Mobile Application

Hi. I want to make my home smart with arduino and control it from mobile app which I created. But it is important that has to be worked in local. maybe it is possible with API of blynk or creating another server. How can I do that? Thanks in advance

What EXACTLY do you mean by this?


Imagine that I am in home and I have no internet connection. In this case system has to be worked.

The Blynk system relies on all communication going via the cloud server.
The app and the web console talk to the cloud server, and the devices (your Arduino in this case) also talk to the cloud server.
Without access to the cloud server (via the internet) then the app can’t communicate with your Arduino.
