Xiaomi gateways for a smart home: which to choose and what to pay attention to

The central element of any smart home ecosystem is the gateway (or hub) that connects all devices to each other and to the cloud. Without it, most of Xiaomi’s sensors and actuators simply won’t work: neither the light bulbs will turn on on schedule, nor the cameras will record video when you move. But how to choose the right gateway among a dozen models from Xiaomi, Aqara and Redmi? The answer depends on your tasks, budget and scale of the system.

In this article, we will analyze all the current Xiaomi gateways (including models under the Aqara and Redmi brands), compare them by key parameters: supported protocols (Zigbee 3.0, Zigbee). E1, Thread, maximum number of connected devices, speaker, compatibility with Home Assistant and other systems, and also tell us what hidden limitations each hub has – for example, why Xiaomi Mi Smart Home Gateway 3 is not suitable for large homes, and Aqara Hub M2 It may be in conflict with some Xiaomi sensors.

Spoiler: If you need the most universal gateway for 20+ Thread-enabled devices with no cloud on-premises management, look at Aqara Hub E1. And for minimalist c. 5-10 The Redmi Smart Gateway will also be enough for sensors, but with reservations, which you can read below.

1.Why do you need a gateway in Xiaomi's smart home?

Many newcomers mistakenly think that Xiaomi smart light bulbs or sockets can work directly over Wi-Fi or Bluetooth. In practice, most of the ecosystem's devices (especially motion sensors, door openings, buttons) use the Zigbee protocol, a low-energy communication standard optimized for IoT. And here's the problem: a smartphone or router can't "talk" on Zigbee. That's what a gateway is for, it performs three key functions:

1. Bridge between protocols: converts signals Zigbee/Thread commands for the Mi Home cloud or local area network.

Automation Center: Processes triggers (e.g., “if motion sensor is triggered, turn on the light”) without cloud involvement (in some models).

3. backup channel: if the Internet is down, the locally controlled gateway will continue to operate under the specified scenarios.

⚠️ Warning: Without a gateway, you can only connect Wi-Fi devices to the Mi Home (such as Yeelight light bulbs or Xiaomi Mi Home Security Cameras). Sensors, switches and most actuators simply won’t be defined in the app.

2. Key parameters in the selection of a gateway

Before we compare models, we'll figure out what to look for when buying, and a mistake in choosing can cause the system to brake, the devices to fall off, and some scenarios to fail at all.

Supported protocols:

• 🔄 Zigbee 3.0 is the basic protocol for most Xiaomi and Aqara devices. E1 (Aqara Hub E1) compatible with Thread and has better protection against interference.
• 🧵 Thread is a new smart home standard (used in Apple HomeKit and Google Home) and is currently only supported in the Aqara Hub. E1 and M2.
• 📶 Wi-Fi is used to connect the gateway to the cloud. All modern models support dual-band (2.4/5 GHz, but some (such as Mi Gateway) 3) work only 2.4 GHz.

Maximum number of devices:

Manufacturers specify “up to 128 devices”, but in practice the real limit depends on the type of devices and the load on the network.

• 🏠 Up to 10 devices – any gateway, even a budget Redmi Smart Gateway.
• 🏢 10-30 Xiaomi Mi Smart Home Gateway 3 or Aqara Hub. M1S.
• 🏭 30+ Devices: Aqara Hub only E1 or M2 (Thread-enabled for load sharing).

Local control:

Xiaomi Mi Smart Home Gateway 3 and Redmi Smart Gateway DO NOT support local management without the cloud.This means that if Xiaomi servers crash or your Internet goes down, automation will stop working. E1 and M2 Some of the scripts are executed locally.

Additional functions:

• 🔊 Built-in speaker for alarms or voice alerts (available in all models except Redmi Smart Gateway).
• 💡 Illumination — RGB-Status indicator (useful for visual monitoring).
• 🔌 Ethernet port for stable connection (only available in Aqara Hub) E1).

💡

If you’re planning to integrate a smart home with Home Assistant or Apple HomeKit, opt for Aqara gateways – they’re better supported by third-party systems than the original Xiaomi.

