Several ESP8266 in wifi network should share information I am currently working on a project for my home where several ESP8266 (each with a relay) control lights. I have developed an android for this where I find the ESP8266s via mdns but the problem is that sometimes one or two won't be found ever (depends on the position where I am trying it). So my idea was to make them talk to each other so everyone knows like an list of ip addresses from the others. This would give me the possibility to find every ESP as soon as i have found one.
I guess you are asking if it is feasible: if this is the case, I would say yes, without too many troubles. Each ESP can launch MDNS discovery, so they can discover each other.
