The Smallest WiFi Button in the World (ESP8266, MQTT, IFTTT)

This tutorial is showing how to built a small WiFi/Dash button for an ESP-01 module. A button and a LiPo Battery is added. The case is 3D printed. The software is based on Mongoose OS and sends notifications to an MQTT server and IFTTT over a direct web link. The video is also showing a possible use case for such a button.. enjoy watching.
