2 weeks back I asked this question. "Or do I make a mistake?"Kedi wrote: ↑Tuesday 09 July 2024 11:08I placed 2 pictures. The 3 Watts in the Solar circle should be negative, see the widget.
The panels are consuming power instead of delivering power.
I am measuring power with a Shelly EM, and that device can measure in 2 directions positive and negative.
And yes a converter stays on the net and consumes power when there is no sun.
The house get some power and the converter get some power.
So the total of those 2 comes from the net.
Or do I make a mistake?
I suppose you do not make a mistake but the dashboard probably does not take into account negative values from a solar panel set. Inverters do not show these negative values. You measure it yourself so you see it. Perhaps it is an easy fix in the web part of the energy dashboard and you can play with it yourself and make an easy update and PR. Else it needs a C++ change.Kedi wrote: ↑Tuesday 23 July 2024 7:252 weeks back I asked this question. "Or do I make a mistake?"Kedi wrote: ↑Tuesday 09 July 2024 11:08I placed 2 pictures.

I really would appreciate an answer.
Code: Select all
$scope.fActualSolar = Math.round(Math.abs(parseFloat(item["Usage"].replace(' Watt',''))));Code: Select all
$scope.fActualSolar = Math.round(parseFloat(item["Usage"].replace(' Watt','')));I checked and it is only a small visual solution. Indeed the value on the Dashboard is now negative.waltervl wrote: ↑Tuesday 23 July 2024 9:14 I suppose you do not make a mistake but the dashboard probably does not take into account negative values from a solar panel set.

Edit: looking at the code in https://github.com/domoticz/domoticz/bl ... troller.js line 405 the Math.abs part should be removed as that makes it a positive value.should perhaps beCode: Select all
$scope.fActualSolar = Math.round(Math.abs(parseFloat(item["Usage"].replace(' Watt',''))));Code: Select all
$scope.fActualSolar = Math.round(parseFloat(item["Usage"].replace(' Watt','')));
Then you need to play a little bit more with the javascript EnergyDashboardController.js, perhaps somewhere else it is calculated wrongly now. If I could find the first change I am sure you can find and modify the rest of it.Kedi wrote: ↑Friday 26 July 2024 6:50I checked and it is only a small visual solution.

But the dotted line did not change and more important nothing changed in the calculation of prices in the database etc....
So Prices and kWh values are not consistant with each other.
You can try to integrate it via iframe. But of course you have to open your lokal URL to the public internet first. Something like this:Toulon7559 wrote: ↑Sunday 04 August 2024 7:57 Nice Dashboard.
