This project mainly relies on Blynk Server running at ftm.ddns.net (a custom Blynk Server Running on a Raspberry Pi), it's publicly available but protected authentication and SSL.
A custom app created on Kodular is also used for fast opening when comparted to the default Blynk app on Android. (10x faster).
This repository contains all the files necessary for adding OTA capability to Blynk and other projects on NodeMCU.
