Device Binding Mode

Last Updated on : 2022-03-02 01:52:39download

What is device binding?

Device binding is binding a device to an account. After you bind a device with your account, you can manage and view the status information of the device. If another account is bound with your bound security camera, the user can view the video recorded by your camera.

Tuya provides different device binding modes depending on various application scenarios. If you have enabled the strong binding mode, a bound device cannot be bound with another account before unbinding from the previous account.

What is the difference between binding modes?

The Tuya IoT Development Platform supports three different binding modes. They are weak binding, medium binding, and strong binding.

Weak binding

Weak binding is a binding mode with the lowest security level. In this mode, if you have already bound a device with your account, another user can perform network pairing and bind the device with his or her account without your permission.

Medium binding

Medium binding is a binding mode with an intermediate security level. In this mode, if you have already bound a device with your account, another user can perform network pairing and bind the device with his or her account without your permission. But you will receive notifications on the app.

Strong binding

Strong binding is a binding mode with the highest security level. In this mode, if you have already bound a device with your account, another user cannot bind it with his or her account unless you have unbound the device from your account.

Strong binding can fully guarantee the security of devices. But for manufacturers, when customers ask for a refund or exchange, the device must first be unbound from the previous account. To improve work efficiency and reduce costs, Tuya provides Unbind Devices in Batches.

How to configure different operation modes

When you are developing a TuyaOS product with a custom solution, in the step of Function Definition, you can edit Device Binding Mode in Advanced Functions. If the function is not enabled, the mode is set as weak binding by default. If the function is enabled, the mode is set as strong binding by default. You can click Edit and select Medium Binding.

Due to product properties, some products do not support setting the device binding mode. You cannot find the function in product development.

When the function is enabled, you can click Edit to select either strong binding or medium binding.

How to select a suitable device binding mode

For products that require high security, such as cameras, NVRs, DVRs, and door locks, we strongly recommend you select the strong binding mode.

For products in other categories, you can select the binding mode as per the product properties. If a product involves security and personal privacy, we recommend you select the strong binding mode.
