Guide: Program an ESP8266 smart doorbell using ESPHomeYAML or Arduino IDE

My most recent video walks through modifying an $11 wireless doorbell from amazon to use MQTT to interface with home assistant to notify on ringing, switch the chime on and off, and track the state of the front door via a reed switch.

A big focus of the video is comparing the programming process in Arduino with the new ESPHomeYAML hassio addon by Otto Winter. Even if you aren’t interested in making a wireless doorbell, check out the video to see how easy it is to program an ESP8266 with ESPHomeYAML, no need to mess with libraries or portable installs, it just works.
