Get started in three steps

Flash your device, draw widgets, and display dashboard feeds anywhere on the web.

1. Connect your device

Flash the Ot Arduino library onto your ESP32 or ESP8266 board. Paste your generated project credentials, and watch it connect.

2. Build your dashboard

Drag widgets onto your workspace. Align charts, status indicators, control sliders, and relay toggles. Customize names and ranges.

Widget

3. Share your project

Every dashboard gets a secure, public URL. Share it with classmates, present at demo days, or export coordinates.

Your data, the way you want it

Ot offers native interactive widget cards powered by lightweight updates. Watch them live below.

Five lines. Your device is live.

We developed the OtDevice Arduino library specifically for low-bandwidth reliability. It supports ESP32, ESP8266, and Arduino WiFi boards out of the box.

Install it directly from the Arduino Library Manager in one click.

cpp
#include <OtDevice.h>

OtDevice device("YOUR_TOKEN", "YOUR_PROJECT_ID");

void setup() {
  device.begin("MTN_Momo_WiFi", "password123");
}

void loop() {
  device.send("temp", 27.5);
  device.send("moisture", 68.0);
  device.loop();
  delay(5000);
}
