I’m using SONOFF POWR316 to monitor my solar generation (Power, Current, Voltage and total kWh). Does ewelink only measure power consumption or does it recognize power generation sonoff devices? Which leads to my next question. Does my solar power generation sonoff device add or deduct to my total monthly consumption?? Thank you

How did you wire this up? When I tried the same I found that when the switch lost power in the evening it would not start up again in the morning, since the panel inverters need to sense their connection to the power grid.
