My arduino uno sends data from my energy meter (counting pulses) to emoncms every minute. Or to be more precise, when the next pulse occurs after 1 minute. The sum of kWh on emoncms is correct (daily use). But when I try to export it to CVS for further analasys, the sum is not correct anymore. I get the best results if I choose 10s interval, but the sum of kWh is stil a few percent off.
Can you attach a screenshot of what your data looks like? how many gaps do you see?
You could use the wh_accumulator process which will join across gaps, which may solve your problem. You could keep both your current approach and add a wh_accumulator to test if you like.
