Thanks for sharing your modifications — this is really valuable!

The Cygni 10.0HS-M8 appears to be a Dyness device with inverted current/power polarity (negative = charging, positive = discharging), which is the opposite of what i assumed. This affects the batteryStatus calculation.

Your additions from getLastRunningDataBySn are particularly interesting — PV power, load power, grid import/export, inverter temperatures and run mode are data points that I haven't surfaced yet. These would be very useful for users with hybrid inverter setups.

A few questions before I consider merging these into the main integration:

1. Does getLastRunningDataBySn return actual values for your device, or mostly nulls? (I’ve seen it return all nulls for Junior Box / DL5.0C standalone setups)
2. For the inverted polarity — is this specific to the Cygni or does it depend on inverter settings?
3. Could you download and run the updated dyness_test.py directly from GitHub? https://github.com/shopf/dyness_battery/blob/main/tools/dyness_test.py
   This version (v2) only needs your API ID and Secret — no device SN needed. This gives me an overview of the sensors, since the Cygni model hasn't been reported to me yet and I don't own one myself.

Thanks again for contributing.

Hi @StuPenTech I received some valuable PDF files from Dyness this morning and am currently working on API v2 (there could be a lot of room for improvement there).
To start with, however, I’ve expanded the test script. Could you please run v4.0 and send me the result? That would be a huge help.
Many thanks in advance.
