Wrong units used for EVCC power numbers?

[MortuuS]

Description

Hi,

First of all thanks for this great dashboard!

When setting up my EVCC widget it seems that the wrong units are used for the data displayed. The widget shows the various power numbers of my home and charger. Which are displayed in Watt (W) in EVCC itself. However the Hompage widget shows the Watt hour (Wh) unit, but that is a unit for energy not power.

I tried to fix it with a Javascript solution.

var y = document.getElementsByClassName("font-thin text-sm");
var i;
for (i = 0; i < y.length; i++) {
  y[i].textContent = y[i].textContent.replace(" Wh", " W");

This works perfectly, until the page reloads the EVCC numbers by itself. Then the old units are used again. :(

Would it be possible to fix this issue? :)

I dont have one of these things, so according to the widget author these were the correct units: #1473 (comment)

If that is not the case it would be good to be 100% certain of this. The API docs aren't very helpful https://docs.evcc.io/docs/integrations/rest-api#state

But agree, "power" in the names makes me think they're just watts

Comparing the units between EVCC itself and the widget, I'm pretty sure it should be Watt.
Thanks for your help. ;)

Looks like all of them kW then?

[MortuuS]

Yes, EVCC shows them as kW.
I'm not sure if the comma in the number shown on the widget (3,188) designates a decimal number or is just a seperator for a number larger than 1000) due to the differences between Euro and US presentation of numbers.

Officially in the EU a number with a comma is a decimal so yes then it should be kW. If it is just a separator for legibility (as is done in the US I think?) it should be W.

Thanks #4396
