Emonsd Dashboard reporting error

Just noticed this. Was taking a look at my dashboard to see how much my monthly usage was on my OpenEVSE charger.

When I put my mouse over the month it is reporting the total at the next months.

Unless I am mistaking it’s operation.

@emrys - one for you?

Hello @Ryan_S have you set your timezone on the My Account page? Testing here looks to be working ok.

I’ll double check that when I get home. I’m pretty sure I did, but maybe forgot when I reinstalled a couple months ago.

Took a look under my profile. Timezone is set correctly.

Thanks, ok, could you show all the options that you have set in the configuration panel for the widget?
What kind of source feed are you using? is it a cumulative kWh feed or daily kWh feed?
Are you using delta mode for the bar graph?

Figure a picture of the settings works.


Thanks @Ryan_S do you by any chance have a cumulative kWh feed of the OpenEVSE consumption (created using power_to_kwh rather than kWh/d)? This is now the recommended approach to generating daily, monthly etc graphs, see the guide here: https://guide.openenergymonitor.org/setup/daily-kwh/

You can use the post process module (pre installed on the emonSD image) to create a cumulative kWh feed from historic power data if you have not already got a suitable feed.

I actually am creating mine from the amps output from OpenEVSE. I didn’t like the Wh output and just decided to calculate it from the amps multiplied by the house Voltage readings provided by IotaWatt.


Don’t mind the duplicate in there. One was a debugging item I was using and just left it.

That’s fine, looks like you have a Power to kWh feed as process number 8, if you use that with the delta mode in the bar graph it should give the best results: https://guide.openenergymonitor.org/setup/daily-kwh/

Voltage multiplied by current yields Volt-Amps, (VA) i.e apparent power vice real power.
To get real power, you must take into account the power factor, as well. (V x I x PF)

If the load is resistive i.e. no reactive components, the Power factor will be 1
and Watts will be equal to VA.

Plus, if two different devices are being used, there’s no guarantee whatever that the two quantities are measured at the same instant - so there is another source of uncertainty.

Very true. Unfortunately I don’t believe the OpenEVSE reports the pf back, so I was just aiming for a general total energy consumption. (though I only pay rates based on real power) Unless of course the OpenEVSE total Wh report does include pf in it. If that’s the case, then I would consider seeing if I could parse out what the days energy usage was from it. I just couldn’t seem to find a way to get EmonCMS to do that.
