I have made an Arduino kit that acts as a weather station. It sends sensors data (DHT11 & LDR) to the ThingSpeak web server.
Now I want to perform some actions based on the data on the ThingSpeak server (like if temperature exceeds a limit turn on the fan, etc).
I've searched and I found that there's a React app on ThingSpeak, which will trigger events if data exceeds some values.
The problem where I got stuck is that I want to send a signal from the ThingSpeak web server to my ESP8266 (Arduino) to turn on/off the device connected to a relay on Arduino.
I've figured out that there's also a ThingHTTP feature which sends HTTP requests. But I don't know how to send requests/signals to my kit to perform some actions.
I've already spent 2 months building this project, and now I'm stuck in the last part. Please give your valuable suggestions and solutions.
