What are Device number, UUID and Device ID?

• Device number is a 4-5 digit number serial generated based on the manufacturing sequence.
• UUID is short for Universally Unique Identifier, which is the true unique identifier for each device.
• Device ID is the last four digits/letters of UUID.

Both UUID and Device ID are printed on device housing or sticker.

For many years, we used Device number on our data platform to provide an easy way for users to refer to their devices. However, Device number cannot be printed on device, thus caused confusion when users are trying to identify their devices without using App.

To solve this problem, we update our data platform to gradually change to the UUID/Device ID display mode instead of Device number. For the transition period, Device number will still be available. We recommend that all users to change to the Device ID mode and use Device number as a reference when necessary.

To switch among device number, UUID and device ID, do the following:

• Ecotopia Data Center
  In the device list, click the icon as shown below.
  
• Ecotopia App
  In the animal list or device list, click the icon as shown below.
  
  Note: In Ecotopia App, UUID is always displayed. So you can switch between device number and device ID.
