Hello all! I am new to rasberry and home automation. I have a question about multiple touch screens. I tried to find the topic in the forum but couldn't. I want to make a hom automation with multiple (best case 3 or 4) touch screens. On all of them I want to be able to access the system. (turn lights on and off, music an so on) It is still on planing phase. I just want to see if it is possible. So from a lot of reading the forum and youtube, it seems that it is difficult. I was thinking if it is not posible to use two or more displays in a system, maybe there could be one mqtt broker and a rasberry for every display, (the rasberry beeing a client). Or perhaps the system can use web server for control and the displays can log in and access application on the server... I am just spitbolling here. Does anyone have ideas? Or is it impossible. The system i have in mind may probably have arduinos for sensor control.
I appreciate any advice ! (also on a proper way of doing the system if I am missing something and you think you have a better idea )
