- Tue Apr 28, 2020 10:05 am #86794 Hello, I hope everyone is doing fine during this carantine time
So, I need some help with an IoT project im trying to build. I've successfully created a home automation system with esp8266 and a webserver. I'm using python and django for the webserver and the esp is connect with 8 channel relay. My issue is to be able to control a device with alexa. I did the example from sinric pro for a light and it turns on successfully. But when trying to merge the code from example and my code webserver + sinric pro doesnt not work together. Any ideas??

I'm ataching my code for this. The esp is connecting to the webserver under /home/get_relay_group_status and it's getting the json variables (r_status = false or true). I can also send merged code with sinric.

Code: Select all
#include <ArduinoJson.h>
#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>

const char* ssid = "wifiname";
const char* password = "wifipass";

const int relay1 = 05; // GPIO05
const int relay2 = 04; // GPIO04
const int relay3 = 00; // GPIO00
const int relay4 = 02; // GPIO02
const int relay5 = 14; // GPIO14
const int relay6 = 12; // GPIO12
const int relay7 = 13; // GPIO13
const int relay8 = 15; // GPIO15
