kWh Count for charging batteries from Grid or Generator

Hi guys

Is there some way to show the kWh count for charging batteries from Grid or Generator? Can this be done via NodeRed/Signal K?

Thanks!

Hello, when i read the manual from ET112 or EM112 should both parts theoretically works for this.

But not 100% sure, how it look's on a VRM screen.

Best regards Robert

I'm using Modbus TCP with Home Assistant.

Take this for refference

Here are the Unit IDs and Addresses for your counters:

Unit ID 227 Address 76 "Energy from AC-In 1 to battery"

Unit ID 227 Address 80 "Energy from AC-In 2 to battery"

Unit ID 227 Address 92 "Energy from AC-out to battery (typically from PV-inverter)"
