Xiaomi’s smart home ecosystem has reached such a level that choosing a central control device is no longer a trivial task. Whereas in the past, it was enough for a user to buy a simple gateway for motion sensors, today the market offers complex multimodular systems that combine dozens of communication protocols. The question of which hub to choose Xiaomi 3 versions becomes critical, as it depends on the stability of all your automation and compatibility with future devices.
The main confusion arises from the fact that users often understand the “third version” as different models: the classic Gateway 3 (CN/Global) and the more powerful Gateway 3 Pro. Both devices look similar, but have cardinal differences in hardware stuffing, supported protocols and, most importantly, in the ability to work without the Internet. In this article, we will analyze the technical nuances in detail so that you can make an informed decision.
Don’t underestimate the role of the gateway in building a reliable network, which takes over scripting, storing schedules, and bridges between your gadgets and Xiaomi servers or local management system. A mistake in the purchase phase can lead to the fact that after a year you find the incompatibility of new light bulbs or the inability to integrate with Apple HomeKit.
The evolution of Xiaomi gateways: from Zigbee to multimodule
Xiaomi’s smart home story is a journey from closed systems to open standards. Early generations of gateways worked exclusively with the Zigbee protocol, requiring a mandatory cloud connection to manage from the phone. This created delays and rendered the system useless when the Internet was shut down. The third generation of devices marks the transition to hybrid architectures.
Modern hubs like the Mijia Smart Multimode Gateway have learned to understand not only Zigbee but also Bluetooth Mesh, enabling devices that used to require separate bridges, such as thermometers or new-style smart switches, and even local control, which has revolutionized privacy enthusiasts.
It's important to understand that the term "version 3" is not the official name of the model, but rather the generation in the Mijia line, which is why you can find devices with similar designs but different functionality on store shelves, and the key factor in evolution has been the need to unify disparate devices into a single network without buying a dozen different bridges.
- 📡 Communication protocols: Modern hubs support up to three wireless standards at a time (Zigbee 3.0, Bluetooth Mesh, Wi-Fi).
- 🏠 Local Work: Ability to execute scenarios without access to the WAN, which increases system fault tolerance.
- 🔌 Power: Switching to more powerful power supplies to ensure stable operation of radio modules and built-in speaker.
Why is Zigbee 3.0 important?
Comparative analysis: Gateway 3 vs. Gateway 3 Pro
The most heated discussion is between two main contenders: the standard Mijia Smart Multimode Gateway (often referred to as simply Gateway 3) and its advanced version of the Mijia Smart Multimode Gateway Pro. Visually, they may differ by the presence of a built-in speaker in the Pro version or the shape of the case, but the main differences are hidden inside.
The regular third version does a great job of basic tasks: it combines sensors, switches and relays. However, its ability to integrate with external systems is limited. At the same time, the Gateway 3 Pro has built-in support for Apple HomeKit, which is a killer feature for owners of Apple equipment, which allows you to add Xiaomi devices directly to the Home app on the iPhone without using complex crutches like Homebridge.
Also worth noting is the difference in the number of connected devices. If the standard version is enough for a small apartment, then for a smart cottage, where the bill goes to hundreds of sensors, the Pro version will work more sturdily thanks to a more powerful processor and an improved antenna module.
When choosing between these models, you should also consider the presence of an integrated IR transmitter in some versions, which turns the hub into a universal remote. However, most often this feature is brought to a separate device, and the hub acts only as a coordinator. For most users, it is the presence of HomeKit and the price that becomes the decisive factor.
Technical specifications and supported protocols
To determine which hub to choose Xiaomi 3 version, you need to delve into the technical specifications. Both devices are based on chipsets that support the Zigbee 3.0 standard, which guarantees backward compatibility with older sensors.
Pro versions often use a more powerful radio module that provides better penetration through concrete walls, which is critical in apartment buildings where the air is jammed with signals from neighbouring routers and microwave ovens, and the stability of the connection is paramount here.
