That is what I do.
On graphing, looking at short periods of time can be odd. Also, unless both Feeds started at exactly the same time put one on left and one on right but check the scales are the same else you get some odd views. This is 2 feeds (pulse and CT) started about the same time.
This is 2 feeds started at different times - note the scale is different.
If I force the scales to be the same…
You can see the CT over reading.
If you look at the stats…
You can see the ‘Diff’ that is a the measured kWh in the frame. Missing data on the pulse will be when the rate of change means I do not get a pulse within the 10s window.
