I have a Raspberry Pi 3 Model B. And I want to do my first project with it. I have an AC control panel that has a broken screen that was supposed to show the temperature. My idea is to connect my device somehow to it and control the panel remotely using simple commands such as (ON/OFF), set temperature and view status. (And maybe some cooler ideas that I don't know of as of this moment) I took these pictures of the control panel: I have no experience whatsoever with the Raspberry Pi or with the AC panel, however I have a small linux installed on it, and I understand that I can do some Python programming to control such things, and I think I don't have issues with that. So my question is, what should I connect with what and how? And is there some basic tutorials to projects similar to mine that I can follow?
I wrote some Python script to control my hot water , I used an opto isolated relay to switch the high voltage I STILL RECOMMEND STRONGLY IF YOU ARE NOT FAMILIAR WITH HIGH VOLTAGE YOU LEAVE THAT PART TO SOMEONE ELSE. I also used a 2x16 LCD Screen for output along with a push messaging service. I had this working but since moved on to a more advanced set up. It was one of my first Python projects so it's scrappy but it works. Maybe you would enjoy playing around with it ? Let me know if you do
