Emonsd Dashboard reporting error

Ryan_S · 14 January 2020 00:51

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?

TrystanLea · 15 January 2020 17:56

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

Ryan_S · 15 January 2020 18:16

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.

Ryan_S · 16 January 2020 01:16

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

TrystanLea · 16 January 2020 10:13

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?

Ryan_S · 16 January 2020 21:22

Figure a picture of the settings works.

TrystanLea · 18 January 2020 18:08

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: Calculating Daily kWh - Guide | OpenEnergyMonitor

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.

Ryan_S · 19 January 2020 14:06

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.

TrystanLea · 19 January 2020 21:11

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: Calculating Daily kWh - Guide | OpenEnergyMonitor

Bill.Thomson · 20 January 2020 01:37

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.

Robert.Wall · 20 January 2020 11:12

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.

Ryan_S · 21 January 2020 18:13

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.
