Hello everybody,
I'm trying to link my esp8266 with Alexa and I'm facing few problems, this is my code I found

- I cannot connect to http://sinric.pro at all, all the tutorials I find over the Internet are about the old version sinric.com, what is supposed to put in the #define API_ENDPOINT line?
- I'd like to control one of the two GPIO pin I have, putting it HIGH and LOW with Alexa, and then, using one of the digital pins of Arduino, turn on the led, this should not be very complicated, but I cannot figure out twhich part of the above code should be changed..
- I would like to start from something very easy, i.e. turn on a led by saying to Alexa "turn on the led", but all the tutorial I find are about much more complicated projects with much more complicated board with a lot of pins(chronotermostats, PIR lightining and so on), can someone suggest me a site where I can find very simple project to begin to discover my module which has only two GPIO pin accessible (GPIO0 and GPIO2)?
Thanks a lot for your suggestions...
