How to start the temperature/humidity app on device?

[MrRoyce]

I think I have every thing set up, but my chart is still blank. Working with support, they sent a screenshot of their device terminal window that shows the device sending temperature and humidity data. My device just shows the SendEventAsync message as shown in the Get Started tutorial.

@MrRoyce Thanks for your feedback! We will investigate and update as appropriate.

Hello @MrRoyce , can you double check if your value for the key Azure.IoT.IoTHub.ConnectionString is the iothubowner connection string?

Please also validate that the messages sent by the device have the following json format:

{"messageId":1,"deviceId":"my Device","temperature":22,"humidity":70}

Thank you.

Hi there thanks for following up. Yes the connection string is correct. The problem I have is getting the device to Send temperature data.

How do I get the device to do that?

I tried to make changes to the code also and ensured that the settings as defined in the documentation. Even now I am getting Blank Chart. I used SimulatedDevice.cs code shared via Git.

Can someone please provide end-to-end solution to this issue. Looks like something very silly is happening somewhere :(. Look forward for your support in fixing this issue

Hi there. Can you show me how the messages look like on the IoTHub side? To see messages coming in IoTHub you can use Azure IoT Toolkit extension for Visual Studio Code.

Thank you!

Here is the terminal window from my Hub.. Is this what you are asking for?

Hello, I was expecting to see messages coming in with a format like {"messageId":1,"deviceId":"my Device","temperature":22,"humidity":70} after you "Start Monitoring D2C Message"

Which Get Started tutorial did you follow prior to this? To complete the tutorial on this doc successfully you need to firt complete the following:

If you set up a simulated device you need to make sure that the messages sent are in Json Format and follows the structure {"messageId":1,"deviceId":"my Device","temperature":22,"humidity":70}.

As an easy test you can use Visual Studio Code to simulate a message on any device already created:

After that the web app dashboard should have a new entry.

Thank you.
