Hi, I have one input channel configured to store an power meter’s energy reading. The reading gives me cumulative kWh every 1 minute. I managed to read and show the cumulative kWh every minute interval time on table.
Now I want to further process the cumulative kWh data to become instant reading of how much kWh used within one minute (current kWh data – previous kWh data) . I want to create another input channel which can process for this request and show in table.
Pls advice for the formula to perform this request.
