InstantIoT Server — Overview
InstantIoT Server is a small binary you install on a machine of your choice. It holds the state of your widgets, keeps a rolling history of sensor values, and routes messages between your ESP32 devices and the InstantIoT app on your phone.
It’s free and open source under AGPLv3 — source code at github.com/jeanloickdt/instantiot-server. It runs entirely on your own hardware.
What the server does
Three things, in plain words:
- Holds widget state — your dashboard survives reboots.
- Keeps a rolling history — view trends, not just live values.
- Routes messages between your devices and your phone(s) — many devices, many phones, one source of truth.
A web admin panel ships with the server for monitoring, user management, settings, and backups.
The server runs quietly in the background. The experience lives in the app — open it, connect to your server, and your widgets are right there.