3.Comparison of all Xiaomi gateways in 2026

The table below shows the current models of gateways that can be bought in official stores (including Aqara and Redmi, as they are fully compatible with the Mi Home ecosystem).

⚠️ Note: Xiaomi and Aqara gateways are not compatible at the automation level. For example, if you connect Xiaomi sensor to the Aqara hub, it will appear in the application, but some scenarios may not work.

4. Which gateway to choose: detailed recommendations

The choice of gateway depends on your tasks, and below are specific recommendations for different scenarios.

🏡 For a studio apartment or a small house (up to 10 devices)

If you need to connect the lights, 2-3 sensor and socket, the most budget option is enough:

• 💰 Redmi Smart Gateway is the cheapest (2 200 ₽), but with limitation in 32 The device (actually stable) 10-15). Cons: no speaker, only Wi-Fi 2.4 GHz, no local management.
• 🏆 Xiaomi Mi Smart Home Gateway 3 is a little more expensive (3500) ₽), But there's a speaker for alarms and RGB-It's good if you want to use the airlock as a night light or an alarm clock.

Both options are not suitable if you plan to expand the system to 20.+ Devices or Integration with Home Assistant.

🏢 For the home or office (10-30 device)

We need a more powerful hub here:

• ⚡ Aqara Hub M1S — Optimal balance of price (4 500) ₽) It supports up to 30 devices stable, there's a speaker for alerts.
• 🌐 Aqara Hub M2 — If you need Thread for future devices (like Apple's HomeKit sensors) it's 5,800. ₽.

⚠️ Note: If you already have Xiaomi devices (e.g. Mi sensors) Door/Window Sensor, check their compatibility with Aqara on the official list.Some older models may not work properly with Aqara hubs.

🏭 For large systems (30)+ Devices and Integration with Home Assistant

The only option is the Aqara Hub. E1 (6 200 ₽). Why?

• 🔗 Thread support + Zigbee E1 — The load can be distributed between protocols.
• 🖥️ Ethernet Port is More Stable Than Wi-Fi.
• 🏠 Local management – part of the scenarios works without the cloud.
• 🍎 HomeKit and Home Assistant Compatibility – Easily Integrated into Other Systems.

💡 If you already have a Xiaomi Mi Gateway 3 gateway and want to expand the system, don’t rush to buy a second hub. Try breaking the devices into groups by floor/room and connecting them to different Zigbee channels (if the gateway supports multiple networks).

Make sure all your devices support the gateway protocol (Zigbee) 3.0/Thread)

Check compatibility with Mi Home or Aqara Home (some devices only work in one app)

Evaluate the need for local governance (if the Internet is unstable)

See if there is an Ethernet port (if Wi-Fi is weak)

Verify the maximum number of devices with your expansion plans-->

5. Frequent problems and how to avoid them

Even a well-chosen gateway can be unstable, and here are the common mistakes and their solutions:

1.The devices are permanently switched off

Reasons:

• 📡 Zigbee weak signal: Gateway should be in the center of the house, not in the corner.
• 🔋 Discharged batteries in sensors (especially in Mi) Door/Window Sensor).
• 🚫 Channel overload – if 30 are connected to one gateway+ Devices, break them into two hubs.

2. Automation doesn't work

What to check:

• ☁️ Mi Home Cloud – If the Internet is disabled, scripts on gateways without local management do not work.
• ⚙️ Trigger settings – sometimes the condition only works when the state changes (e.g., “if the motion sensor has changed state to ‘detected'").
• 🔄 Firmware conflict – update the gateway and device software to the latest version.

3.The gateway does not connect to Wi-Fi

Decision:

• 📶 Check that the router is operating in mode. b/g/n (not).
• 🔒 Turn off the filtering. MAC-address.
• 🔄 Reboot the gateway (turn off power for 30 seconds).

💡 Useful advice: If you have multiple gateways Xiaomi/Aqara In one network, assign them static IP-This will prevent conflicts when you reconnect.
