Ecoflow steam PV output too high, if combined with external PV

[Metatron2k2]

Describe the bug

When an Ecoflow Stream Mini-PV is combined with a normal PV, the output is reported too high. EVCC is using the PV Sum for the display in EVCC. For some reason Ecoflow is also counting the excess Power from other PVs towards PV Sum if it would otherwise go to the grid. When both Stream PV and external PV are put into EVCC the power basically gets powered twice.

Steps to reproduce

1. Setup Ecoflow stream together with other PV.
2. Obersve the power. It can by far exceed the maximum power of the panels connected to the Ecoflow Stream

Can you please analyze where the proper value is located on the device?

[Metatron2k2]

Yes, already figured most of it out. It seems like it is not published on the REST API at all. I currently have a working version of it using the MQTT API, which also takes care of having multiple Batteries in you Stream setup. Give me a day or two to test it. I'd probably add it as a new device in a MR.

@premultiply
I created a new device and made a PR:
#29217

Let me know if there is anything I should change
