Hello every body,

I am a new user and I am planning to use the device D103 to monitor production and usage of solar and grid energy.

I will use API’s and PERL scripts to receive data from the device.

Then load the data into Round Robin Database and use RRD graphing capability to generate PNG graphs to display.

The issue I see (and this is also on MAIC dash board)  is that the energy values are all time cumulative (they always increase) so in order for me to know how much energy was generated/used in a day/month or year, I need to save the value at the end of the previous period (day/month/year) and subtract from the every increasing counter.

Is this so? Or there is a way to see daily/monthly/yearly values? The graphs buttons only change the data resolution not the amount of data entering in the period.

Is there a way for me to program a dashboard to display energy produced used in a day?

Also the amp dial widget when there is a reverse current do not show reverse/negative value, they always show positive values even if the reverse current flag is active. Is this a bug or intended behaviour? How to display negative value for reverse current?

Thank you for your help

Kind regards

Fabio

Hello everybody,

I am trying to use complex function in a widget.

I.e. make a simple calculation to have current with a sign (d.W1-drW1)/d.V1 but I get a NaN result (not a number).

I thought I was using incorrect syntax so I used the example in the Kb  just by dividing d.W1 /1000 and I get a NaN result too. But d.W1 displays correctly if used without operators.

Is there a problem in the complex function calculation?

Thanks

Fabio

Hello,

Is it possible to write out the total consumption of the last 24 hours regardless of the current time?

I see that it is only possible to write the time of the day, which starts again from midnight.

This is also the case in the hourly breakdown, it restarts at a new hour, but I need, for example, the last 60 minutes regardless of the time.

Is there a formula or script for this?

Sorry for my English.

Have a nice day.
