Home akku charge/discarge ist mixed up

[FauthD]

Description

Hi,
evcc thinks it charges the akku while in reality it discarges it.
You can see that in the dashboard of evcc (I made screenshots).
Currently it charges with ~2.5KW, but it shows as discharge.
Perhaps the issue is located in the sigenergy integration?

Or can I misconfiger it?
Thanks, Dieter

Steps to Reproduce

1: Check battery status in Home Assistant
2: Open the evcc dashboard (home)
3: See that charge/discharge is mixed up

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

Hi VolkerK62,
thanks!
To keep the equations smaller I changed to direct connection to the sigenergy converter (before I had used the Home Asistant connection).
Took a few restarts and browser refreshes, but now it looks good.

So I supose the issue lies in the HA integration. Will report there as well
