Add single price per day PLUS price per Kwh

Hello Jas

Is is possible to create a tariff which has a fixed price per day tariff PLUS price per Kwh used?

Yes, it is possible, but not easy)

The Dashboard is very flexible and you can compose complex functions in JavaScript syntax in the widget settings in the Arithmetic operation with f(x)

An example for your task:
- make a table widget on the Dashboard
- select data display interval - MONTH. The data will be correct only for MONTH interval for this example.
- add consumption data [TW]
- add another bookmark with Arithmetic operation f(x)

var costDay = 5;
var costWatt = 0.0015;
var md = new Date(d.TIME).setMonth(new Date(d.TIME).getMonth()+1);
if (md > new Date()) {
new Date().getDate()*costDay + d.TW*costWatt;
} else {
new Date(+md-1).getDate()*costDay + d.TW*costWatt;
}

Where:

costDay -  a fixed price per day

costWatt -  price per Watt (= price per kWh / 1000)

Hi, thanks for this.  I'm still trying to implement this solution.  

Why do I not have TW as an option? 

Also - what do you mean by "- add another bookmark with Arithmetic operation f(x)" - I don't seem to have the ability add TABS across the top of my widget - is that what you mean?

[TW] - for 3-lines D103 devices only.

For 1-line device D101 it is just [W]

To add new tab

Thanks again for your help....

I now have

NaN error....  

This is my formula

Any ideas?

[TW] - for 3-lines D103 devices only.

For 1-line device D101 it is just [W]

So, in the formulas use d.W instead d.TW
