In this node, there is an option titled Energy AC2in to AcOut kWh.
In my mind, this should read how much energy is coming in to the inverter, and is being passed thru to loads, but that is not what I am seeing. It is a very static number, that has changed once since observing it, but I cannot correlate it to anything I see on the dashboard.
I am currently bringing in between 10s and 20w, and outputting that similar value with a 3-4w delta. This input value is currently 0.10922…., dividing by 1000 gives me 109watts. As static as this number is, I have also ruled out a cumulative number for the day, etc.
