Data aggregation

Problems
#1

Hi,

I have an Efergy monitor system with three probes: one for solar production and two for consumption (two separate power lines).
I wanted to combine consumption data coming from the two consumption probes in pvoutput.
So, I configured the second probe as secondary device in the settings.
Generally speaking the output seems ok but I noticed that very often date reported is inconsistent (values reported are lower than the sum of the two consumption values).

Any ideas?
Is it correct to configure the second probe as a secondary device?

Thanks in advance to all.

The configuration is ok, it will sum PWER.804033 and PWER.789221 power values with the same timestamps as reported by Efergy.

Where are is the sum figure being compared to?

#3

Hi, I compare data from pvoutput to data from Engage web platform where you can export detailed reports (csv format, 1 minute sample).
I know that pvoutput minimum sample is 5 minutes, but I generally compare periods where consumption is quite steady…

All the data samples provided by Efergy is averaged into 5-minute intervals, so it may never match exactly.
