Custom Output to display

[Darvos]

Guys, I need to create a Custom Widget wich can work with a few inputs and variables I create!

So... I already made the logic work, created the tags and etc.. but I'm stuck at the template part!

How can I make the connection btw the script and the template and what the heck is script binding?

Here is the code I came up with :

var myImports = new JavaImporter(java.io, java.lang, java.util); 
Amp1= mcApi.variable().get("Amp1");
Consumo1 = mcApi.variable().get("Consumo1");
var sensorVariable = mcApi.uidTag().getByUid("VoltRaw1");
var dispItems = [];
with(myImports)
 {
Consumo1 = Amp1.value * sensorVariable.sensorVariable.value;
}

@Darvos Script bindings are input to your script. You can read those input as a variable. Example: {"threshold": 85.4, "variable_xyz": 44, "my_text": "hello"}

I do not understand what you want to do? Could you please elaborate a bit more on this?

Sure, I want to multiply an input by a variable , put the result in a variable and show it at my dashboard !

Example : I'm reading a light sensor, I wanna have both the raw value and the valia of the light multiplied by certain number in my dash board!

So I create a "sensor viewer " and a "custom viewer " right?

Well, for the custom viewer I need a script to do the job for me... taking both utags and variables and doing a simple multiplication , then show me the valeu ... right?

Well I need help finishing the script because, I can make the simple code but can't make it show the valeu at the "custom viewer " . I guess I'm missing both the template and the script binding

In other words , how can I display a variable, not a input or a tag, just a variable

@jkandasa I forgot the reply you didn't I?

Sorry, but I'm still hoping you can help me with this.

Thank you very much

@Darvos You have to do all your calculations on your script and create an HTML template to display the value on the dashboard. Example: http://forum.mycontroller.org/topic/144/how-to-show-several-sensor-readings-in-a-single-widget/4

@jkandasa Thaaaats IIIITTT ^^

Thank you thank you thanks aloooot jkandasa, you beatiful man!!

I was expecting this for days, and I'm really excited with the outcome of this project

@Darvos

JavaScript

var myImports = new JavaImporter(java.io, java.lang, java.util); 
with(myImports) {
  var amp1 = mcApi.variable().get("Amp1");
  var volt = mcApi.uidTag().getByUid("VoltRaw1").getResource();
  // custom value
  var finalData = amp1.value * volt.value;
}

HTML template

<div>My custom value: ${finalData}</div>
<div>Raw values:[Amp1:${amp1.value}, volt:${volt.value}]</div>

Note: Use the latest version of MyController from here

@jkandasa J, my saivior!! the project is working just fine, i only have one question to make!! plz save me!!

i've been trying to acumulate values (anyvar += anyvar) without sucess...

I tried loops, timers, no sucess...

I need to sum all the values I gather since the first reading.. any tip?

[Darvos]

@jkandasa Gosh, so.. I was doing some research over the forum... and I found this http://forum.mycontroller.org/topic/139/hour-meter wich I've been trying to use with no sucess...

let me put some good info here!

I've made those simple custom widgets, here is the script for them

var myImports = new JavaImporter(java.io, java.lang, java.util); 
var Custo = 0;
with(myImports) {
  var amp1 = mcApi.uidTag().getByUid("AmpRaw1").getResource()
  var volt = mcApi.uidTag().getByUid("VoltRaw1").getResource();
  var taxa = mcApi.variable().get("Taxa"); 
  var Custo_aux = mcApi.variable().get("CustoT"); 

  // custom value
  var finalData = (amp1.value * volt.value)/ 1000;
  Custo_aux.value = finalData * taxa.value;
}

I just need a way to acumulate(a.k.a SUM) the values os the last line like Custo_aux.value += the rest...

I've been trying to use the .save() without success too..

Plz master J, help me out!!

@Darvos By default, Repository and SensorVariable values will be stored as String You need to convert it to Integer, Float or as you like.

var myImports = new JavaImporter(java.io, java.lang, java.util); 
with(myImports) {
  var amp1 = mcApi.uidTag().getByUid("AmpRaw1").getResource()
  var volt = mcApi.uidTag().getByUid("VoltRaw1").getResource();
  var taxa = mcApi.variable().get("Taxa"); 
  var Custo_aux = mcApi.variable().get("CustoT"); 

  // custom value
  var finalData = (parseFloat(amp1.value) * parseFloat(volt.value))/ 1000;
  var currentCusto = finalData * parseFloat(taxa.value);
  Custo_aux.value = parseFloat(Custo_aux.value) + currentCusto; //SUM with previous values
  Custo_aux.save(); //store it on repository
}

Note: Repository variables Taxa, CustoT should be created with default values. before to execute this script at first time.
