custom widget: send command to node

[elgarfo]

hi,

i have read the "widget - sensor custom buttons", "rgb controller", "custom widget" and "custom widget - dynamic images on dashboard" topics but did only get a hint on what to do.

what i have:
a custom widget with a nice, touch enabled color picker, which is working. which means:

• can be displayed on the dashboard
• and is usable
• and javascript events are fired (currently logs a rgb hex value to browser console)
• using: iro.js

what i want:

• send the selected rgb hex value to a node

i saw a mention to create a custom angular controller and plug that into Utilities > HTML additional headers > AngularJS custom controllers.
can anyone provide an example of a angularjs controller to put there?

i tried to use Utilities > Scripts like in the example "Custom widget" but the variables defined there do not seem to be accessible in the Templates. at least i was unable to use it to send a value to the node.

so... i am currently stuck.
is there any documentation (other than plowing through mycontrollers code) which describes how to add a custom widget which can send a value to a node generated in js? i know its possible to send a value using the Utilities > Scripts but this is rather static, as the script only runs during widget creation. which means it only runs on opening the dashboard and if i change the color-picker by touching/clicking it, i can not push the value to a node.

@elgarfo Yes, It is possible to add your custom controller in Utilities > HTML additional headers > AngularJS custom controllers. can you share your current work, I can extend from there?

[elgarfo]

@jkandasa, thanks for helping me out.

currently i have this as template:

<style type="text/css">
.wrap {
  color: #fff;
  background: #171F30;
  margin: 0 auto;
  display: flex;
  flex-direction: row;
  align-items: center;
  justify-content: center;
}
</style>
<div class="wrap">
  <div class="colorPicker"></div>
</div>
<script>
var colorPicker = new iro.ColorPicker(".colorPicker", {
  width: 320,
  height: 320,
  color: {r: 255, g: 0, b: 0},
  anticlockwise: true,
  borderWidth: 1,
  borderColor: "#fff",
});

colorPicker.on("color:change", function(color) {
  console.log("hex: " + color.hexString);
});
</script>

and this for the script:

var colorSensor = mcApi.uidTag().getByUid("hi-wz-rgb-1").getResource();
var uuid = mcApi.utils().getUUID();

i tried to copy the "Sensors" controller from github modify it to make for a "Sensors2" controller an pasted that into the "AngularJS custom controllers":

'use strict';

angular.module('adf.widget.myc-sen-vars2', [])
  .config(function(dashboardProvider){
    dashboardProvider
      .widget('mycSenVars2', {
        title: 'Sensors2',
        description: 'Monitor and change sensors state',
        templateUrl: 'controllers/adf-widgets/adf-myc-sen-vars/view.html?mcv=${mc.gui.version}',
        controller: 'mycSenVarsController2',
        controllerAs: 'mycSenVars2',
        config: {
          variableIds:[],
          showIcon: true,
          itemsPerRow:"2",
          refreshTime:30,
        },
        edit: {
          templateUrl: 'controllers/adf-widgets/adf-myc-sen-vars/edit.html?mcv=${mc.gui.version}',
          controller: 'mycSenVarsEditController2',
          controllerAs: 'mycSenVarsEdit2',
        }
      });
  })
  .controller('mycSenVarsController2', function($scope, $interval, config, mchelper, $filter, SensorsFactory, TypesFactory, CommonServices){
    var mycSenVars2 = this;

    mycSenVars2.showLoading = true;
    mycSenVars2.isSyncing = true;
    mycSenVars2.variables = {};
    $scope.tooltipEnabled = false;
    $scope.hideVariableName= !config.showIcon;
    $scope.cs = CommonServices;

    //HVAC heater options - HVAC flow state
    $scope.hvacOptionsFlowState = TypesFactory.getHvacOptionsFlowState();
    //HVAC heater options - HVAC flow mode
    $scope.hvacOptionsFlowMode = TypesFactory.getHvacOptionsFlowMode();
    //HVAC heater options - HVAC fan speed
    $scope.hvacOptionsFanSpeed = TypesFactory.getHvacOptionsFanSpeed();

    //Defined variable types list
    $scope.definedVariableTypes = CommonServices.getSensorVariablesKnownList();



  //update rgba color
  $scope.updateRgba = function(variable){
    variable.value = CommonServices.rgba2hex(variable.rgba);
    $scope.updateVariable(variable);
  };

    function loadVariables(){
      mycSenVars2.isSyncing = true;
      SensorsFactory.getVariables({'ids':config.variableIds}, function(response){
          mycSenVars2.variables = response;
          mycSenVars2.isSyncing = false;
          if(mycSenVars2.showLoading){
            mycSenVars2.showLoading = false;
          }
      });
    };

    function updateVariables(){
      if(mycSenVars2.isSyncing){
        return;
      }else if(config.variableIds.length > 0){
        loadVariables();
      }
    }

