Thanks for the demo. Can we have a digital twin only in the raspberry using containers? Can we have a digital twin only in the raspberry using containers? one container to collect data from the sensor and send this data to the other container which will display it with the description of the environment?

[@basantkumar4900]

Hi, first of all wonderful video. Secondly can you guide me how to use rest API. Actually i have to update the telemetry data (6 fields) around 30 thousand every minute so i am thinking to use patch but looks like it cannot help. Can u guide how to achieve it.

[@pedzisanimoyo3717]

Geat vid, lots of possibilities. Does the DT influence the plant or it runs only as a model, the only interaction being data transfer from plant to DT?

[@industry40tvonline]

You can have the DT autonomously provide feedback into the plant, but maybe as a start, you'd want to have the DT suggest actions to a human being instead. Thanks for the feedback Moyo.

[@manishapal9223]

When I send data to the IoT-Hub, I don't see the data update in the explorer. How can I check if the data is properly formatted, is send to the right place and is picked up by Digital Twins ?

[@Hell0mynameisCathy]

How did you set up the raspberry pi? What hardware are you using to connect the sensor to the raspberry pi?

[@yongchanghe5576]

Hello sir, I recommend you create your IoT Hub by selecting an F1: Free tier. Because this tier should be free for us to use. You can find it in IoT hub > Management > Scale tier and units > Pricing and scale tier > F1: Free tier.

[@industry40tvonline]

Noted! Thanks for your feedback, Yongchang.

[@Deekudla]

Very informative and great presentation. Hello from India. Keep rocking. Can you please create a video on security aspects around digital twin architecture? second, I don't find device twin explorer in Github, could you please update the link

[@moiensiddikie423]

Hello I am new to the Digital Twin World can you Please tell me what Learning path I should follow to learn ADT and DTDL and from where I can Learn those skills .

[@govthamreddy]

Thanks for the demo. Can you explain where we can see Telemetry data in explorer, and also how we can send telemetry data to digital twin. Also can we use JSON object as property type in twin model?

[@industry40tvonline]

Thanks for the comment, Gowtham. It's not possible to see telemetry data on explorer as it requires backing storage. You can only see telemetry when you forward it to platforms like Time Series Insights. There are many ways of sending telemetry data to digital twin including the one I showed in the video which uses IoT Hub and Azure Functions.

[@12456hehe]

May i ask if your digital twin is able to predict the future state of your set up?

[@selvansenthil1]

Data streams from physical device to digital copy and we use that data for modelling.. anyhow the source of the data is physical device and we can model the data directly received from physical device. What is the need of digital device here?

[@judithnjoku7729]

Great content, but if only I can get past the errors i get when trying to run the digital twin explorer on local host

[@battleroyalec]

Does either c# or c++ work with digital twin development, or do I specifically need to learn JSON?

[@larajk_bts2399]

Sir can i create a digital twin for a patient using the tools that u used?

[@bim4u-getbimbenefitswithou924]

Thanks for a brilliant tutorial. In my own learning, I've run the DeviceSimulator (as per the MS tutorial) which generates data in the IoT hub, as expected. The DT is also recording published events. Nevertheless, when I run the simulation, for some reason, the twin properties in the ADT Explorer aren't updating in the way that you showed. Any ideas?

[@jatinshukla7009]

u get the zip file for digital twin explorer??

[@bim4u-getbimbenefitswithou924]

[@betterd9160]

The concept of digital twin was first, in my opinion, used in the movie 2001 Space Odyssey. In the 90s I thought Bluetooth would be used for this type of function but I was wrong.

Thanks for your comment.

Hi, great video! What if I already have a data file, in a time series forma. How do I send this data to the DT?

[@industry40tvonline]

Thanks for the feedback, Goncalo. Just curious to find out why you'd want to send time-series data to a digital twin. If anything, data should be moving from DT to your time-series DB. And maybe only use time-series data for contextualising real-time information that is being sent to DT.

[@goncalofelicio6738]

@@industry40tvonline well, the context is that I have timeseries data from a device, but not in real-time, only in datafile and I want to demo a DT of the device with this data to see it in the DT explorer or connect to the TSInsights and see it there

[@olaplassen1736]

What changes do you have to make to get this setup working with an BME280 sensor? Is it only the Rasberry Pi script that needs to changed? Great tutorial!

[@industry40tvonline]

Thank you, Ola. The idea is to publish the data to the IoT Hub connected to your function. It doesn't have to be a Raspberry pi, as long as your sensor has the capability to publish data to Azure IoT Hub it will work. So all you need to do is to repurpose the RPI script for your BME280 sensor.

Can you do this with arduino too?
