Let me say that Hubigraphs is just amazing work.
So, I want minimal traffic, minimal repetitive data, but useful graphs.
Here, I am trying to graph the watts consumed on certain plugs on a Greenwave PowerNode 6.
It is configured to only report when power consumption changes by 10% or more.
The problem with this is that the resulting line graphs are wacky - the stereo was turned off at 11pm, and left off until 10am. The resulting graph makes a ramp from zero watts at 11pm up to full power at 10am. There seems no way to get Hubigraphs to NOT create this ramp. If I use a bar graph, it shows a single bar when a device is first turned on, but never shows when it is turned off.
Is there any way to provision it for these data points that assume a knowledge of a stable value of the LAST reading until the next?