    //load variables initially
    loadVariables();
    //updateVariables();

    //Update Variable / Send Payload
    $scope.updateVariable = function(variable){
      SensorsFactory.updateVariable(variable, function(){
        //update Success
      },function(error){
        displayRestError.display(error);
      });
    };

    // refresh every second
    var promise = $interval(updateVariables, config.refreshTime*1000);

    // cancel interval on scope destroy
    $scope.$on('$destroy', function(){
      $interval.cancel(promise);
    });
  }).controller('mycSenVarsEditController2', function($scope, $interval, config, mchelper, $filter, TypesFactory, CommonServices){
    var mycSenVarsEdit2 = this;
    mycSenVarsEdit2.cs = CommonServices;
    mycSenVarsEdit2.variables = TypesFactory.getSensorVariables();
  });

but this does not show up at all in the dashboard.

that's why i am asking for a simple example for a custom angular controller as i am not too familiar with angular yet.

[jkandasa]

@elgarfo Thanks for the script. Looks like iro.js do not have angular support
For two way binding, we need angularJS support.

[elgarfo]

@jkandasa ok thats a little sad. but this will not stop me from trying

lets say i wanted to write a custom widget (lets also assume something simple like an html5 slider/range input)

template:

<input id="slider1" type="range" min="0" max="100" />
<script type="text/javascript">
  $('#slider1').on('change', function(e) {
    console.log('slider1 value: '  + $(this).val());
  });
</script>

script:

var stepperMotor = mcApi.uidTag().getByUid("hi-wz-blinds-1").getResource();
var uuid = mcApi.utils().getUUID();

as far as i can tell, this is a pretty basic example which does not rely on incompatible external libs. what do i need to add to which section to make this a widget with two-way binding?

all i am looking for is an example for a custom 2 way widget.

[jkandasa]

@elgarfo I do not know how to do with HTML 5. however I made a two-way widget with the angular slider.

Steps:

• create HTML template with sensor variable id
• create dummy javascript to supply buildings
• add custom css and js files.
• add custom controller
• add dependency module in angular (workaround, I do not find a way to include new modules into the controller creation)

HTML template:

<div ng-controller="myCustomWidgetController" ng-init="sVariable.id=${sId};loadVariable();">
  <rzslider rz-slider-model="sVariable.value" rz-slider-options="slider.options"></rzslider>
</div>

Dummy JavaScript:

// dummy script

CSS and JS file:

https://cdnjs.cloudflare.com/ajax/libs/angularjs-slider/6.6.0/rzslider.min.css
https://cdnjs.cloudflare.com/ajax/libs/angularjs-slider/6.6.0/rzslider.min.js

Custom controller:

myControllerModule.controller('myCustomWidgetController', function($scope, SensorsFactory){
    $scope.sVariable = {
      id: null,
      value:null
    };
  
    $scope.loadVariable = function(){
      SensorsFactory.getVariable({id:$scope.sVariable.id}, function(response){
        if(response.value != undefined){
          $scope.sVariable.value = parseInt(response.value);
        }
      });
    }

    $scope.slider = {
      options: {
        floor: 0,
        ceil: 100,
        step: 1,
        minLimit: 0,
        maxLimit: 90,
        onEnd: function() {
            $scope.sendPayload($scope.sVariable);
        },
      }
  };

    // send payload
    $scope.sendPayload = function(sVariable){
      SensorsFactory.updateVariable(sVariable, function(){
        //update Success
      },function(error){
        displayRestError.display(error);
      });
    };
  });

Workaround, add a module on the app level

File: mycontroller/www/app.js

rzModule

Widget in dashboard

[elgarfo]

@jkandasa your support is outstanding
your example works good and i can use it to build a dashboard to my needs. thank you very very much.

the reason it took me so long to respond is, that i needed to trace a startup error on my end:
[$injector:nomod] Module 'rzModule' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

symptoms:

• dashboard not loading correctly ({{ variable }} everywhere, nothing works)
• angular throwing error about undefined module
• testing with dev-console on firefox angular.module('rzModule'); yielded no error.
• rzslider.js was actually loaded

cause:

• firefox does not support <link rel="import">
• the polyfill i pushed to github fb3d0d96 is working but:
• too late.

so the polyfill for the import-feature is working, as i am able to load the rzModule after the dashboard html loaded completely and angular tried to load.
but it is not working fast enough.

i am currently trying to find a way to either delay angular startup until all imports are handled or to find a better way to include the /_configurations/additional-headers.html

current workaround: put <script src="https://cdnjs.cloudflare.com/ajax/libs/angularjs-slider/6.6.1/rzslider.js"></script> directly into index.html for firefox

EDIT:
html imports are also deprecated in chrome since v70 and will be removed with v73 which is only two versions from now (v71 as of this writing). see: chrome platform status

[jkandasa]

@elgarfo If we change anything in our current implementation, can fix the issue in both firefox and chrome? Any idea?

