        Sorry Richard, I'm not seeing anything sticking out here. The only thoughts I have is echoing out {{output}} inbetween both of the ng-if divs. Seeing how you're having two appear in one area makes me wonder if there's some sort of overlap or something stupid. Your values are definitely numeric.
        The next best idea Ive got is checking your console after doing a page load to see if any angular errors crop up..
        Otherwise I'm gonna have to call on Jared or Phil to help here. Sorry I cannot be of any further assistance. Either that or I'm just simply half asleep and it's staring me in the face!

          That's cool - I'm kinda glad it wasn't something glaringly obvious, and I appreciate your help!!

          Getting a couple of errors, but I'm not sure they are related:

            @richard-mortimer Hi

            I don't think you need to user parseInt etc as javascript will evaluate it as a number when there is a comparator.

            I tested this out with this code and got the desirable outcome

            <div class="ma-designer-root" id="ad15c8a3-1798-45ab-9771-535bb550b828" style="width: 1366px; height: 768px; position: relative;" ng-init="points=[
                {xid:'DP_3414e074-39ae-4179-b3e7-0775e7cabc54'},
                {xid:'DP_a7485f76-5c52-4c42-b49a-f17b3276a2f8'}]">
                
                
            <span ng-repeat="point in points">
                
                <ma-get-point-value point-xid="{{ point.xid }}" point="output"></ma-get-point-value>
                <div ng-if="output.value > 999">{{ (output.value / 1000) }}kW</div>
                <div ng-if="output.value < 1000">{{ (output.value)}}W</div>
            </div>
            

            If you look at your screen shot where the 'error" happens , 1.4kW is from the previous ng-repeat itteration.
            We can't see the rest of your code but by the looks of it, you have a table with nested repeats. I think you should refactor your code using ng-repeat-start and ng-repeat-end for all you nested repeats just to make sure the browser does not get confused.

            Edit:
            Another way to skin this cat would be to use a ternary expression.

            <div class="ma-designer-root" id="ad15c8a3-1798-45ab-9771-535bb550b828" style="width: 1366px; height: 768px; position: relative;" ng-init="points=[
                {xid:'DP_3414e074-39ae-4179-b3e7-0775e7cabc54'},
                {xid:'DP_a7485f76-5c52-4c42-b49a-f17b3276a2f8'}]">
                
                
            <span ng-repeat="point in points">
                <ma-get-point-value point-xid="{{ point.xid }}" point="output"></ma-get-point-value>
                <div>{{output.value >1000? output.value/1000:output.value}}{{output.value >1000?'kW':'W'}}</div>
            </div>

              @richard-mortimer I'm taking a guess at what is happening, but I'm pretty confident that this will fix it -

              <span ng-repeat="point in points[site.name] track by point.xid"><!-- Load -->
                  <ma-get-point-value point="point"></ma-get-point-value>
                  <div ng-if="point.value > 1000">{{ (point.value / 1000) | number:1 }}kW</div>
                  <div ng-if="point.value <= 1000">{{ point.value | number:0 }}W</div>
              </span><!-- end Load -->
              

              Two things -

              • Use track by in your ng-repeat expression so that Angular can correlate which points correspond to each span element when the points change.
              • Just pass the point to the <ma-get-point-value> component instead of retrieving it by XID again

                Thanks for that - I've made the changes and will keep an eye on it; unfortunately it only seems to happen at random times which makes it one of those "fun" bugs to iron out ... but I'm pretty confident that if you're pretty confident, it will probably be the right solution! :)

                  Sorry, I missed this reply - you are correct it's inside a larger loop, which iterates through each device - I'm going to try the ternary operator and see how that goes ...

                  Any idea how to put the number filter in there? The kW was to one decimal place, and the W was to 0 ...

                  Cheers

                    @richard-mortimer I believe when you did | number:1 and | number:0 was more than sufficient. alternatively just use point.value.toFixed(1) and point.value.toFixed() repectively

                    Do not follow where the path may lead; go instead where there is no path.

                      You would need another ternary operator. IMO the way you had it in the first place is easier to read.

                      If you use this pattern often, consider adding an AngularJS filter to a user module. You could then use it just like
                      <span ng-bind="point.value | formatPower"></span>

                        Thanks - the colon in the | number:1 was interfering with the ternary operator and getting it confused; so, while I could pipe it through, I couldn't modify the final number based on which direction it took - the point.value.toFixed(1) did the correct thing for me ...

                        Cheers
