I made a simple power meter a few years ago from a ted1001 I just reused my info from there and inserted into here
here a sample shot of the last 10 minutes as I only had it running to a couple hours…
Here a copy of pl file to capture mqtt to rrd and some explanation of the workings. plus my old ted project where you can grab the shell scripts to create the historical data you want you just need to edit them a little to work with what ever configuration you have

– next on the agenda to build wireless solar panel monitors and pwm that tell the volts and amps of each panel and incorporate into my GTI sketch. to power back panels when not required ( but I think that might be a winter project as I got alot on my plate and I running out of time)… but in a few days or so I will upload how to install and configure the IoT that I am using … – currently for this i am just using an old acer mini laptop running ubuntu . then once that is working fine on there I will move it over to a orange pi( raspberry pi compatible)
