#80749 Adding an Arduino in between, is a better idea. When I have to work on such projects where embedded & cloud computing is involved then I try to keep things separate & clear.
So, I connect all my sensors & output modules etc with Arduino UNO or NANO and do the server coding etc on NodeMCU or Arduino YUN etc. I use Serial Port for communicating data between the two.
