Xiaomi Mijia Temperature and Humidity: a complete guide

Modern wearables have long since ceased to be just time-reflection devices, becoming powerful tools for monitoring the environment and health. Xiaomi Mijia Temperature and Humidity Electronic Watch stands out from the competition with built-in high-precision sensors that can monitor climate parameters in real time. For owners of the smart home ecosystem, this device becomes an indispensable assistant, allowing you to control the microclimate indoors right from the wrist.

The process of initial activation and pairing can seem confusing for beginners who are faced with the interface of the Mijia or Mi Home application. Errors at this stage often lead to the inability to receive data from the sensors or the absence of push notifications. In this article, we will analyze in detail each step necessary for the correct operation of the gadget, eliminating typical compatibility problems.

It is important to understand that the functionality of the watch depends on the regional binding of the account and the firmware version. The Chinese version of the device may require additional actions to fully integrate with global servers. Following the recommendations below, you will be able to unlock the full potential of the device and enjoy accurate measurements of temperature and humidity.

Primary preparation and activation of the device

Before syncing with your smartphone, you need to make sure that the electronic watch is charged at least 20-30%. Long-term storage in a warehouse could drain the battery, so connecting to the charger for 15-20 minutes will be the best solution.

After the inclusion on the screen should appear a welcome screensaver with the logo of Mijia and QR-If the screen doesn't light up, press the side button on the 3-5 In some cases, you need to remove the protective film from the charging sensor, which can block contact.

⚠️ Note: Do not use chargers with higher current 1And (5V/1A), Because it could damage the watch's power controller. USB-Computer port or certified adapter.

To activate the climate monitoring functions, you need to wake the device up. The temperature and humidity sensors start working immediately after switching on, but to transmit data to the phone, you need to complete the pairing procedure. Make sure that the watch has the current interface language if the model supports multilingualism.

Installation and configuration of the Mi Home application

The foundation for managing the gadget is the official Mi Home app (or Mijia depending on the region), download the program should only from official Google Play or App Store, avoiding third-party resources where you can find modified and insecure versions of the software.

When you first start up, the app will request an account or login to an existing one. It is critical to choose the right region when registering. If your device is designed for the Chinese market, you must set the China region in your profile settings, otherwise the gadget may not be determined in the list of available for addition.

Once logged in, go to the Profile tab and make sure that geolocation permissions and Bluetooth are active. Geolocation is necessary to correctly identify the clocks near the smartphone, especially on Android devices 6.0 and higher. Without that permission, the search for the device can go on indefinitely.

In the application interface, press the button «+» In the upper right corner, you can add a new device. QR-Check the device automatically, make sure your smartphone is connected to 2.4GHz Wi-Fi, as smart home devices rarely support the 5GHz standard.

The process of pairing a watch with a smartphone

Direct communication between the phone and the watch is established using Bluetooth Low Energy (BLE) protocol. When searching for a device, keep the smartphone at a distance of no more than 1-2 meters from the watch, the smartphone screen should be unlocked, and the Mi Home app is open in the foreground.

When the app detects the Xiaomi Mijia Watch, a request for confirmation of pairing will appear on the screen. A window may also pop up on the watch screen asking you to confirm the action or enter a code. Click "Confirm" on both devices to establish a secure connection.

When you install the connection, you may need to update your firmware, which is a regular situation, because the software version often contains bugs or does not support new features, and wait until you finish downloading and installing updates without closing the application or going too far from the clock.

⚠️ Warning: Interrupting the firmware update process may cause the device to fail in software (brick) and make sure that both devices are over 50% charged before starting the procedure.

After successful pairing, the app will have a device card with current sensor readings. If the data is not updated, try removing the device from the list and repeat the procedure by pre-resetting the clock to factory settings through the device menu.

Calibration of temperature and humidity sensors

One of the key features of this model is that it is highly accurate, but it may require initial calibration to achieve it, and the temperature and humidity sensors are sensitive to extreme changes, so once turned on, the device takes 10-15 minutes to stabilize the readings in the new conditions.

To check the accuracy, place the watch next to a reference thermometer or hygrometer. If the readings differ beyond the permissible limits (usually ± 0.3 ° C for temperature and ± 3% for humidity), a software correction function may be available in the application. This option is located in the settings of the particular device in the "Additional" tab.

Keep in mind that the watch body and the heat from the wearer’s hand can affect the temperature sensor readings. To obtain the most accurate temperature data in the room, it is recommended to remove the watch from the wrist and place it on a horizontal surface away from heat sources.

Humidity is measured through special holes in the body that should not be covered with dust or moisture. Regularly wipe the back panel and touch areas with soft dry cloth. Fogging of the sensor from the inside is possible only at extreme temperature changes, which is a marriage.

Configuring notifications and interface

The smartwatch’s functionality is not limited to climate monitoring, but can stream notifications from instant messengers, social networks and phone books. To activate this feature, go to the profile settings in the Mi Home app and select “Application Notifications”.

In the permission list that opens, activate the switches opposite the desired programs (WhatsApp, Telegram, Viber, etc.). Please note that on Android, for the correct operation of notifications, you must provide the Mi Home application with permission to “Master on top of other windows” and access to the notification history.

The face interface is also customizable. On the device card, select Dials (or Stores) to download new designs. Many dials support displaying temperature and humidity data directly to the main screen, eliminating the need to open the app.

For users who appreciate minimalism, the Do Not Disturb mode is available, in which the watch screen goes out and the notification vibration is turned off at a given time, for example, during a night's sleep.

Solving Typical Problems and Troubleshooting

Users may encounter a number of technical difficulties during operation, the most common problem is the disconnection of the Bluetooth connection. If the watch periodically loses contact with the phone, check whether the restriction of background activity for the Mi Home application on Android or iOS is worth it.

Another common complaint is that time is incorrectly displayed. Since the watch syncs time from your smartphone when you connect, make sure the phone has automatic time synchronization over the network.

If software methods don't work, you can reset the device completely. The watch case usually has a hidden hole for the Reset button or a combination of buttons to log into the engineering menu. Factory Reset will return the device to factory settings by removing all user settings and data.

💡

If you have frequent communication breaks, try “forgetting” the device in your phone’s Bluetooth settings, and then re-pairing through the Mi Home app, ignoring the Bluetooth system menu.
