Xiaomi Smart Home or Tuya: Which is Best for Automation in 2026?

Choosing a smart home platform isn’t just about buying a few gadgets, it’s about investing in an ecosystem that will drive your home for years to come. Xiaomi and Tuya are now leading the market for budget and mid-price solutions, but their approaches are radically different. One offers a closed but streamlined ecosystem with its own protocols and brand design, and the other an open platform with support for thousands of devices from different brands.

The big question is, what's more important, stability and uniform style (like Xiaomi) or flexibility and freedom of choice (like Tuya)? In this article, we'll break down the technicalities, compare prices, analyze compatibility with other systems (including Home Assistant and Google Home), and uncover the pitfalls that manufacturers keep silent about. Without embellishment and marketing slogans, only facts that are proven in practice.

Spoiler: If you dream of being completely automated with hundreds of scenarios, the answer is not as obvious as it sounds, and if you just need a couple of light bulbs and sockets, you definitely shouldn't overpay for the brand. Let's get this straight.

System architecture: closed ecosystem vs open platform

Xiaomi’s main difference from Tuya lies in their philosophy: Xiaomi builds a vertically integrated ecosystem where all devices work through its own hub (Mi Home Gateway or Aqara Hub) and the Zigbee 3.0 protocol. This guarantees minimal latency and high reliability, but limits you to only Xiaomi devices, Aqara devices or certified partners.

Tuya, by contrast, is an open cloud platform used by hundreds of brands (from NooLite to BlitzWolf) that connect to Wi-Fi, Zigbee or other devices. BLE, It's managed through the Tuya Smart cloud, and the advantage is that there's a huge selection of low-cost devices, and the disadvantage is that it relies on the stability of Tuya servers and the potential for delays in management.

Critical: If Xiaomi has all the data (except cloud backups) stored locally on the hub, Tuya defaults to sending all telemetry to the cloud, which means that when you shut down the Internet:

• 🔄 Xiaomi devices will continue to work on the local network (if the scripts on the hub are configured).
• ⚠️ Most Tuya devices will be unavailable for management (except for those that support the device). LAN Mode).

Security important: In 2023, researchers discovered vulnerabilities in the Tuya protocol that allowed remote control of devices without authorization, which Xiaomi did not have, but its system is closed for audit.

2. Compatibility with other platforms: who is friends with Home Assistant and Google Home

If you plan to integrate a smart home with other systems (like Home Assistant, Google Home, or Apple HomeKit), the choice between Xiaomi and Tuya becomes even more difficult.

Key takeaway: If you want maximum compatibility with Home Assistant, Xiaomi is preferable – its devices are easier to connect locally without the cloud. For Google Home, there is almost no difference, and for HomeKit, both options are bad (you will have to use workarounds).

⚠️ Note: When you integrate Tuya with Home Assistant through the cloud, you depend on the stability of Tuya servers in China. In 2023, there were cases when users in Europe lost control of devices for several hours due to blocking.

3. Device range: what can be automated

Here, Tuya is the undisputed leader in the number of devices supported, and the platform is used by more than 10,000 brands, so you'll find:

• 💡 Lighting: light bulbs, LED tapes, panels, chandeliers (including RGB and tunable white).
• 🔌 Power management: sockets, relays, switches (including for hidden wiring).
• 🌡️ Climate: thermostats, heaters, air conditioners, humidifiers, fans.
• 🚪 Security: sensors for opening, movement, leakage, smoke, cameras (including PTZ and with IR illumination).
• 🔄 Other: motorized curtains, robot vacuum cleaners, smart locks, irrigation systems.

Xiaomi offers a more modest but carefully crafted range:

• 💡 Light bulbs (Yeelight, Mi) LED), light-belt.
• 🔌 Powered by Mi Smart Plug, Aqara Wall Switch).
• 🌡️ Sensors (Aqara: temperature, humidity, opening, movement, leakage).
• 🚪 Home Security Camera (Aqara Camera Hub).
• 🔄 Smart locks (Mi Smart Door Lock), robot vacuum cleaners (Mi Robot Vacuum).

The main difference: Xiaomi all devices undergo strict quality control and have a single design, while Tuya quality depends on the manufacturer – you can run into cheap Chinese consumer goods with poor build.

4.Prices: What is cheaper in the long run

At first glance, the Tuya seems cheaper: for example, a smart outlet on its platform costs from 500-800 rubles, while a similar Mi Smart Plug will cost 1,200-1,500 rubles.

Cost of ownership Xiaomi:

• ✅ Hub (Mi Home Gateway or Aqara Hub) – 2,500-4000 rubles (buyed once).
• ✅ Devices are more expensive by 30-50%, but last longer (guarantee 2-3 years vs 1 year for non-Naym brands on Tuya).
• ✅ No subscription fee.

