How to restore Tuyalink device to factory settings?

In the Tuyalink device access scenario, there are two main methods to achieve a factory reset: 1. Local reset: Triggered by the device's button or power-on count, it restores the device to the state before network configuration and allows the choice of whether to clear data. After the device is reset, it enters the network configuration state. If the network configuration times out or the device restarts, it will restore the previous network information. 2. Remote reset: This is done through application software to unbind the device from the cloud. A normal reset only unbinds the relationship, while a factory reset clears both the cloud and the device's local data. For Tuyalink access, the device side supports the local normal reset function, which unbinds the device through local buttons or power-on counts, restoring it to the state before network configuration without clearing local or cloud data, allowing for re-binding with the device. Note: For Tuyalink development, the device side does not provide a direct reset interface.
