# ThingsBoard Telemetry

Day 49 of the 100 Days 100 IoT Projects collection. Board: Pi Pico.

Stream DHT11 telemetry to ThingsBoard and control an LED via RPC on the Pico 2W. Industrial-grade IoT dashboards.

## How it works

The Pico 2W publishes DHT11 readings to ThingsBoard over MQTT, where they appear on industrial-style dashboards and trigger rules. In the other direction, RPC calls from the dashboard reach back down to toggle the board's LED. Telemetry up, commands down, one protocol.

## What you'll learn

- MQTT telemetry
- RPC remote control
- Industrial IoT dashboards
- Bidirectional device messaging
