Hi all,
I'm building a Mango website to monitor some power meter via Ethenet. Below is my data point logging setting.

Today, my server disconnect or the meter disconnect, the server keeps logging last data value (see photo below)

From 3PM to 9PM, the server is disconnected so I expect the value should be 0.

Is there are any setting so I can make sure the logging value is 0 if server/power meter disconnected, therefore I or anyone can realize the abnormal and check the server/meter?

Thank you.

You should contact them via email.

Hello,
Can we add a Clear input option to a <ma-point-list>? I have a chart with 4 selectable points and I use below code to select points:

<md-input-container flex="50">
<label>Select Points 2</label>
<ma-point-list query="{deviceName: designer.parameters.dn}" limit="100" ng-model="myPoint2">
</ma-point-list>
</md-input-container>

Sometimes, I don't need to show value from all 4 points, sometimes 2 are enough, then how can I put a clear input option in <ma-point-list>?

@jared-wiltshire
Thank you for your explaination. Can you be more specific about "datebar.to" and what is it in mango? I mean, there should be something like "myPoint.value" to show/assign a point value or "myDevice.name" to show the device name.

Hello guys,

Is there any method to create a droplist where we can select multiple point with tick boxes to create a graph with it?

Hi guy,

I am reading the document of Mango V3 and V4, I find something like this:

 <ma-point-values point="point1" values="point1Values" from="dateBar.from" to="dateBar.to" rollup="{{dateBar.rollupType}}" rollup-interval="{{dateBar.rollupIntervals}} {{dateBar.rollupIntervalPeriod}}">
    </ma-point-values>

And also like this:

<md-button class="md-raised md-accent md-hue-3" ng-click="dateBar.preset ='DAY_SO_FAR'">
                TODAY
            </md-button>

What is datebar.from and datebar.to call? There should be a list of them, right?
And how can we know about something like 'DAY_SO_FAR'?
I think I read it somewhere. I tried Mango Javascript but I cannot find them.

@robmalone I think I also have to fall back to 3.7.7 because I face point unreliable. Not sure how to fix it. No correct answer in forum yet

@robmalone Can you solve the problem with V4? If you cannot access the system on localhost, please try changing port to 8443, (but don't forget to forward that port).

@cwangv
Can you please be more specific about this: Now, let's create the overview.js and overview.html files, inside pages/overview directory.
If I understand correctly, I have to create a folder named pages, and create another folder named overviews in public folder?
"/public/pages/overview"?

@cwangv said in Update on Tutorial:

@tungthanh500
did you get stuck on the module file path? If you did, that could be due to that is not the right path for V4.
try replacing 'v2' with 'latest' in the path name.

I am lost at Overview part, I don't know where to create pages/overview folder.

Hi guys,
As V4 are released, there are some major changes. Can you update the step on HAVC Dashboard Tutorial? I'm learning and was lost at the second article (https://docs-v4.mango-os.com/hvac-dashboard-development-create-overview-component)
