| [HUAWEI] The air pressure or altitude data on my watch is inaccurate |
Air pressure and altitude data is calculated based on the ambient air pressure measured by your watch's built-in barometer, and the local air pressure benchmark obtained from the Huawei Health app. As a result, the air pressure and altitude will vary depending on the environment.
- If the air pressure fluctuates due to changes in the environment (for example, an air conditioner or a fan is turned on), the altitude measurement may also be affected. Try to measure the air pressure and altitude levels in stable-temperature and low-wind environments.
- In some coastal areas and basins, the actual altitude may be below sea level, which causes displayed altitude value to be negative.
- Considering the screen size, the altitude curve updates once every 20 minutes, and therefore changes over short periods of time may not display.
If the issue persists, perform the following steps to troubleshoot:
Check the air pressure hole on your watch
Start a measurement in a flat place without wind. Do not block the air pressure hole on your watch.
If the air pressure hole on your watch is blocked by foreign objects or liquid, the measured air pressure and altitude level may be inaccurate.
Check the air pressure hole by playing a ringtone or song on your watch to determine if the sound is clear. If you suspect that the hole is obstructed, hold your watch with the air pressure hole facing downwards, and gently wipe the hole clean with a soft brush, or dry the hole if it is wet.
For details about the location of the air pressure hole, see Appearance and structure of smart watches.
Grant the location permission for the Huawei Health app
For optimally accurate altitude data, allow the Huawei Health app to always access your location information from the app permission management screen on your phone.
Check the connection status of your watch and your phone's network connection
If your watch is not connected to your phone, or your phone is not connected to a network, the air pressure data may fail to update in a timely manner due to delayed obtainment of local benchmark air pressure.
Make sure that your phone's network connection is stable, and promptly connect your watch to your phone. You can also swipe down on the home screen of the Huawei Health app to sync data. Your watch will then obtain the latest local air pressure benchmark, and use this information to reduce the measurement error.
If the error exceeds 50 metres, it is possible that the air pressure provided by Weather is abnormal. In this case, provide a video (recording the process that starts from linking your watch with the Huawei Health app and ends with viewing the air pressure and altitude), and collect logs of your watch and the Huawei Health app (beta version), to escalate the issue to the Huawei Health technical support team.
Manually calibrate the altitude
- Press the Up button on your watch to open the app list and select Air pressure.
- Swipe up on the screen until you reach the altitude screen, and touch Calibrate at the bottom of the screen. (If there is no Calibrate option displayed, it means that your watch does not support manual altitude calibration, such as the HUAWEI WATCH 3 Series devices.)
- Enter the correct altitude and touch OK.
If the issue persists, or the air pressure value displayed on your watch does not change or no air pressure value displays, the barometer on your watch may be faulty. In this case, take your watch and proof of purchase to a nearby Huawei Customer Service Centre for assistance.
