I would like to ask for an advice. Basically what I want to do is RPI local server with web server, where I can display data from arduino sensors and from web page (web server) I need to be able send values to arduino (like temperature… arduino will manage everything else). The connection should be serial (usb) as I don’t want to use any shields.
I tried to use Home Assistant, but in the end I couldn’t pass data from web to arduino. Second one, which I tried was Blynk… but I couldn’t even connect the arduino to the RPI…
I’m using Arduino MEGA and RP-3
