Hello  Neni84, I will take a look at this to see whats happening, although slightly different to the issue here I think it will be closely related https://openenergymonitor.org/emon/node/12414, are you recording power_to_kwh feeds too using the PHPFina feed engine? these are recommended and have better timezone support.

Hello Trystan, thanks for the quick response.

I have energy meter with incremental kWh, and i use kWh to kWh/d process for calculate the kWh/d  with PHPFina engine (see png attached).

What I do not understand is that the data are present, it looks like a display issue with the graphical bar graph ...

Tell me if I can control more ... log ... eccc

Thanks

Great, the best input processor to use in this case is the wh_accumulator, it will generate an ever increasing kWh feed from which daily kwh data can be calculated on the fly using the approach described here: https://openenergymonitor.org/emon/node/12308

On a technical note, it should be possible to use the log_to_feed in your case but if there are any gaps in the data it will record null values which will cause problems for the calculation of kwh per day on the fly. The wh_accumulator does not record these null values it instead joins across any missing data and so will generate the correct output. Ideally this should be an option available for the log_to_feed option but at the moment the way to get this is the wh_accumulator process.

Hi,

Tell me if I understand correctly :-P

Do you recommend to use for daily energy Wh accumulator  instead of kWh to kWh/d?

I have kWh total for my Modbus meter, How configure feed for daily production?

Wh accumulator - PHPFina - which interval???(1d???)

thank you so much

Neni

So in summary:

if the data for emoncms come from an energy meter Modbus how should I configure the feed?

I have 2 data that interest me power (W) and total energy (Wh).

power => log to feed

Total energy to get the daily energy => Wh accumolator (PHPFina - which interval???)

thanks
