How to connect Xiaomi thermometer to Alice: full instructions with pictures and tips

Voice assistant Alice from Yandex has long ceased to be just a “smart speaker” — now it controls the entire ecosystem of the smart home, including climate sensors. But many users face the problem: how to get Xiaomi thermometer (be it the Mijia Bluetooth model, Aqara Temperature Sensor or Xiaomi ClearGrass) to transmit temperature and humidity data directly to Alice? In this article, we will examine all the working ways of integration — from official connection via Mi Home to workarounds using Yandex IoT and third-party services.

It’s important to understand that not all Xiaomi thermometers support direct synchronization with Alice out of the box. For example, Mijia Bluetooth Temperature and Humidity Sensor requires additional manipulation, while Aqara devices often work through the Aqara Hub. We analyzed the current connection protocols for 2026 and collected instructions that are guaranteed to work even for budget models. If you have already tried to link the sensor to Alice and received an error like “Device is not supported” – do not close the page: in the “Problems” section, you will find specific steps for your case.

1.What Xiaomi thermometers are compatible with Alice?

Before you start setting up, check if your model makes it to the list of supported devices. Yandex has officially certified only a portion of Xiaomi sensors to work with Alice.

If your model is not in the table, it doesn't mean that you can't connect, LYWSD03MMC It can be used with alternative scoring (for example, ATC1441 or PVVX), Then it will send the data to the server. HTTP — And Olix will be able to read them through Yandex IoT, and we will talk about this in detail in the section about workarounds.

⚠️ Note: Yandex periodically updates the list of supported devices. Before buying a thermometer, check for its presence in the official register of compatible gadgets. For example, in 2023, Aqara support was added. FP2, Older models like Xiaomi V1 They were left without formal integration.

2. Official connection via Mi Home (for supported models)

If your thermometer is on the list of Alice compatible (see table above), the easiest way is to link it through the Mi Home app.

1. Install the Mi Home app (available for Android and iOS) and log in with your Xiaomi account.
2. Add a thermometer to Mi Home: 📱 Open the app and press. + → Add the device. 🔍 Select the category "Sensors" → "Temperature and humidity". 🔄 Follow the instructions on the screen (usually you need to press the button on the sensor).

Check the sync:

• 🗣️ Ask Alice, “Alisa, what is the temperature in the room?".
• 📊 Or check in the Yandex application (section "Smart Home").

⚠️ If Alice does not see the thermometer after synchronization, check it:

• 🔄 Update the sensor firmware in Mi Home (Section "Device settings").
• 📶 Make sure the thermometer is within range of the Bluetooth hub (if used) or router (for Zigbee).
• 🔒 In Mi Home settings, allow data transfer to third-party services (Profile) → Settings → Applications and services).

• 🔹 Aqara Hub M2 — Supports up to 128 devices, and works via Ethernet.
• 🔹 Aqara Hub M1S — Budget version with Wi-Fi connection.
• 🔹 Xiaomi Mi Smart Home Gateway is outdated, but still available for sale.

The setup process:

1. Connect the hub to the network: 🔌 Insert the hub into the socket and wait for the indicator to flash. 📱 Open the Aqara Home app and add a hub through + → Add the device.
2. Add the thermometer: 🔍 At Aqara Home, click + → Temperature and humidity sensor. 🔄 Press the button on the thermometer (if required).

Get Alice on the phone:

• 🌐 At Aqara Home, go to Profile → Settings → Integration → Yandex.
• 🔗 Log in and allow access to devices.

After synchronization, the thermometer will appear in the Yandex app and be available for voice commands, for example, you can say:

• 🗣️ "Alice, turn on the heater if the bedroom is below 20 degrees".
• 🗣️ "Alice, what is the humidity on the balcony? (if the sensor is installed there).

💡

If Alice doesn’t recognize the name of the room (for example, she says “I don’t know where the bedroom is”), open the Yandex app, go to the Smart Home. → Settings → Rooms and assign a sensor to the desired room.

4. bypasses for unsupported thermometers

If your Xiaomi thermometer isn't on the Alice-compatible list, don't despair. There are several workarounds:

Method 1: Firmware alternative software (for LYWSD03MMC similar)

Models like Xiaomi LYWSD03MMC You can reflash it to custom firmware, which will send data to your server or to the cloud:
