

Consider the budget (Aqara Hub) M2 more expensive but more functional

Setup of the gateway Xiaomi: step-by-step instructions for Russia

The process of setting up the gateway depends on the model, but the general steps are the same. Consider a universal instruction based on the Russian region (where server problems often occur).

1. Connecting the gateway to power and network

All Xiaomi hubs connect to the outlet 220V. Next:

• For the Mi Gateway 3 and Aqara Camera Hub G3: Connect to Wi-Fi via the app.
• For Aqara Hub M2: It is better to use Ethernet (a cable from the set).

2. Selection of region in the annex

This is a critical moment! By default, the gateways are set to China, which leads to:

• Delays in management (data is sent to Chinese servers)
• Inability to connect voice assistants (Alice, Google)
• Problems with firmware updates.

To change the region:

1. In the Mi Home app, go to profile (top right corner).
2. Click on a country (e.g., “China”) and select “Russia” or “Europe.”
3. Remove the gateway from the application and add it again.

💡

If the gateway stops connecting after the region change, reset it to the factory settings. To do this, hold the button on the case for 10 seconds until the yellow LED flashes.

3. Addition of devices

Algorithm for all gateways:

1. In the app, click "Add device» (+ top-right).
2. Select a category (e.g., “Sensors”).
3. Click on the device you want and follow the instructions (usually you need to press the button on the sensor).

If the device is not located:

• Check if your gateway supports it (see table above).
• Bring the device closer to the hub (maximum 1-2 meters for connection time).
• Make sure the battery is not dead (newer sensors often have a protective film inserted).

4. Automation setting

Example of creating a scenario "Switch on the light when moving":

1. Go to the section "Automation» → «Add».
2. Select the condition: "Motion sensor» → «Traffic detected».
3. Select the action: "Smart lamp» → «Turn on».
4. Save the script.

⚠️ Note: In the Russian region, some scenarios may not be saved due to server limitations, in which case use Home Assistant or Node-RED for local automation.

Frequent problems and their solutions

Even after you set up the gateways properly, Xiaomi can be unstable, and let's look at the common mistakes and how to fix them.

🔴 Gateway does not connect to Wi-Fi

Causes and solutions:

• 📶 Weak Wi-Fi signal – bring the gateway closer to the router or use Ethernet (for Aqara Hub) M2).
• 🔒 Incorrect password – enter it again (registration is important!).
• 🌐 Lockdown MAC-Addresses – check router settings (open access to the device).
• 🔄 Outdated firmware – update the gateway through the Mi Home app.

🟡 Devices are periodically switched off

A common problem with Zigbee networks.

• 📡 Wi-Fi interference – change the Wi-Fi channel on the router (better use 1, 6 or 11).
• 🔋 Weak signal – add a Zigbee repeater (like Aqara smart socket).
• 🔄 Network congestion – do not connect more than 30 devices to one gateway.
• ⚡ Power problems – try another power supply (sometimes replacing it helps) 5V/2A).

🟢 Scripts don't work.

Check it out.

• 🌍 Region in app – some automation blocked in China region.
• 🔗 Scenario conditions – for example, a motion sensor may not work due to low sensitivity.
• 📱 Application updates – in older versions of Mi Home there are bugs.
• 🔄 Local scripts – if you use Home Assistant, check logs for errors.
