Hi all, I am currently researching digital twins.  
I would like to know how we can make a digital twin with node red and docker. without the need to use the cloud only in my Raspberry.  
Any tutorials or links would be very helpful.  
thank you in advance

a digital twin of a simple installation: temperature sensor, LEDs and a small motor acting as a fan.  
all connected to the raspberry.  
**my goal is much more to know how to make a digital twin even if it's just a data capture from a sensor.**

Watch [this playlist](https://www.youtube.com/watch?v=ksGeUD26Mw0&list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6) to understand how node-red works and get some inspiration along the way. If that didnt help, [go through the documentation](https://nodered.org/docs/user-guide/).
