Hi I am currently successfully uploading my data at 5 minute intervals,
The issue I am having is I am averaging my CT data on the incomer and my generation CT then doing some math to determine the generation and consumption.
On a whole it works reasonably well but when I compare the import/export values to my electricity meter I get a different story.I have found the reason for this is related to the averaging as during a 5 minute period the sun may drop off for say a minute or two and I start to consume power from the grid but as the data is averaged this consumption is not recognized.To combat this I feel it is necessary to upload the the import export values independently. Presently I write v1,v2,v3 &v4 in a single write every 5 minutes, do i need to do an addition write after this to write the import and export values to v2 & v4 with the additional parameter n=1 t to load the import export values?
I’ve tried reading the documents but it is unclear !!!
Do I send the import /export in watts per 5 minutes or a cumulative kWh of export and import.The doc states v2 and v4 are in watts but I would think Kwh is more correct???
Really confused on how to do this and don’t want to break what I already have either!!!
Any gurus feel free to jump in
