FEATURE REQUEST: Home battery integration through sensorbox CT clamps

[RobertJansen1]

Is your feature request related to a problem? Please describe.
Would it be possible to use the sensorbox to measure the current a home battery is charging / discharging to deduct from the p1 information?

Describe the solution you'd like
Add the possibility to both use p1 and ct clamps on a sensor box in order to integrate with a home battery

Describe alternatives you've considered
alternative would be to gather information and feed it through but that would depend on numerous systems translating / forwarding the data

Additional context
Add any other context or screenshots about the feature request here.

You are aware of the possibility to feed the battery currents via the REST and MQTT APIs?

[RobertJansen1]

Yes i am aware but I would prefer "hardwiring" the information as that is more reliable and faster

What kind of battery do you have? Does it have a direct AC connection?
As the current transformers can only measure AC current, not DC.

For directly measuring DC currents going into/out a battery other (hall) current sensors are needed.
Unfortunately these are incompatible with the sensorbox, as they require an external voltage to operate.

so just ac ct clamps would work, and i also want the p1 metering to measure smart charging, but on top of that i want to exclude the battery power usage if that makes sense :) an alternative would be to substract a fixed 10kw (as it is mostly discharging with 10kw) when the delivery to the net is higher than 10kw
