As with web development, ids are meant to uniquely determine an element. You shouldn’t use the same id for different elements. This is true even when those elements are inside different HTML templates, if both templates may be active at some point during the runtime of the app
You cannot change a template that is not active. The uiViewSet might be something worth looking at, depending on what you’re trying to achieve

You can fetch data from any device which supports being in peripheral mode – even a laptop. In your case, you would need to write an application for your phone which communicates with the watch using Bluetooth Low Energy.

Hi @harry08 .

That is right, you can only get precise current time or the day of the week. The rest needs to be calculated manually

Is it possible to get the Suunto Plus Guide a user has selected for the current workout? The goal would to the show a graphic representation (for example bar chart) to show all intervals of the workout and vertical ruler showing the current point in the workout.

Thanks for the hint! This worked for my case.

Awesome, works fine for me. Worth buying new watches then!

Connect watch to macbook - VSCode

Should this work?

I have a older (rather old macbook running monterey. I couldn’t connect the watch to deploy my app on it.
Maybe it failed cause the watch hasn’t been properly disconnected from the phone see my other thread over here:

Does the watches JS-runtime support WASM by any chance?

Hello, can anyone help, I am trying to display Graph for HearthRate.

I am using this code for displaying graph, it is taken from one of examples just modified input path for current hearth rate:

<graph style="position:absolute;
              left:0px; top:0px; width:100%; height:100%;
              box-sizing: border-box;
              padding-right:90px; padding-top:60px; padding-bottom:60px;
              font-size:21px;"
       valueFormat="HeartRate_Fourdigits"
       type="line"
       grid="three lines"
       inputType="subscribe"
       input="/Activity/Move/-1/HeartRate/Current"
       min="0.6666666667"
       max="3"
       slack="0.1"
/>

and it works fine in simulator and I see this:

but when I upload app to watch (Suunto 5 or Race 2), than there is no graph line for Heart Rate:

@Tomas5 thanks Tomas I tried your method, it just return 0 to me, but i find out if ur ui is big enough it will able to scroll down,dont have to do anything.

Hello,

What I want to do is quite simple but I do lack experience with JS, and it has been a long time since I developed in HTML.

I would appreciate your help :). I want to override down button press to make a lap type 24, but only if activity is ongoing. If it is paused I want the default behavior (stop activity).

In my html:

<userInput>
      <pushButton name="down" onClick="$.put('/Zapp/{zapp_index}/Event', 123, null, 'int32');" />
</userInput>

In my js:

function onEvent(input, output, eventId) {
  if (eventId == 123) {
    // Down button was pressed
    $.put('Activity/Trigger', 24);
  }
}

I was thinking of conditioning the HTML onClick but do not really know how to access necessary variables, etc. I have tried a few things but I am lost.

Unpaired8373

@Thibault-B. There is an example in the examples collection. Essentially have a global variable that is set in the start-handler and unset in the stop-handler and then handle the condition in you event

Thibault B.

@Unpaired8373 Not sure to get what you mean.

function onEvent(input, output, eventId) {
  if (eventId == 123 && output.isPaused == 0) {
    // Down button was pressed
    $.put('Activity/Trigger', 24);
  }
}

It is not triggering the lap but it is not doing anything else and I wanted to default to initial behavior (so I didn’t want an explicit call to stop, which seems anyway not available?).

Thibault B.

I think the issue is that I override the onClick action, so I should keep it empty if in pause. But I do not know how to do it.

I’m working on an app for speedsurfers :

I struggle a little bit with the Alpha category.
According to the gps-speedsurfing rules the Alpha category is the speed over 500m, including a gybe (180 degree turn), and the start and endpoint needs to be within 50m of eachother.

To determine if there was a gybe, I thought about recording the direction for each second, but I noticed that isn’t available as parameter.
So the only other option I see is derive the direction from the coordinates, but that includes some calculations.

Any other ideas?

Is it expected that even an example app crashes the watch with a Syntax Error ?

After having my own app crash - and almost brick the watch or at least having it perform a fault recovery for a couple of minutes - I thought I reduce the app to a bare minimum and work from there but even that crashes the watch. I then copied the Dynamic Icons example but still get the crash log below:

Hi @Unpaired8373 ,

Wasm is not available!

Is it expected that even an example app crashes the watch with a Syntax Error ? … I then copied the Dynamic Icons example but still get the crash log below

That is not expected behaviour I just now checked the Dynamic Icons example on both a Race 1 and a 9 Peak Pro. Neither crashed during an exercise. Best advice that comes to mind is to first make sure the watch is running the latest firmware.

Running JS inside an HTML template can be a bit finicky and seems to have the highest potential for crashes at present.

We do not presently have a way to capture scrolling events, but as you found…

i find out if ur ui is big enough it will able to scroll down,dont have to do anything.

… the watch will automatically attempt to scroll elements with the crown
