Low consumption displayed on BMV 712 smart

I've connected a BMV 712 to the 2 AGM batteries in my Hymer motorhome, and also connectedit to the starter battery.

The voltage and percentage are displayed correctly. But the consumed amperage is very low. When I turn on all the lights and let my satellite dish search at the same time, the BMV712 indicates a consumption of approximately 0.6A.

When I start the engine or when the battery charger is on, a charging capacity of approx. 8A is indicated

Everything is connected according to schedule. What could be the cause of this low consumption indication here?

Please check the wiring again and maybe make some pictures of the installation.

There are many questions like yours in the community and in most cases it was a wiring issue.

Is it during the day - the difference may be being picked up by your solar? example - Load = 10A, solar is producing 6A so draw from battery is 4A?

No, he was inside at the time. Moreover, if there are no users, it indicates about 0 Amps, so there is no charging.
