I am working on a automation system where 1 raspberry pi is running a server and a database. I need this raspberry PI to communicate to multiple slave devices (such as arduino UNO or NANO or other simmilar board). The number of slave devices might be up to 50.
I have created a server on my raspberry pi and using QT Creator to make querys and that part works fine. My major concern is how to make the raspberry PI talk to to slave devices and vice versa.
The slave devices have sensors...
RS-485 vs Ethernet for a large automation system network
