Actual charge rates not in HA service calls

[robertugo2]

Describe the bug For service calls the power for charging and discharging is not included. Only max/min values are included as {power}, see: https://github.com/springfall2008/batpred/blob/725c1e82ca2a78f3929e41c7f48a021528fe0250/apps/predbat/inverter.py#L2126

Expected behaviour I would expect, that the calculated charge/discharge values are passed to service call. So as you will see in logs, the caluculated charge rate is 1200W and unfortunately this value is not included as {power} value. Is it possible to add this? I tried to do that by my own, but unfortunately the code seems to be too complicated for me :( Value is successfully passed to https://github.com/springfall2008/batpred/blob/725c1e82ca2a78f3929e41c7f48a021528fe0250/apps/predbat/inverter.py#L1239 function, so maybe it would be possible to store this variable as class property, that can be picked up and set to {power}? I also see many possible workarounds (set mqtt_api to true and get charging power from there and so on), but ideally I would like to have that available in service call. Or at least as something like sensor.predbat_current_charge_power in HA, because as I see it is not exposed as sensor.

Please let me know if I can help you somehow.

Predbat version

v8.15.1 Minor fixes & improvements, new compare_active entity

Environment details

I'm using a Sofar inverter controlled by the Solax Modbus integration. Thus that I defined my inverter as "MINE" and I would like to control some helper instances in HA. My config you will find here: https://gist.github.com/robertugo2/f422316253f8a0f81760eb11633d532c
