Home Battery shows reversed charging/discharging

[Dada-1973]

Hi, absolutely love evcc and managed to set it up with some YouTube videos in German. However, I added my HomeWizard batteries via Home Assistant and despite the sum sensor for all 4 of them clearly shows negative number (e.g. -900) when they are discharging to keep the house at "zero" towards the grid, they are shown as charging at 900W. Can anyone point me to how to fix this?

See https://docs.evcc.io/en/docs/reference/configuration/meters

evcc uses positive (+) values for incoming currents (grid consumption, PV generation, house battery discharge) and negative (-) values for outgoing currents (grid feed-in, PV inverter standby consumption, or house battery charging).

Hi Stefan. Thank you for your quick reply. So am I correct to understand I have to figure out how to “report” the battery current multiplied by -1 and then it will show correctly?Thank you JanPS: thank you for such awesome software like evcc.  On 8 Dec 2025, at 18:04, StefanSchoof ***@***.***> wrote: See https://docs.evcc.io/en/docs/reference/configuration/meters evcc uses positive (+) values for incoming currents (grid consumption, PV generation, house battery discharge) and negative (-) values for outgoing currents (grid feed-in, PV inverter standby consumption, or house battery charging). —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you authored the thread.Message ID: ***@***.***>

I solved it by inverting the HomeWizard battery sensor I created in the Helpers of Home Assistant and now it shows correctly. Thx.
