Struggle with custom getStatus function – never called

[mlinzner2]

I'm working on an energy dashboard and would like to adjust price per m3 / price per kWh based on dates. If I understand correctly, this is what getStatus in the custom\.js is made for.

Bare minimum config file I have right now:

Code: Select all

var config = {};
config["domoticz_ip"] = "[xxxxxx]";

blocks["costs"] = {
  title: "costs",
  devices: [97, 101],
  graph: ["line", "bar", "bar", "bar"],
  stacked: true,
  tooltiptotal: false,
  custom: {
    "last week": {
      range: "month",
      filter: "1 weeks",
      data: {
        total:
          "(d\.v_101*3\.33211)+(d\.v2_97*0\.75636)-(d\.r2_97*0\.109)+(d\.v_97*0\.82933)-(d\.r1_97*0\.109)",

        electricity_night: "(d\.v_97*0\.82933)-(d\.r1_97*0\.109)",
        electricity_day: "(d\.v2_97*0\.75636)-(d\.r2_97*0\.109)",
        gas: "d\.v_101*3\.33211",      
        },
    },
  },
};

columns[2] = {};
columns[2]["blocks"] = ["costs"];

var screens = {};
screens[1] = {};
screens[1]["background"] = "xxx";
screens[1]["columns"] = [2];

The hardcoded Kilowatt/Cubicmeter prices (3\.33211, …) I would like to adjust based on the date information available in d\.d_101 or d\.d_97.

Given the above configuration, I assumed that I can add getStatus_costs to my custom\.js and it should be called. So my file looks like this:

Code: Select all

function getStatus_costs(block) {
  console\.log("GET_STATUS_COSTS");
}

But the function is not called at all.

If I add afterGetDevices(), getExtendedBlockTypes() or deviceHook() to the same file, they get called, but I think they are not useful to what I want to achieve.


I'm currently running Domoticz Version 2022\.2 and Dashticz Version: 3\.10\.01.

What else could I do to debug this issue? Or is there any other way to achieve my required outcome? Any help is appreciated!

Please ignore the escaped dots, how on earth can I get around the external URL detection?

The getStatus function only gets called for Domoticz device blocks (switches, sensors etc.), not for graphs.

However, the data for a custom graph are calculated by the javascript function 'eval' meaning you can call any function.

For instance:

Code: Select all

total:
          "(d.v_101*getValue1())+(d.v2_97*getValue2())-(d.r2_97*getValue3())+(d.v_97*getValue4())-(d.r1_97*getValue5())",

and then just define the getValuex() functions in custom.js.

Alternative:
create a custom sensor in Domoticz, one for each value.
Then you can include the graph data of these sensors in your graph as well.

and then just define the getValuex() functions in custom\.js.

Amazing that would solve it! One last thing: What is the best way to access the dates inside the custom functions? The dates are available in d\.d_101 and d\.d_97 as Strings (eg "2023-01-05"). I tried to pass the date string into the function like so

Code: Select all

getValue1(d\.d_101)

That results in undefined values.
I also tried to pass the entire data object d to the function, this adds a bunch of values but not the date (possibly all values that can be parsed as float?).

Code: Select all

{"c1_97":73\.09,"c2_97":2\.704,"c3_97":110\.813,"c4_97":3\.276,"r1_97":0,"r2_97":0\.054,"v_97":2\.164,"v2_97":11\.358,"v_101":4\.64}

You would like to pass the date of the sample to the getValuex function?

ok, now we enter the trick area

You can add y.d as function parameter, like

Code: Select all

getValue1(y.d)

y.d is a javascript moment.js object. See https://momentjs.com/

Amazing, works like a charm! The fact that it is a momentjs object also makes the date comparisons easier to deal with
