My idea is creating a Wifi Remote Device (ESP8266) to control other ESP8266 (remote), I have succeed to push (write) one value to Digital Pin on remote ESP, unfortunately I can not find a way to read the remote Digital Pin … This (remote digital pin) value is needed since I want to create a toggle mechanism …
Further more on the remote device to preserve the batt I will shutdown the device in any given time …
Any suggestion for work around?
