AVM Fritz!SmartHome integration: Pull DECT 200/210 Energy Data

The Fritzbox is collecting the energy data of the DECT 200 and 210 devices.
On the router configuration page there is a convenient plot showing the consumed/produced energy per selected unit of time.

I know that HomeAssistant has a similar feature to compute the delta per selected unit of time in a dedicated sensor, however I would like to access the data collected by the Fritzbox directly.

Is it possible to fetch this data and make it available as an additional entity/attribute of the respective 200/210 sensor?
