I am using ESP8266 and Blynk. Everything works perfectly in online mode(meaning when internet is connected).
I am trying to make things work in offline mode(no internet but still connected to WIFI). I have tried http server on ESP8266 which works well though it doesn’t sync state when two mobile clients are connected.
How can ESP8266 publish to mobile apps that state has changed? What is the preferred solution here? I am reluctant to use MQTT Broker on Raspberry PI or create a hub etc.
Any solution here?
Thanks,
Vishal
