Freeboard Error

Question

Hi.

I try to recreate this project and followed the steps, but when i test the Push Monitor in api explorer it appears inactive, and from there on i can't run the Freeboard app.
Can anybody gave me advice where could i be wrong?

Those are the steps i make

1.Create a Push Monitor in api explorer digi manager
<Monitor>

2. Test the Push Monitor in api explorer digi manager

</result>

3. Perform a GET to https://dweet.io/get/dweets/for/00000000-00000000-00409DFF-FF5C525A-router-temperature to get the last five data points.

Can i upload files in this forum?

Answer 1

The Monitor you attempted to create in step 1 is not displayed in step 2. Be sure you have the path set to /ws/Monitor, the HTTP method set to POST, the content in the edit box, and then select the Send button. The response should display to the right and verify it has a 200 HTTP response code.

According to the pdf, step 2 shows the results, that the monitor is active (    <monStatus>active</monStatus>),
but in my case is not (    <monStatus>INACTIVE</monStatus>), so it is different from the monitor in step 1.

My path is set to /ws/Monitor.

According to the pdf, the HTTP method had to be set to GET (i try the POST method too, but also received error).

Answer 2

It doesn't look like you created any monitor, so I think you made a mistake on step 1.
You have to POST that payload in the API explorer or using your favorite Web service API tool.
Also I notice that the payload has a few extra spaces in it so take care to look for errors when you post the <Monitor> payload to create the first monitor.

In step 2:
The monitors that you're showing are internal monitors (used by the dashboard) to process changes to devices and are not one created manually by you.

Every tool does web APIs a bit different. In powershell the command to call a web API is "Invoke-RestMethod". You'll have to do some searching on the syntax because its quite different than the way you do it in curl.
Here is the microsoft documentation on the Invoke-RestMethod API. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/invoke-restmethod?view=powershell-7.1

I try the command ''Invoke-RestMethod'' and ''Invoke-WebRequest'', but in PowerShell the commands is also unrecognizable. Any help?

I've noticed that in digi remote manager- event log i receive messages with url address from the Digi cloud kit. So, i try to use this address in Freeboard (with JSON data source), in order to obtain sensor data, directly from the https://xbeegateway.herokuapp.com/api/monitor , but  i don't receive no data. Is my idea possible?

---

I'm not a powershell user so I don't have any advice on that. Perhaps try another Web API client that you're more familiar with.

I update the PowerShell and now, when i use  curl https://dweet.io/listen/for/dweets/from/thing name  i've got '''request time out'' response and i can't get  the ''listen'' response. Any help?
