-
Update and flash your ESP8266 with "ESP8266/WebSocketClient/ESP8266_WebSocketClient/ESP8266_WebSocketClient.ino"
-
Create an API.ai agent and import "matrix-ai.zip" and setup Google integration and webhook
-
Test and enjoy.
Troubleshooting
-
Make sure Google Home device is logged in to same account as your API.ai account.
-
If unable to trigger relay power cycle the ESP8266.
-
If you are still unable to trigger the relay then restart Heroku app by selecting option "Restat all dynos" and then power cycle the ESP8266.
-
If you see crash errors in Arduino IDE serial monitor the use a better power supply.
-
Use a saprate power source for relay or use 5volts power source and use 3.3 voltage regulator to power ESP8266 from same power supply.
-
Make sure you enter the correct URL for webhook in API.ai
-
Make sure Google action option is enabled.

If it still does not work then go to church and pray to God -:)
