I’d like guidance on an IoT issue with ESP8266 in the communication part. My ESP has been programmed with Arduino, has a Webserver running on it, It has Static IP, it’s connected to a router in my house, in my house also has a Static IP on the internet. I’ve created a mobile app wich access the Static IP of my house and sends a command that should reach the ESP8266 device. The goal is to make the communication in real time, where by pressing a button in the app, will immediately trigger “something” in the ESP.
My question is:
How does the command sent from my cell phone find the ESP8266 device connected to the router?
IMPORTANT: I don’t wanna have to change anything on my router, that is, I don’t want to access my router settings to redirect requests to the IP of the ESP8266.
