Overview Easy Alexa (Echo) Control of your ESP8266
ESP8266 is a very popular device for IoT these days. ESP8266 is easily available as a module. Its a small and dirt cheap device which has a inbuilt controller running at 80Mhz and with optional firmware it can be used as a stand alone device without a microcontroller like arduino.... 2-relay module works "better" than 1-relay module: in terms of accuracy LOW gpio -> relay on; HIGH gpio -> relay off. 1-relay module seems to trigger only once, and then keeps the relay on no matter the gpio value (just like if relay IN is always shorted to ground).