[jkandasa]

@elgarfo Thank you for the PR https://github.com/mycontroller-org/mycontroller/pull/486

[wanvo]

How can I download the latest SNAPSHOT with this PR?
Is this it? Https: //travis-ci.org/mycontroller-org/mycontroller/builds/472109919

[jkandasa]

@wanvo Compiled and uploaded in SNAPSHOT location.

[wanvo]

@jkandasa Thanx!
I checked this widget in Chrome and Firefox, it works great.

[RMF69]

I'm just testing out various examples to understand how things work, I'm getting

Failed at: ${sId}  [in template "unknown" at line 1, column 69]

which I assume is from the first line of the html template, its not finding the angularjs custom controller ? I did modify app.js.

I'm pretty sure I've done all of the above to get the slider to appear on dashboard, but I must of missed something. I pasted the angularjs custom controller into the text field in HTML additional headers.

Any help thanks

[RMF69]

@RMF69 To myself... the script binding id mistyped {sId:2}... got the camel case wrong. Slider is now visible but I get 400 error... as I don't have the variable set up correctly which will get updated ? I've created a global variable "sVariable" but I don't think this is right. How do I get the value out of the slider when its value changes ?

[RMF69]

@RMF69 Ok looking through code, I understand that its updating a sensor.variabel and that this id is passed in via the script binding {sId:31}... 31 is the id of a sensor S_LIGHT_LEVEL![alt text](
I still get 400 bad requests... and

ERROR [Acme.Utils.ThreadPool(0)-PooledThread: Acme.Serve.Serve$ServeConnection@1415568e] [org.mycontroller.standalone.api.jaxrs.exception.mappers.ApplicationExceptionMapper:42] ApplicationException,
org.jboss.resteasy.spi.ApplicationException: java.lang.NullPointerException

I'd love to understand what I've done wrong:)

[jkandasa]

@RMF69 Can you report your MyController version? and if you modified the script please report your script.

[RMF69]

@jkandasa

Thanks, I've got the latest, Version 1.5.0. And I've not changed anything, just the script binding {sId:31} where 31 is the id of a light dimmer virtual sensor... see picture. I took the ID from the url of that page in the picture below.

[jkandasa]

@RMF69 Click on the Edit icon on the Level variable and use the id from the URL.

in version 1.5, you no need to hardcode rzModule on mycontroller/www/app.js. We have an option on UI to update angular modules.

[RMF69]

@jkandasa Thanks for confirming that in 1.5, the hardcoding of rzModule in mycontroller/www/app.js isn't required. However if I remove rzModule then the slider widget isn't displayed.

Still I can't get the example to work...I've got the id from the place you mention, mine is still 31... I've also noticed that the intial value of the sensor->variable isn't populated. I created simple script to update the value

var myImports = new JavaImporter(java.lang, java.util, org.mycontroller.standalone.utils.McUtils);

with(myImports) {
    dimSensor = mcApi.uidTag().getByUid("dimSensor").getResource();
    var v = dimSensor.value; //value2/3 etc
    dimSensor.setValue(parseInt(v) + 1);
    mcApi.sensor().sendPayload(dimSensor);
}

I insert the following code into "AngularJs custom controllers"

myControllerModule.controller('myCustomWidgetController', function($scope, SensorsFactory){
    $scope.sVariable = {
      id: null,
      value:null
    };
  
    $scope.loadVariable = function(){
      SensorsFactory.getVariable({id:$scope.sVariable.id}, function(response){
        if(response.value != undefined){
          $scope.sVariable.value = parseInt(response.value);
        } 
      });
    }

    $scope.slider = {
      options: {
        floor: 0,
        ceil: 100,
        step: 1,
        minLimit: 0,
        maxLimit: 90,
        onEnd: function() {
            $scope.sendPayload($scope.sVariable);
        },
      }
  };

    // send payload
    $scope.sendPayload = function(sVariable){
      SensorsFactory.updateVariable(sVariable, function(){
        //update Success
      },function(error){
        displayRestError.display(error);
      });
    };
  });

Which is just the original example above, no changes... it seems to me that the pointer/reference to the variable I want to have connected to the slider is correct or working, both when the value is initialized on the loadVariable and when updated. But I just can't see what I've done wrong.

[jkandasa]

@RMF69 Do you see any error on the browser console and/or in MyController log file?
