InstantIoT is a mobile IoT app to control your Arduino, ESP32 (S2/S3/C3/C6) and ESP8266 boards from your phone. Design a dashboard, watch your sensors live, and let automations run on their own. The app even writes the sketch for your board, so you just add your pins and sensors. Reach it from anywhere over the Cloud, or nearby over Bluetooth and Wi-Fi.

Built by a maker, for makers. Not a platform sized for a factory: an app sized for the project on your bench, that grows when the project does.

CLOUD, BLUETOOTH OR WI-FI

InstantIoT Cloud
Your device connects over Wi-Fi or Ethernet; the app reaches it from anywhere. History of your signals, automations that run on their own, push notifications and e-mails — even with the app closed. The last value of every signal the moment you open the app. One account, every phone.

InstantIoT Direct
Your phone talks straight to the device, over Bluetooth or the device's own Wi-Fi. The phone and the device are the whole system. Perfect for the bench, a robot, a demo, the first minutes with a new board.

Same app, same widgets, same sketch — one line of begin() decides the path. A Direct project becomes a Cloud project the day it earns it.

17 WIDGETS, ONE GRAMMAR

Controls
• Buttons (simple, advanced, emergency)
• Switches (classic, segmented)
• Horizontal and vertical sliders
• Joystick and direction pad

Displays
• Gauges, levels, metrics, text
• Virtual LEDs
• Bar charts
• Charts with history — minute, hour, day — and selectable ranges

A widget looks at a signal. Swap the gauge for a chart: the sketch does not change.

AUTOMATIONS THAT RUN WITHOUT YOU

Build if-this-then-that rules that run day and night, even with the app closed:
• When the temperature goes above 25 → send me a notification
• When the tank drops below 60 % → stop the pump
• When the device goes offline for 5 minutes → e-mail me
Chains, waits, schedules — and the notifications tab keeps what they did.

THE APP WRITES YOUR SKETCH

Place your widgets, tap Copy template: the Arduino sketch arrives with every widget already wired to its signal. You add what only you know — your pins, your sensors, your actions:

ISwitch(I6, bool on) {
digitalWrite(FAN_PIN, on);
}

timers.every(10000, sendTemperature);
InstantIoT.write(I1, celsius);

Upload from the Arduino IDE you already use. The connection is handled by the open-source InstantIoT library.

COMPATIBLE HARDWARE

Thirteen boards, the same app:
• ESP32, ESP32-S2, S3, C3, C6
• ESP8266 / NodeMCU
• Arduino UNO R4 WiFi, MKR WiFi 1010, Nano 33 IoT, UNO WiFi Rev2
• Arduino UNO, Nano and Mega 2560 with an Ethernet shield or a Bluetooth module
Over Wi-Fi, Ethernet, the board's own Wi-Fi network, Bluetooth LE or Classic.

WHAT A MAKER DOES WITH INSTANTIOT

• Control a device from the phone — from the next room, or from another city
• Read a sensor on a gauge, a level or a chart, and scroll back through the week
• Get notified when a value crosses a threshold
• Run several devices in one project, several projects in one app, one project on several phones
• Export a project and share it, import one from a friend
• Keep the firmware: the app never hides what the device does

WHO IT'S FOR

• Makers with a real project on the bench — a greenhouse, a workshop, a weather station
• Arduino and ESP builders who want the app and the connection done, and keep the firmware
• Students in IoT, robotics and automation

You build the device logic. InstantIoT connects the experience around it.
