Haylou’s modern wearables have become incredibly popular due to their excellent price-performance ratio. However, the process of pairing them with Xiaomi smartphones or other Android devices often raises questions and technical difficulties for users, many of whom are faced with the fact that the device is not found or training data is not transmitted to the application.
Proper synchronization is the foundation of a sustainable smart home and health ecosystem. Without the right connectivity, you won’t be able to receive notifications, monitor sleep, or monitor physical activity. In this article, we’ll take a look at the steps of setting up, from charging to deep integration with system services.
It is worth noting that the algorithms of Bluetooth modules can vary depending on the version of the MIUI or HyperOS operating system. Therefore, it is important to strictly follow the sequence of actions described below to avoid typical errors and not waste time on repeated attempts to connect.
Preparatory stage before interface
Before you try to tie gadgets together, make sure both devices are ready to go. Charge your Haylou Solar or LS05 smartwatch to at least 30-40%. Low battery power can cause the Bluetooth module to go into power-saving mode and become invisible to scanning.
It is also critical to clear the list of previously connected devices if you have previously tried pairing unsuccessfully: Go to your Xiaomi smartphone’s Bluetooth settings, search the watch name (usually Haylou Solar or Haylou LS05) in the list, and click the Forget device or gear icon to break the connection.
Don’t try to pair solely through the Bluetooth system menu of your smartphone. This is a common mistake that causes the watch to connect like a headset but not transmit health data.
- 🔋 Make sure the charge of the watch is more than 30% for stable operation of the module.
- 📱 Remove old watch entries from Bluetooth list in phone settings.
- 📶 Turn on geolocation (GPS) on a smartphone, as it is needed to search for devices BLE.
- 🔄 Restart your smartphone before starting the procedure to reset network services.
☑️ Readiness for synchronization
Installation and configuration of the Zepp Life (Mi Fit) application
The main tool for managing Haylou devices is the Zepp Life app (formerly known as Mi Fit) from the official Google Play store or the App Store. In some regions, Xiaomi may need to change the region in the Mi Account settings, but most often the app is available by default.
Once installed, start the program and log in to your account, and if you don't have a Mi Account or a Zepp Account, you'll need to create one, which is a must, because without authorization, you can't synchronize your health data. In the process, enter the real data so that the calorie and step calculator works correctly.
It is important to give the application all the permissions you request. Android can block background work, so when you have requests for access to location, notifications and background activity, be sure to choose Allow. Without this notification from messengers, the clock will not appear on the clock.
💡
When installing the Zepp Life app, immediately add it to the battery exception list (Sun Run) so that the MIUI system does not close the synchronization process.
The process of connecting the clock to the smartphone
Open the Zepp Life app and go to the Profile tab at the bottom menu. Click Add Device and select the Watch category. In the list that appears, find your model, such as the Haylou Solar LS05. If the model is not found automatically, you can search by name.
The scanning process will start. At this point, a request for confirmation of pairing (key icon or tick) may appear on the watch screen. Press the confirmation button on the watch touch screen or use the side button if the model provides for it. The process takes 10 to 30 seconds.
Once the connection is successful, the app will offer to update the firmware of the watch. It is strongly recommended to agree to the update, as new versions of firmware often contain corrections for Bluetooth stack errors, which improves the stability of the connection.
Setup of permissions and notifications
To make Haylou smartwatch a full extension of your smartphone, you need to set up notifications correctly. Go to the device profile in the Zepp Life app and find the Application Notifications section. Here you need to manually activate the switches for the desired programs: WhatsApp, Telegram, Viber, SMS and calls.
Xiaomi's MIUI-enabled smartphones have an aggressive power saving system. To keep notifications stable, you need to go to your phone's settings, find the Zepp Life app, go to the Battery section, and select No Limits mode. Also, in the Other Permissions section, enable display over other windows.
If notifications still don't arrive, check to see if access to notification history is blocked. In modern versions of Android, you need to give the app the right to read notifications from other programs, a critical point for users who rely on the watch as their primary means of communication.

Compatibility table and model codes
Different Haylou watches may have different identification codes and operating system version requirements, and below is a table with the main characteristics of popular models that are often confused when searching for drivers or instructions.
| Model clock | Code in Bluetooth. | Annex | Android version (min) |
|---|---|---|---|
| Haylou Solar LS05 | Haylou Solar | Zepp Life | 5.0 |
| Haylou Solar Plus RT3 | Haylou RT3 | Zepp Life | 6.0 |
| Haylou LS02 | Haylou Watch | Zepp Life | 4.4 |
| Haylou GST | Haylou GST | Haylou Fit | 5.0 |
💡
Please note: some new models in the series GST or RS They may require a separate Haylou Fit app, not Zepp Life. QR-code.
Solving Connection and Synchronization Problems
If the standard procedure failed and the Haylou watch did not sync, try resetting the network settings on your smartphone.This action will delete all stored Wi-Fi networks and Bluetooth pairs, but often solves the problem of "invisibility" of devices. → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth.
Another common cause is Bluetooth version conflict: Make sure the watch doesn’t activate Phone Only or Pairing Mode if you’ve previously connected it to another phone. Complete factory resets through the device menu or by holding down the power button.
⚠️ Warning: If you don't see the watch again after reset, try connecting it to another smartphone. If you don't see it there, the watch's Bluetooth module may be defective and warranty repairs are required.
Xiaomi users with MIUI 12 and above sometimes face a problem when the system blocks the background search of devices, in which case it helps to temporarily disable the battery optimization for the Bluetooth system process, and do this carefully, through the Developer menu, if you are confident in your actions.
