I want to build home automation with ESP32.
I want features: Online and offline working.
For example, I have 4 no. ESP32 installed at home and I have 5 mobiles.
3 mobiles in local should operate the lights and 2 from the cloud should operate the lights at the same type.
When the internet is not connected still local mobile should communicate properly.
What type of communication I need to implement MQTT or Http or MQTT+Http Or any other protocol.
Is there any web tutorial available where can I understand this thing or any example project?
Thanks in Advance.
