Hello, Matt,
Thank you for your question.
Yes, it is possible to send the current of the battery to the server. All you have to do is enable the "Battery Current" I/O element in the configurator.
Here is how you can do that:
- Connect the device to the computer and connect to it using the configurator.
- Go to the IO section of the configurator.
- In the list of IO elements, find "Battery Current" and set the priority to Low.
- Save the configuration to the device.

You can also enable the "Battery Current" IO element using SMS commands by sending the following command:
<SMSlogin><space><SMSpassword><space>setparam 50130:1
If you don't have the SMS login and password set, then the command should look like this:
<space><space>setparam 50130:1
