I’ve 3 sensors: grid, solar, battery.
I’ve configured the battery charge/discharge feeds from a single sensor and I’ve managed to configure the input so both feeds are positive values, based on another post in here. They compare favourably with the inverter’s reported values, so all good so far.
In the My Solar app, the ‘Use Now’ value is configured for the ‘use’ feed. This is currently just the grid sensor, so it would seem reasonable to aggregate it with the battery_discharge feed to get a true value for household consumption.
When I try to add this logging to the battery sensor input, the value is wildly different from just adding the values of the ‘use’ feed and the ‘battery_discharge’ feed. I must be making a serious error in my configuration, but it seems logical enough to me.
Can anyone help resolve this newbie error please?
