Home akku charge/discarge ist mixed up

[FauthD]

Hi,
in evcc charge/discharge is mixed up. Please see #30202 in evcc.
Another user gave this answer:

"Your HA sensor of the battery uses the wrong sign.
Charging must be negative."

In my case I could fix it by directly connecting evcc to the PV-converter (Sigenergy).
Since values in HA show up correctly, I assume there is an issue with reported polarity in ha-evcc.

Many regards, Dieter

You can always use a template sensor to revert the sign of any value... there is IMHO no general rule how a battery is providing power data (negative when discharging - but could be also positive! - depending on the vendor)... so to make a long story short: I don't see anything that I would be able to provide?!

Thanks Matthias,
just wanted to mention it. So others can find it as well.

EVCC did not work at all and discharged the batterie. Took me a while until I found to root cause.

Many regards, Dieter
