Where to find BMS parameters?

[stormbreaka]

Hello, in the config file (eye_p3.yaml) is also the BMS parameters listed (as attribute under SoC of battery 1):
attributes:
[
"Battery Corrected Capacity",
"Battery BMS SOC",
"Battery BMS Current",
"Battery BMS Voltage",
"Battery BMS Other Symbol",
"Battery BMS Charging Voltage",
"Battery BMS Discharging Voltage",
"Battery BMS Charging Current",
"Battery BMS Discharging Current",
"Battery BMS Max Charging Current",
"Battery BMS Max Discharging Current",
]

Where can I see them in HA? I can see no entity for these values. I hope you can help me to find these values.

Hi, can you pls also help me for retrieving this information's? If i press "Battery", i get the Chart, and below the chart the Option "Attribute". When i open these attributes, i only se "Nominal Voltage" (51) and "Life Cycle Rating" (6000).
I would like to use the BMS Current in my automations and statistics. I did not find this Value (Sensor?) Can i activate this for my automations?
I don't find the "Nominal Voltage" and the "Life Cycle Rating" in my entity's. And none of the BMS... values.
The original Inverter App "Solarman Smart" shows the BMS Current with the right value.

Hello, how is the "Corrected Capacity" calculated for a battery?

[rthsw]

Multiply the nominal Voltage by the nominal Ampere in h, most named Ah.
A LiFePo4 Battery has a nominal Voltage of 3.2 Volt, and some of them are rated with 200Ah. 3.2 x 200 = 640 Watt.

I'm wondering if there is some possibility to get each cells voltage or at least diff voltage for them from Solarman?

Hi @vytya, currently only for three-phase devices and only w/ batteries from Deye.
