Has anyone implemented RRD tools to graph their consumption, like this:-

Must be fairly easy for someone to add/setup to a raspberry pi emonscms system.....I just wish I had the skills!

I will give it a go, but it will take me months for sure!

It seems like a much lighter, faster smarter way of logging the data long term.
