The EMnify User Interface (EUI) enables you to control the amount of money spent by a single device each month. In order to set a monthly prepaid balance, first you need to activate the option in the Service Profile (part 1) and then configure it in each endpoint using this tariff profile (part 2).
1. Prepaid balance activation in Service Profile
In the EUI, select one Service Profile under "Service Profiles". In the "Basic Configuration" tab, you can activate the Prepaid Balance option:
Don't forget to save the configuration before going to the next step.
NOTE: All devices using this service profile will have the "Prepaid Balance" option activated. Make sure to configure it for each device otherwise their balance will be 0 and they will not be able to setup a connection.
2. Prepaid balance configuration for each endpoint
Select an enpoint you wish to set a prepaid balance to. In the "Configuration" tab of the endpoint, select the configured "Service Profile".
Save the configuration.
You should now see the new "Prepaid balance" tab. Click on it and select "+top-up Balance" to add a new balance. You can set here the monthly limit for this endpoint and also choose to reset the balance at the start of every month.
