During the storms the other day I lost power to the house, and this appears to have done something to the use_kwh log. The log has data but the running total seems to have been reset at power lost time, right before power loss it had a value of 2178 when the system came backline it started at 0 and …

Sorry, It sounds like you’re running the emoncms master branch. There was a mistake in a recent commit which I have now corrected, could you update again? Then try powertokwh, select input “use”, name the output feed “use_kwh2” (creates a new feed which you can check before deleting the old). Depe…

Hello John, Yes there is a way to fix this, do you see a module called post process in your EmonPi setup menu? There is an issue with the module having disappeared in a recent update which I need to fix

Hi, No I do not have “post process” so am affected by it disappearing. How would I do it when it returns?

Ok, thanks to @glyn.hudson the module disappearing issue has been fixed. If you can run EmonPi update again it should correct the link. One you have it, you can use the ‘powertokwh’ post processor on the original power feed to rebuild the cumulative kwh use_kwh feed. Let me know if you get stuck. …

Hi, post process is back, although I am unsure which input to use. Create new - powertokwh Select input “use” or “use_kwh” ?? output feed emonpi\use_kwh Is that correct, how do I monitor progress as I tried the above and the create button appears but it doesnt make it to the “My Processes” list. …

Awesome, data regenerated. Many thanks for the quick responses.

great to hear! I have changed the thread title so that its hopefully easier to find for others

Hi Trystan, Can this mechanism described above be used to fix an existing use_kwh feed, instead of creating a new one? My issue is that I’m using the “Power to kWh” process on the input to log to that feed (which allows me to track instant use on the Apps). If I create a new feed in the way you de…

Continuing the discussion from Correcting cumulative kWh reset with post process module : Hello all I also have the same request as wabiloo: I recently installed emoncms locally on my Raspberry Pi with Raspbian Jessie, following the detailed guide that you provide on github. I activated the low-wr…

Hi everybody, not receiving answers, I tried to do tests independently. I tried to post-process one of the feeds that had gone to zero, creating a new feed: the script really does a good job and the data are fixed I tried to replace the reset feed with the newly created feed: – I stopped apa…

no one helps me… :slightly_frowning_face: for the moment I’m trying a mod to the function get_timevalue(): // CHAVEIRO comment: Can return NULL as a valid number or else processlist logic will be broken // Test for avoid to reset PowerToKWh process feed if (is_…
