Hi there,
I want to setup several ESP8266 (wifi module) in a row. So if the first ESP8266 gets a message, he reads the message and when the message isnt intended to him, he send the message to the next ESP8266, and so on. Now I searched the web and couldnt find any examples, so I hope someone here can tell me if this is possible and how I can do that.
The case: I want to control serveral lights using relais with 70 meter between the lights.
