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: enter image description here 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?

    As you can see on the bottom right photo, all wiring of the control panel is connected to mains, so it is LIVE; see the two vertical lines marked L and N for live and neutral. If you don't have experience and the knowledge to work with mains voltages and currents, as well as proper isolation and handling procedures, keep your fingers off this part and let the mains interfacing part getting done by someone with proper training. – TheDiveO Jul 21 '17 at 15:19
  • Thanks for the warning! I'll be sure to do my research before attempting to do anything with the wires. – ddsds Jul 22 '17 at 9:12

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

  • Thanks for the answer. Actually I would be interested in seeing your project if that is ok with you. In general I would like to implement my Raspberry Pi with my household devices and experiment with them, and I think your project would be a good asset to help me understand the different possibilities of that. If you know any good websites that provide easy to follow projects that would be great as well! – ddsds Jul 22 '17 at 9:15
