How to combine all Xiaomi devices into a single ecosystem: from the phone to the smart home

Xiaomi’s ecosystem is not just a collection of individual gadgets, but a complex network of devices that can communicate with each other through cloud services and local protocols. However, many users face the problem: smartphones, smart lamps, robot vacuum cleaners or fitness bracelets work in isolation, do not synchronize with each other or require separate applications. In this article, we will discuss how to combine all Xiaomi devices under one account, configure them to work together and manage them from one screen — whether it is a smartphone, a tablet or even a voice assistant.

The main difficulty is that Xiaomi uses several platforms for different types of devices: Mi Home (for smart home), Mi Fit (for wearable gadgets), Mi Cloud (for synchronizing smartphone data). In addition, some devices only support local management via Mi Mesh or Zigbee, while others require a connection to Wi-Fi. We will analyze each scenario in detail, from basic account binding to configuring complex automations between gadgets.

1. Create and set up a primary Mi Account

The first step to connecting devices is to sign up for a single Mi Account, so without it, you can't sync data between gadgets, manage them remotely, or set up automation. Importantly, one account can be linked to an unlimited number of devices, but some features (like cloud photo storage) have limits on the amount of free users can use.

To create an account:

• 📱 Install the Mi Account app (for Android) or go to account.xiaomi.com.
• 🔑 Register by phone number or email. For users from Russia, it is recommended to specify the number with the code. +7 – This will make it easier to restore access.
• 🛡️ Enable two-factor authentication (2FA) This will protect your account from being hacked, especially if you plan to connect a smart home.

After registration, log in to this account on all Xiaomi devices:

• 📲 On a smartphone: Settings → Accounts and synchronization → Mi Account.
• ⌚ On a smart watch or bracelet: through the Mi Fit or Zepp Life app.
• 💡 On smart lamps or sockets: via Mi Home at the first connection.

⚠️ Note: If you have previously used different accounts for different devices, you will have to untie them and re-assign them, for example, a robot vacuum cleaner tied to an old account will not appear in a new one. Before resetting the anchor, make sure you have access to your previous account – otherwise the device may remain locked.

2 Connecting smartphones and tablets to the ecosystem

Xiaomi is the control center for all other gadgets, and in order for it to interact with other devices, you need to:

2. Activate Sync in Settings → Accounts and Sync → Mi Cloud. Enable Contacts, Notes, Photos and Devices options.
3. Install key applications: 🏠 Mi Home – to manage a smart home. 🏃 Mi Fit or Zepp Life for fitness bracelets and watches. 📺 Mi TV Remote – if you have a Mi TV TV.

• 🔄 Automatically sync notifications to a fitness bracelet (e.g., show incoming calls to Mi Band 7).
• 🔌 Manage smart outlets through a widget on the home screen.
• 📱 Use as a remote for TV or air conditioning (via the IR port, if it is in the model).

💡

If you have multiple Xiaomi smartphones (e.g., work and personal), you can sign in to the same Mi Account on both devices, allowing you to synchronize notifications, notes, and even call history between phones.

Zigbee-based devices (like Aqara sensors) will require a Mi Gateway. Connect it to a socket, add it to the Mi Home, and then tie the sensors through the gateway. Note: one gateway supports up to 32 devices, but larger homes may need multiple gateways.

5. Synchronization of data between devices

One of the key benefits of the Xiaomi ecosystem is that it automatically synchronizes data between gadgets.

3. For wearables: In the Mi Fit app, check the Data Sync section and enable the option of Cloud Backup.

Important: a free Mi Cloud account only provides 5GB of storage. If you sync photos and videos in high resolution, space may not be enough, in which case you should consider buying an additional volume (from 200GB for ~$10 per year) or set up automatic cleaning of old files.
