In this project I will be solving a problem that I had for a while. Since I love listening to music I always miss the doorbell. That is a big problem for me because there is always a postman at the door trying to deliver the components for the next project. So in this video I will show you how to add an ESP8266 to an intercom so that it can send WhatsApp/Telegram notifications to a phone. This way I and maybe you will never miss the doorbell again ;-) Let's get started!
