Adding a message formatter to a device product

Adding a message formatter to a device product

Instead of adding a message formatter to individual device instances, you can associate it directly with the device product. This ensures that all device instances derived from the product automatically include the message formatter by default. This applies to both imported device products and user defined device products.

Prerequisite: The required device product must be imported from the device gallery or must be added as a user defined device product before proceeding.

Note: Message formatter can be added only to device products of the smart sensor type with support for LoRaWan via LoRaWAN Datastream. For OEMs, if you need help creating a message formatter for your device product contact support@zohoiot.com.

To add a message formatter to a device product,
  1. Access the Developer Application.
  2. Select Products in the left pane.



  3. Click on the required device product. For this illustration, the device product WS302 is selected. This opens the device product's information page.



  4. Click Actions > Manage Message Formatter.



  5. Click Associate Custom Function.



  6. Click Add Custom Function.



  7. Provide the details in the appropriate fields and click Save and Associate. This will open the custom function editor.  For this illustration, a message formatter custom function called WS302 Message Formatter is created.



    Note: Display name will be the name of your custom function. Function name will be used for internal reference purposes.

  8. Provide the required custom function, in the Javascript Lite programming language, to format the received messages.

  9. Click Save and Associate to save the function and exit the editor.



  10. Click Save. The custom function will now be associated with the selected device instance.
