V3.80~14 virtual EV behaviour

Node-RED

Installed 14 without problems on my system. Wanted to try Virtuel energy meter with role EV charger, and wanted to try Virtual EV

Virtual Energy Meter with role EV charger - observations

  • filled with data using nodered
  • Example JSON witch I use to fill the virtual meter
  • {"/Ac/Power":0,"/Ac/L1/Power":0,"/Ac/L2/Power":0,"/Ac/L3/Power":0,"/Ac/L1/Voltage":232.2,"/Ac/L2/Voltage":232.2,"/Ac/L3/Voltage":232.8,"/Ac/L1/Current":0,"/Ac/L2/Current":0,"/Ac/L3/Current":0,"/Ac/Energy/Forward":11940.071}
  • Result is a visible EVCS widget on the homescreen, but when I look in devices on the console I see only actual power, and the total. Is this expected behaviour?
  • The position is showed on the widget screen as on AC-out. I switched it to AC-in with the correct path, but nothing changes in the widget.
  • I did a charge last night and is see the darn power in the widget graph, in all the rest it is not shown as EV charger use. Expected behavior? (edit, last night’s charge is visible in betavrm)

Virtual EV

  • filled with data using nodered
  • Example JSON witch I use to fill the virtual EV
  • {"/Soc":52,"/TargetSoc":65,"/ChargingState":0,"/Odometer":41050,"/RangeToGo":218,"/Position/Latitude":-removed-,"/Position/Longitude":-removed-,"/AtSite":0,"/LastEvContact":1775799530}
  • I don’t see the EV in the VRM homesreen, also not when I use beta VRM. Is this expected behaviour? EDIT 16april: Now I see a widget!
  • I can see the car as a device in the console - devices. It looks like it does not do anything else for now. Correct?

Thanks for now!

Watched again during a charge, this is the JSON going into the virtual energy meter node (role EVcharger)

{“/Ac/Power”:5962,“/Ac/L1/Power”:2000,“/Ac/L2/Power”:1965,“/Ac/L3/Power”:1996,“/Ac/L1/Voltage”:228.8,“/Ac/L2/Voltage”:227.8,“/Ac/L3/Voltage”:229.5,“/Ac/L1/Current”:8.77,“/Ac/L2/Current”:8.66,“/Ac/L3/Current”:8.73,“/Ac/Energy/Forward”:11941.174}

But only the actual power en total energy are recoded into the virtual energy meter with role EV charger. Am I doing something wrong? Or is this intentional/unfinished?

And while charging I also see for the virtual EV node that charge status is ignored, gives unknown in the device list on the console, but ‘2‘ is sent to it, so I expected ‘Charging‘

Hope it helps

Hallo

This is normal, i have a EM24 for metering my EVCS

you only see the power

Ok, so nothing weong from my side then. Is this something under development? I hope so :slight_smile:

For the Virtual EV, I now see my car as a widget on the VRM dashboard. Something changed and now this works. Cool :slight_smile:

Can you give an example of your data object feeding into the EV node?
It’s not appearing on the VRM for me

Edit: Got it! Apparently it’s mandatory to include the timestamp in unix format, missed that.

Yes it was in my first post, but I see you already found it :slight_smile:

Now we hope this data is going to do something with D-ESS. I hope very soon D-ESS knows how many kWh is needed for a charge, and at least plans this as expected use at the best moment, based on historical data. Then I can match my charger with the D-ESS planning. Fully automated will be better, but first things first..
