We had a power outage here a few weeks back that has a caused a glitch in the energydata calculated from the incoming power feeds. ie when I look at the incoming solar and import (grid) power feeds on that day (May 17) I can see a jump with no data from approx 9:00am when the power was cut through to approx 4:45pm when I fixed the date/time problem and it started recording correctly again. However, I have since noticed that there was a huge glitch in the energy feed graphs and now I have discovered that this has been caused by the import and solar energy feeds being reset to zero.
My system is a RPi3 with emontxv3 with directserial software.

Can I edit the data to re-instate the correct values?.
Thanks Jon,
That certainly had an effect on the feeds that had reset themselves. The edit process seems a bit random though. I went back to the date that the reset had occurred and corrected the first incorrect log entry and nothing appeared to have happened, however upon monitoring the current output I noticed that it had jumped up to the value I had just entered.
ie I changed the entry for 17/05/17 9:05:00 to 909.4 as per the above table, but the only thing that changed was the current value for June 7th.
I tried a few times at various date/time points and sometimes they altered the value for that point and other times it changed the current value. Maybe it has something to do with when emoncms is updating a new value.
In the end I just added an offset to the current value equal to the point just before reset and left it to run. At least the future values will be correct.
I know im digging up an old thread but, I’ve just noticed this issue when I went to pull up my July solar stats.
we had a power blink on the 27th and all the kwh feeds has reset to 0. its now a couple of days later and looking for the best way to correct the data.
I am looking at the edit real time bit, And can see that i could multiply everything in a window by a float or a fraction. - Can a constant be added or am I missing a math trick that i could be using?
Or is there something in Post process that could be used?
