I am bulding a remote straight out of Harry Potter. It can control 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴. From tv's and air conditioning, to smart plugs, lights, computers (via wake_one_lan) and more. It has on off buttons, a screen to see what you are controlling, one knob to change volume or light intensity, 1 button to change the device and 2 configurable buttons to whatever you want.
This is my very own OS that can be run in the web!
It's very personal to me :D
