- Make sure that the battery level is higher than 50% when upgrading the smart device. If the battery level is below 50%, the smart device can’t be upgraded.
- If the smart device upgrade fails, the app will automatically reconnect. If the automatic connection does not work, you can pull down on the homepage to perform manual synchronization. It will automatically reconnect the smart device.
- For some devices, there will be two minutes of wait time (the smart device has no response during this period). But it will automatically reconnect later.
