I am new to this forum,but I am happy to share with you some projects I've been working on with the ESP8266.
So the first one is about controlling AC I just wanted to have a easy way to control any AC using the IR protocol of the specific device not only sending the bytes I have read of a dump information based on the button that was pressed and after that I said ok but I want to be able to control it not only with my smartphone but also using my assistant and this is how: https://github.com/dimityrivanov/ESP-ACController was born.
You can also find the mobile application source code here: https://github.com/dimityrivanov/Android-ACController
The other project is password vault that allow you to store securely passwords and then read them out threw your smartphone and as well beam them over V-USB as keyboard you can find it here: https://github.com/dimityrivanov/WifiVault
