Add a data source

The StrideLinx router's Digital Input will need to be added as a data source.

1. Go to Fleet Manager > Devices and click on your device name.
2. In the left menu, at Services, click on the icon and select Data source > SMTP/GPIO.
3. Enter the requested information (details below) and click on Add.

   Field	Description / instructions
   Name	Enter a name for the data source.
   Identifier	The identifier is entered automatically and ensures that every data source remains unique, even if they share the same name.
   IP address	Leave this field empty.

Add variable

Once you've added a data source, you can add the variable.

4. Under your  Data source, go to Variables and click onAdd variable.
5. Enter the requested information (details below) and click on Add.

   Field	Description / instructions
   Name	Enter a name for the variable.
   Identifier	The identifier is entered automatically and ensures that every variable remains unique, even if they share the same name.
   Type	Select Boolean.

You have now made the changes in the StrideLinx Cloud, but these are not yet active in your device. You will need to push your changes to your device for them to take effect.

6. Click on Push config to device in the top right corner.

Test variable

The variables test is recommended to check if all added variables are configured correctly. It shows the value of all variables if everything is configured correctly and shows an error if something is not configured correctly.

7. Click on Run test near the top right corner.
   • The test will attempt to update values every 0.5 seconds.
   • Is the test showing unexpected value? Check the configuration of the variable.
   • Is the test showing a timeout error? Contact your IT to make sure the test is not blocked. The test sets up an outgoing connection from your computer to the StrideLinx router using.

     Port	Transport protocol	Application protocol
     443	TCP	WebSocket
