Aqara vs Xiaomi: What’s the Real Difference and What to Choose for a Smart Home?

If you're planning to build a Xiaomi-based smart home, you'll eventually come across the Aqara brand. Both of them offer sensors, switches, cameras and other gadgets, but the way they're designed is fundamentally different. Some people praise Aqara for its reliability and advanced settings, others choose Xiaomi for its simplicity and accessibility. So where's the truth?

At first glance, the difference between the devices is minimal: both brands use the Zigbee protocol, integrate into the Mi Home app (now Xiaomi Home) and support voice assistants. However, deep analysis reveals that Aqara is a separate ecosystem with its own hubs, firmware and logic, while Xiaomi is betting on mass and unification. In this article, we will discuss 7 key differences that will help to avoid mistakes when buying and build a smart home without “crutches”.

1.Who manufactures devices: the history of brands

Aqara is a subsidiary of Lumi United Technology, which originally developed smart devices exclusively for Xiaomi under the MiJia brand. However, in 2016, Aqara became an independent brand, retaining close integration with the Xiaomi ecosystem. Today it is a separate player in the market with its own hubs (Aqara Hub M2, Camera Hub G3) and the Aqara Home branded app.

Xiaomi, in turn, continues to produce smart home devices under the brands MiJia, Xiaomi Smart Home and Yeelight (for lighting), the main difference is the centralization of management: all Xiaomi gadgets are originally sharpened to work through the Xiaomi Home app and often require the presence of a Mi/Xiaomi Gateway (gateway).

• 🏭 Aqara: an independent brand with its own hubs and firmware, but compatible with Xiaomi.
• 🤝 Xiaomi: One ecosystem where all devices are managed via Xiaomi Home.
• 🔄 Common: Both brands use Zigbee 3.0 protocol and can work together (with reservations).

2. Device compatibility: Can Aqara and Xiaomi be mixed?

Aqara and Xiaomi devices are technically compatible, but only if two conditions are met: the presence of a hub (gateway) and the correct firmware. For example, the Aqara Motion Sensor motion sensor can be connected to the Xiaomi Gateway 3, but this will require:

1. Update the lock firmware to the latest version.
2. Use the Xiaomi Home app (Aqara Home will not show Xiaomi devices).
3. Add devices manually through the “Other” mode (Add Device → Zigbee → Other).

The reverse is more complicated: Xiaomi sensors (such as Mi Door/Window Sensor 2) may not work consistently with the Aqara Hub M2 hub due to differences in implementation of the Zigbee protocol. Problems manifest in reaction delays, spontaneous shutdowns or the lack of certain functions (for example, adjusting the sensitivity of the sensor).

💡

Before buying, check the list of compatible devices on Aqara’s official website in the Compatibility List section. Not all Xiaomi models are supported by Aqara hubs, even if they use Zigbee.

⚠️ Note: If you use the Aqara Hub and Xiaomi Gateway on the same network, place them at least 3 meters apart. Otherwise, Zigbee networks may conflict, leading to loss of connection with sensors.

3. Communication protocols: Zigbee vs Wi-Fi vs Thread

One of the main differences between the brands is the communication protocols used. Xiaomi has traditionally favored Wi-Fi for simple devices (outlets, lamps) and Zigbee for sensors and switches. Aqara is betting on Zigbee 3.0 as the main protocol, but also experimenting with Thread (for example, in the Aqara FP2 Presence Sensor).

Let’s look at the pros and cons of each approach:

• 📶 Wi-Fi (Xiaomi):
• 🐝 Zigbee (Aqara/Xiaomi):
• 🧵 Thread (Aqara):

The key takeaway is that if you want a scalable system with dozens of sensors, Aqara on Zigbee will be more reliable. For a small apartment with 3-5 devices, Xiaomi will also do on Wi-Fi, but be prepared for possible lags when the network is overloaded.

💡

For maximum stability, avoid mixing Zigbee networks from different brands. If you use both the Aqara Hub and Xiaomi Gateway, set them up on different channels (e.g. 11 and 20).

4.Software: Mi Home vs Aqara Home

Both brands have their own app for managing devices, but their capabilities are very different. Xiaomi Home (formerly Mi Home) is focused on the mass user: a simple interface, basic automation and minimal settings. Aqara Home, by contrast, offers advanced functionality for smart home enthusiasts.

Let's compare the key features:

The main advantage of Aqara Home is local automation, which means that scenarios (for example, “if the motion sensor is triggered, turn on the lights”) will work even without the Internet. At Xiaomi Home, most automation is cloud-dependent, leading to delays of up to 1-2 seconds.

5. Prices and availability: which is more profitable?

Xiaomi device price is traditionally cheaper than Aqara 20–30%. For example, the door opening sensor Xiaomi Mi Door/Window Sensor 2 near 600–800 Aqara Door and Window Sensor will be available for the 1 200–1 500 The difference in price is justified:

• 🔋 Autonomy: Aqara sensors last from batteries up to 5 years, while Xiaomi has 1-2 years.
• 📊 Accuracy: Aqara uses more sensitive sensors (e.g. temperature sensors, error). ±0.3°C against C. ±1°C's Xiaomi).
• 🔄 Reliability: Aqara less likely to lose connection to the hub thanks to optimized Zigbee stack.

On the other hand, Xiaomi is more likely to hold sales and promotions, and devices are easier to find in offline stores. Aqara has to order through official distributors or marketplace (for example, AliExpress, Beru), which increases the delivery time.

⚠️ Note: When buying Aqara devices on AliExpress, check the firmware region. Some models (e.g. Aqara Hub) M2) come with Chinese firmware that does not support Russian and has restrictions on integrations.

Make sure your hub supports the device | Check the firmware version (should be international) | Pay attention to the frequency of Zigbee (2.4 GHz for Russia) | Compare prices at official dealers and on marketplaces-->

6.Integration with other ecosystems: HomeKit, Google Home, Yandex

If you’re not just using a smart home in the Xiaomi ecosystem, it’s important to consider compatibility with other platforms.

• 🍎 Apple HomeKit:
• 🤖 Google Home / Assistant:
• 🗣️ Yandex Alice:

For iPhone owners or Google Nest users, the choice is obvious — Aqara offers much more features, but with Yandex, both ecosystems work roughly the same way, except for Zigbee sensors, which are often not visible in Xiaomi Smart Home.

7. Which devices are better to choose: recommendations by category

To avoid confusion in the range, here are specific recommendations for categories of devices:

If you want maximum reliability and are willing to take the time to set up, choose Aqara. Xiaomi is the best option for a quick start with minimal investment. The best option is to combine both brands using Aqara for critical sensors (security, climate) and Xiaomi for secondary devices (outlets, lamps).
