Hello, i configured an SDM630 on HomeAssistant using modbus.
The sensors work well and I can display them in HomeAssistant.
From what I can see, the total kWh adds both import and export. I would also like to show the net total which is import - export. I searched in the manual and I can see that Net kWh exists. Screenshot - 1433bbb878d961f04c4324b74d69e6b0 - Gyazo
I tried adding it in my configuration.yaml file same as other sensors but I can’t manage to figure it out. Right now it displays 0 total.
As you can see down, I tried adding Net kWh by hand since it is not in the full sensor list I have. What can I do to add it correctly and see the Net kWh?
