Hi @marcoslater - I’m coming late to this discussion, and as an utter newbie so far as emoncms is concerned.
But I share your interest in seeing those graphs of W and kWh vs time. Especially cumulative kWh, a.k.a. meter reading (the bar chart of daily kWh not so much - if desperate, I’d label the power axis kWh/day). I would have an idea how to get from pulse sensor output to such graphs were I doing the processing off-line, but my ignorance of how emoncms does its stuff makes me hold my tongue (for now?).
Cheers!
