How to create slider in dashboard template

Dashboard
1

Any idea what I'm doing wrong here?

I am trying to create a lighting automation, by storing values for individual light fixings (as well as scenes / presets for multiple fixtures) in an object in context memory. The object looks like this:

context
context.png975×722 41.3 KB

I have created a dashboard template that enumerates the light fixtures shown above (ceiling, wall, bedside, etc.) and it creates a label and slider for each fixture (and shows its value underneath, for testing)

<div ng-repeat="(key, value) in msg.payload">
    <p>{{value.name}}</p>
    <md-slider min="0" max="100" step="5" ng-model="value.state" ng-change="send(msg)"></md-slider>
{{value.state}}
</div>

This creates the slider fine, and the testing value shows 50, which is the correct value set in context memory. However the initial slider value is set to zero, despite {{value.state}} being 50. (Sorry, my screenshot above shows 80, just ignore that.)

If I change the ng-model parameter to add curly brackets {{ }} it stops the slider moving (and doesn't set the initial value to correct amount).

  1. How do I fix this so the slider reflects the correct value in memory, when data is sent to the dashboard template? i.e. at startup

  2. Every time I update the slider, because I'm sending the whole msg object, it will store back ALL of the light fixtures and their metadata. Obviously I don't want this. I just want to send back the actual value that was changed. This would require the template node to send out TWO pieces of data: the name or ID of the fitting, and its value. I have fiddled with ng-change, for example ng-change="send(value.name, value.state)" but that just sends the first item out (the name), not both. How can I do this?

Any other suggestions for how I'm doing this (i.e. "you're doing it all wrong!") will be received with great interest!

Cheers, and happy holidays :slight_smile:

Resolved, in case anyone searches this later:

<div ng-repeat="(key, value) in msg.fixturesettings">
    <div style="display:inline;width:20%">{{value.label}}</div>
    <div style="float:right;width:80%"><md-slider min="0" max="100" step="{{value.resolution}}" ng-model="value.setting.brightness" ng-change="send({action: 'bri', topic: key, brightness: value.setting.brightness})"></md-slider></div>

Thanks for sharing
I'm doing something very similar been playing around with layout and styling of slider

<div>
    <div>LC3 Under Cabinet Lights</div>
    <div class="sliderGrid">
        <div><md-slider min="0" max="100" step="10" ng-model="msg.payload.v1" ng-change="send({topic: 'v1', v: msg.payload.v1})" class="lightSlider"></md-slider></div>
        <div ng-bind-html="msg.payload.v1" class="dimValue"></div>
    </div>
</div>
<div>
    <div>LC4 Table lights</div>
    <div class="sliderGrid">
        <div><md-slider min="0" max="100" step="10" ng-model="msg.payload.v2" ng-change="send({topic: 'v2', v: msg.payload.v2})"  class="lightSlider"></md-slider></div>
        <div ng-bind-html="msg.payload.v2" class="dimValue"></div>
    </div>
</div>
<style>
.sliderGrid{
    display: grid;
    grid-template-columns: 85% 25px;
    margin-left: 25px;
}

.lightSlider {
    float:right;
    width: 100%   
}
.lightSlider .md-thumb:after, .lightSlider .md-track{
    background-color: #FA9900 !important;
    border-color: #FA9900 !important;
}
.lightSlider .md-focus-thumb, .lightSlider .md-focus-ring{
    background-color: #FA9900;
}
.dimValue {
  clear: right; 
  margin: 10px; 0 0 7px;  
}

</style>

Thanks, I'll try out your styling

I've done a bit more since then

I you use md-discrete it should only send once you've finished dragging but you need

.md-track-ticks canvas { display: none; }

This will fill the slider as it's dragged

.dimSlider .md-thumb:after, .dimSlider .md-track-fill{
    background-color: #F9BE1F !important;
    border-color: #F9BE1F !important;
}

@iiLaw Lawrence - I tried your code without this bit and two sliders do appear, but I can not move them. All I get in the debug is a payload of "undefined"

I tried in Safari, Chrome and FireFox and all experience the same thing.

This is running on a Mac
macOS 10.14.6
Node-RED v1.0.2
Node.js v12.13.0
Dashboard v2.19.1

ok I've had that and can't remember how to fix

I need to de-angular some of my template code below to recreate the above once I have will post but if your angular is your thing

 <div ng-repeat="controls in msg.payload.controlS | filter:{lbl: '!!'}">
        <div>{{controls.lbl}}</div>
        <div class="{{controls.type}}Grid">
     
            <div ng-If="controls.type == 'dim' "><md-slider id="{{msg.gpId}}C{{$index+1}}" min="0" max="100" step="10" ng-model="controls.v" ng-change="send(action({gpId: msg.gpId, id: $index+1, v: controls.v}))"  md-discrete class="dimSlider"></md-slider></div>
            <div ng-If="controls.type == 'dim' "  id="{{msg.gpId}}C{{$index+1}}v" ng-bind-html="controls.v" class="value"></div>
    
        </div>
    </div>

Actually I'm not using it for anything. I saw the thread and decided to try your code and when it didn't work I thought it best to report the issue :grin:

@zenofmud Paul thanks test on chrome & FF on win10
And chrome on iOS

}
.dimSlider {
    float:left;
    width: 90%

.dimSlider .md-thumb:after, .dimSlider .md-track-fill{
    background-color: #F9BE1F !important;
    border-color: #F9BE1F !important;
}
.value {
  clear: right; 
  margin: 10px; 0 0 7px;

It's still not working for me in iOS 13.2.2 or on my Mac in Safari, Chrome of FireFox. The top slider doesn't work at all and the bottom slider changes to a teardrop
51 AM
but slides back to 0 as soon as it is released.
12 AM

Ok I've testes on iOS 13.2.3. on Safari & Chrome works. Worked on 13.2.2 as well.
Not sure how I bottom this one out as I don't have a mac.

LC2 example is an example of output: only on release this same behavior as Dashboard slider. When you move focus away it should revert to a ring have to say the UX is bit odd, but I need send on release (e.d slide end).

Top sliders standard Dashboard sliders first continuous/second on release.
Bottom sliders my code.

Hi, Sorry to knock on an old door but this does not work at all for me on chromium from a ui_template (assuming the code came from one because the import of code does not work for me either).

I have been struggling with ui_template ng-slider for days now and have just raised a new topic:
https://discourse.nodered.org/t/ui-template-md-slider-help/37328/2

I get:

Old topic, but I have got my sliders to work within the UI template node.

I have some Shelly RGBW2 led controllers which I control using NodeRED. I have created a UI which controls the different RGB and White channels. So I treat the RGB as mixed and the White channel is a separate light source. I stole the UI of the iOS color picker. It looks nice and works as expected in the Safari (MacOS) browser.

My NodeRED implementation:

Unfortunately none of the above solutions work in my environment. MacOS 10.13 and iOS 11.x
The sliders cannot be moved, the only thing "sliding" is the dasboard screen if you have more than one..

Also the standard slider provided with the latest NR-dashboard works only on MacOS but not on any iOS version. Why is this GUI element so sensitive to the configuration?

@haegar33, I run almost the same setup.

On the server side I have a Pi 3 running Raspbian and node-red. A node-red gives me:

I have multiple client devices which use Safari, Chrome, Firefox (macOS 10.13, 11.2, iOS 12, 14.4) which all handle the webcode just fine.
