Combined import/export value in data.json/MQTT

[jladefoged]

Is your feature request related to a problem? Please describe.
Grid import and grid export values are available in data.json, but software like OpenDTU-onBattery does only support one value and expect this value to be negative when exporting. The value is used with using the dynamic power limiter feature.

Describe the solution you'd like
Combined import/export value in data.json and perhaps MQTT as well.
Perhaps an "ie" value?

Describe alternatives you've considered
Requesting OpenDTU-onBattery to support import and export as seperate values.

This sounds like a reasonable improvement that can be useful for some users - unless someone sees a potential pitfall here?

Suggest to add an additional end point for the "OpenDTU-onBattery" feature based on current / other solutions.

I'd like some more info about this. Lets start with what opendtu is and what other integrations are like

OpenDTU-onBattery will support separate import/export values in their next firmware version, but adding support for at negative consumption value in AMS Reader might still be a good idea for other future projects. If not the feature request may be closed.