Below is a table comparing key parameters of popular third-generation gateway models. Note the local protocol-enabled column, as this determines the integration with Home Assistant or other local servers.
| Characteristics | Gateway 3 (CN/Global) | Gateway 3 Pro | Old Gateway 2 |
|---|---|---|---|
| Protocols | Zigbee 3.0, BT Mesh | Zigbee 3.0, BT Mesh, Wi-Fi | Zigbee 1.2 |
| Apple HomeKit | No (only through crutches) | Yes (indirectly) | No. |
| Local control | Limited. | Full support | Just a cloud. |
| Dynamician | Basic | Improved (Hi-Fi) | Basic |
Unlike the early generations, which required Ethernet connectivity (or no port at all), modern 3rd hubs often only have Wi-Fi connectivity to communicate with the router, making installation easier but can affect stability when a signal is poor.
💡
If you plan to use a hub in a poor Wi-Fi area, consider buying a model with an Ethernet port or using a Wi-Fi repeater. The stability of the Zigbee network depends on the quality of the gateway itself’s connection to the router.
Integration with ecosystems: HomeKit, Google Home and Yandex
The Xiaomi Mi Home ecosystem is great friends with Yandex Alice and Google Assistant, but native support for Apple HomeKit is not available on all models. If you own an iPhone, iPad or Apple Watch, the lack of native support for HomeKit can be a serious inconvenience.
For Android users and Google fans, the situation is simpler: almost any Xiaomi 3 hub is easily linked to Google Home through official integration, allowing you to control light and voice sensors. With Yandex, the situation is similar, but requires setting up through your Mi Home account and the skill of "Xiaomi Home" in the Yandex app.
The HomeKit situation needs more detailed consideration, and only models labeled "Works with Apple HomeKit" on the box can be added to the Home app with a simple scan. QR-For other models, enthusiasts use software solutions such as Xiaomi Gateway 3 integration for Home Assistant, but this requires a separate server and technical knowledge.
- 🍏 Apple HomeKit: Requires Apple Security Chip and Certification (available in Pro versions).
- 🔊 Google Assistant: Supported by most models via cloud synchronization.
- 🗣 Yandex Alice: Full support for voice control and scripts through the Mi Home skill.
⚠️ Warning: When buying a hub for use with HomeKit, be sure to check for the "Works with Apple HomeKit" logo on the package (CN) Without global certification, HomeKit may not work even after changing the region in the application.
Local management and work without the Internet
One of the biggest advantages of the third generation of hubs is that it can be local, and in the early versions, when you shut down the Internet, the smart home becomes a bunch of plastic. Scripts don't work, sensors don't send notifications. The version 3 hub changes that paradigm, allowing you to store the logic of automation on the device itself.
To implement full local management often requires the use of third-party software, such as the Home Assistant platform, which in conjunction with this, the Xiaomi hub turns into a powerful controller that does not send data to the cloud in China, which increases the speed of the system’s response and ensures data privacy.
Even without third-party software, the new hubs can perform basic scenarios (e.g., “if the motion sensor is triggered, turn on the lights”) autonomously, but the control from the smartphone from the outside (via 4G) in this case will not work, since remote access still requires an Internet connection.
☑️ Checking before buying for local work
It’s important to note that local management is evolving, with Xiaomi gradually opening up APIs to developers, allowing for more complex chains of action that don’t depend on your Internet channel speed, especially for security systems where every millisecond matters.
Practical recommendations for installation and configuration
Once you’ve decided which hub to choose Xiaomi 3, it’s important to install it correctly.The device’s location plays a key role in the stability of the Zigbee network. Since the hub is the coordinator, it should be in the geometric center of your smart home system, preferably on a hill.
It's not recommended to hide the hub in closed metal panels or behind TVs. Metal shields the signal, and running electronics creates interference. The ideal place is an open shelf in the central room or corridor, where the signal will spread evenly in all directions.
When you first set up, make sure your smartphone is connected to a 2.4GHz Wi-Fi network. Xiaomi hubs don't support 5GHz networks for the primary configuration. If you have a combined network on the router, try splitting them temporarily or moving away from the router so that the phone switches to 2.4GHz.
⚠️ Warning: Do not place a hub near powerful sources of radio interference, such as microwave ovens, baby monitors or powerful Wi-Fi routers from other manufacturers.This can lead to periodic communication breaks with sensors.
To expand coverage, use network-powered devices (plug relays, smart light bulbs) that act as repeaters on a Zigbee network, amplifying the signal for battery sensors in distant rooms.
💡
The correct location of the hub in the center of the apartment and the presence of at least 2-3 relay outlets increase the stability of the Zigbee network by 40-50%.
