I try to connect two ESP8266.
My project is to measure the temperature of 3 sections of our 3000lt Puffer of our wood heating sytem with a ESP826 and sending the values to a second ESP8266.
The second one will have a display witch shows the temperatures, so my mother can see it from her kitchen and dont have to run 10 times a day in the cellar to prevent of cooling down the heating system.
I found on the documentation sheets the “Communication between devices” section,and ist seems to be the right choice.
So first of all i try d to connect two devices and turn on/off a led:
thing[“onoffled”] << digitalPin(onoffled);
I understand it as when i go to the API Explorer there would appear a new resource. is this right?
when i open the API explorer the refresh sign turns and after a while it gives me a error message.
Can Anybodybody help me?
