Alexa2ESP

Ninty-nine personalized voice commands via the Alexa voice assistant for your ESPs, and 99 is a lot!

What is it.

This is a personal project gone public to example a simple way to use the Alexa Voice Assistant, dot or echo, to control an ESP8266 or ESP32. It enables ninty-nine project taylored voice activated control states for ESP devices. Alexa to/from ESP communications emulate a dimmable Philips hue light without the normal on/off switching.

Code is hacked from Fauxmo library.

Alexa2Esp is poorly hacked version of Xose Pérez's Fauxmo library, IMHO. The hacks eliminate Alexa's on/off state management to enable the 0 and 100 percent values for use as ESP command values. It also ensures that each Aleax voice command is received only once; an important feature for IR directives and toggel switches.

A user provided processing routine (FIFO loopback queueing method) establishes common command processing using "if-else" and/or "switch-case" like statements to validate and process the command within the ESP's current state.
