The use of the ESP8266 in the world of IoT

#90155 Hello, everyone,
I’d like to build a thermostat with esp8266 and interface it to Alexa via Sinricpro. I must say that I am not very experienced and practical with the Sinricpro code; for the moment I only took the sample program from Github library "esp8266-esp32-sdk-master" called Thermostat.ino.
I have entered all the data for the Wi-Fi and Sinricpro connection, but at the moment it connects to the Internet (I have the serial feedback) but not to Sinricpro and also from its site is offline.
Do you have any advice?
Thank you

P.S. I enclose the code for practicality

 * If you encounter any issues:
 * - check the at
 * - ensure all dependent libraries are installed

 * - open serial monitor and check whats happening
 * - check full user documentation at
 * - visit and check for existing issues or open a new one

#91373 HI,
you refer to this article ( ... ant-alexa/ ) to control appliances with Google Home and Alexa using Sinric Pro. You can use the code for references.

Also, visit their GitHub page to check the dependency. ... /
