Ot Documentation

Ot is an IoT dashboard platform built for makers, schools, and classrooms. Connect an ESP32 or Arduino-compatible board, stream sensor readings over MQTT, and watch them live on dashboards you assemble yourself — no backend code required.

How Ot works

Data flows through the platform in four stages:

Stage	What happens
1. Device	Your board reads sensors and publishes JSON to an MQTT topic using the OtTelemetry Arduino library. The only credential it holds is its `device token`.
2. Bridge	The Ot telemetry bridge authenticates the token, matches the device to your account, and stores the reading.
3. Storage	Readings land in the platform's built-in storage, or in your own Supabase database if you connected one.
4. Dashboard	Widgets poll for new readings and update live. Alert rules run on each reading and can notify you.

Designed for low bandwidth

A reading is a single small MQTT message. Devices work fine on modest WiFi, and dashboards refresh with lightweight polling rather than heavy streams.

Guides

Quickstart

From a new account to live sensor data on a dashboard in about 15 minutes.

Devices & Tokens

Arduino Library

Install the OtTelemetry library and stream readings from ESP32/ESP8266.

Dashboards & Widgets

Build canvases with charts, gauges, value cards, switches, and alert feeds.

Alerts

Trigger in-app and email notifications when readings cross thresholds.

Sharing & Gallery

Publish projects publicly, get cloned, collect likes and comments.

Your Own Database

Route your telemetry into your own Supabase project for full data ownership.

Troubleshooting

Fix devices that show offline, missing data, and connection problems.
