After Reset of the ESP8266 it sends either a webhook ( http get request ) or a mqtt package to your smarthome. After that the esp8266 go into deep sleep. Both versions can be updated over OTA Webserver (second Button).

Thanks to AndyW83 for the initial Design of the Button. Andy also programmed the MQTT version for the Button.