Cost of ownership of Tuya:

• ✅ No mandatory hub (you can do with Wi-Fi devices).
• ⚠️ Cheap devices often break down after 1-2 years (especially sensors and relays).
• ⚠️ Some brands charge for cloud features (e.g. Ewelink 3)$ monthly for extended scripts).

Example of calculation for an apartment (10 devices):

But after 3 years, the picture may change: if the Tuya system fails 2-3 devices, their replacement will cost another 3000-5000 rubles, while Xiaomi devices will last longer.

💡

If you plan on the system for 20.+ Xiaomi will be more profitable in the long run due to reliability. For testing or a small apartment (5-10 devices), Tuya is cheaper at the start.

5. reliability and stability of work: who less often fails

Xiaomi is famous for its stability, but there are nuances:

• ✅ Local scripts on the hub work even without the Internet.
• ✅ Delays in management – minimal (100-300 ms).
• ⚠️ Mi Home server problems occur every 2-3 months (usually 10–30 minutes).
• ⚠️ Some Aqara devices require a separate hub and are not compatible with the Mi Home Gateway.

Tuya is less predictable:

• ✅ Wi-Fi devices connect directly to the router (no dependence on the hub).
• ⚠️ Delays can be as long as 1-2 seconds (due to cloud processing).
• ⚠️ Tuya servers are sometimes blocked in some countries (for example, in 2022 there were problems in Europe).
• ⚠️ Cheap devices can “fly” from the network once every 1-2 weeks (requires a reconnection).

Test for fault tolerance (held in 2026):

• 🔋 Xiaomi: After a power outage for 12 hours, all devices automatically restored communication.
• 🔌 Tuya: 2 out of 10 devices required manual reconnection.

⚠️ Warning: If you have a volatile Internet (e.g., mobile as your primary channel), Tuya devices will constantly fall off.

Scenarios and Automation: Who is Flexible

Both platforms support scripting, but the approaches are different:

Xiaomi (Mi Home/Aqara):

• ✅ Simple visual script editor (such as "if... then…").
• ✅ Support for time, geolocation, weather, and other devices as triggers.
• ⚠️ Limit the number of scripts (up to 20 free versions).
• ⚠️ No JavaScript support or complex logic (e.g. loops).

Tuya:

• ✅ More triggers (including voice commands via Alice)/Google).
• ✅ Support for variables and conditional logic (in advanced mode).
• ⚠️ Scenarios work through the cloud – when the Internet breaks down, automation shuts down.
• ⚠️ The editor’s interface is overloaded (difficult to understand for a beginner).

An example of a complicated scenario that can only be done in Tuya:

1. Turn on the lights by 30% and send a notification to the phone.

Xiaomi does not implement such a scenario – you can set up one condition at most ("if you move, turn on the light").

7 Privacy and Security: Who Is Watching You

Both platforms collect data, but in different amounts:

Xiaomi:

• 📍 Gathers IP-address, device model, software version.
• 📍 Camera and microphone data (if any) are stored on servers in Singapore.
• ✅ You can turn off telemetry collection in settings (but this will limit the functionality).
• ✅ Local scenarios work without transferring data to the cloud.

Tuya:

• 📍 Collects all telemetry (including history of on/off, sensor data).
• 📍 The servers are located in China (probable problems with the servers). GDPR European users).
• ⚠️ There is no option to completely disable data collection.
• ⚠️ In 2023, there were incidents with the leak of user logs.

How to minimize the risks:

• 🔒 For Xiaomi: Use local scripts and turn off cloud sync in the hub settings.
• 🔒 For Tuya: Set up Home Assistant with local management (via Tuya Local or LocalTuya).

⚠️ WARNING: If you use smart locks or cameras, Tuya is not the best choice because of the risk of data leakage. Xiaomi is more reliable in this regard, but also not perfect (in 2020, there were scandals with the transfer of data from cameras to servers in China).

8 Support and updates: who does not abandon users

Xiaomi regularly releases updates for its devices, but:

• ✅ Hubs and key devices are supported for 3-5 years.
• ⚠️ Budget devices (e.g. first-generation Mi Smart Plug) will no longer be updated after 2 years.
• ⚠️ Updates sometimes break stability (for example, firmware for the Aqara Hub in 2023 caused problems with the connection of sensors).

Tuya updates firmware less often, but:

• ✅ Critical bugs are fixed quickly (e.g., vulnerabilities in the protocol).
• ⚠️ Many nounaime brands never update their devices.
• ⚠️ New features only appear for flagship devices (e.g. Matter support).

How to check the support of the device:

1. Check the date of the last update in the app.
2. Read reviews on AliExpress or forums (for example, 4PDA).
3. Check if the device supports local control (this is a sign of long-term support).
