How to send Real-time data from ESP8266/DHT to Azure IoT Central Application

This video describes step-wise how to stream real-time data from ESP8266 also called NodeMCU to IoT Central Application with a well-known sensor, DHT. You will learn how to create custom templates and capabilities, and design/provision an IoT device in the IoT Central application. I have documented this project in my GitHub repository:

Hi everyone, Thank you for following my content and subscribing to my channel. Apologies if you are getting an error when you try to run the code.
I recently received a message from Microsoft on migration that happened.

"We'll be migrating some of your IoT Hubs and/or IoT Central Apps from the Baltimore CyberTrust Root to the DigiCert Global G2 root within the next two weeks, on 11 October 2023. Any devices that don't have the DigiCert Global G2 root added to your trusted root store won't be able to connect to the migrated IoT Hub or IoT Central App".

If you are in a position to debug the issue, let the community know, meanwhile i will be following with Microsoft team to assist.

However, i urge you to try debugging it 😃

Thank you so much for the video! Easy to follow and I learned a lot. The github portfolio was also of great help.

Thanks for this video, but this example is not function anymore after 2023, June 23. Something changed in connection and the authentication isn't working. If you know how to fix it, please share with us.

Hello Aron, Sorry to bother you. But I've been having this problem. your code as well as many others don't seem to be working in Northern Europe sever. I had some questions about your code. I didn't know where to ask.
1. connectowifi - I don't recognise this function and it doesn't look defined. What is the function block for unsecured no password devices.
2. Are you using stale code and video? I think the cert roots have changed


ERROR: MQTT client connect attempt failed. Check host, deviceId, username and password. (state -2) I always hang on this state. I have quadruple checked these.

@AronAyub Could you kindly provide me this Arduino code?

Hello AronAyub, Hope you are doing well! Thank you for sharing this amazing project with us! I am writing to ask if you have also tried sending ESP8266/DHT data to the Azure IoT hub? If yes, would you please also share your video with us? Thank you so much!😊
