This is a little Arduino sketch as a firmware replacement for the Sonoff Touch light switch with Alexa support.
All the hard work was done by this guy, so thanks a lot. If you want more information on how it works read his blog post ;-)
With this firmware you can say something like this: "Alexa, turn on the kitchen light".
Basic setup:
// IP settings if you want static ip.
IPAddress ip(192, 168, 178, 50);
IPAddress gateway(192, 168, 178, 1);
IPAddress subnet(255, 255, 255, 0);
#define WIFI_SSID "####" // SSID of your wifi
#define WIFI_PASSWORD "####" // Your wifi password
String device_name = "###"; // The device you call alexa for (e.g 'kitchen' -> say "Alexa, turn on the kitchen light")
I flashed the firmware with the Arduino IDE with the following settings:
'Generic ESP8266 board' and Flash: (1M, 64K SPIFFS)
