How to add static parameters into the message?

Using plugins to add new fields into the device messages.

The "item-fields" plugin type is used to add static fields to the designated devices.

Click on the "+" button in the Telematics Hub -> Plugins section to create a new plugin:

flespi panel telematics hub plugins

Let's define a new plugin for devices that will add a customer_id field that is a positive integer and a required field:

add new plugin add message field type

Note: by default, the plugin fields will be added and stored in the message and telemetry (edit the "store" setting to change that behavior).

Then we need to assign this plugin to the right devices. Go to the Plugins tab for the required device and click the "+" button:

assign plugin to flespi device

And then you should be able to see the new field in the new device messages. Go to the Logs & Messages tab for the given device to check:

field added to message in logs

Done.
