Raspberry Pi projects with MQTT: Python clients, gateways, sensors, Node-RED and dashboards connected to a cloud MQTT broker.
Turn a Raspberry Pi and any HDMI screen into a wall-mounted dashboard. A single HTML page subscribes to MQTT over secure WebSocket, and Chromium starts full screen in kiosk mode on every boot.
Wire a DHT22 to a Raspberry Pi, read it with Python, and publish validated temperature and humidity JSON over MQTT with retries, median filtering and error counters that keep bad readings out of your dashboards.
Ten practical Raspberry Pi 5 IoT projects that use MQTT for messaging, with the hardware, topic layout and starting code for each, from a home sensor hub to an AI camera and a factory gateway.
Build a small, headless Raspberry Pi Zero 2 W sensor node that reads a BME280, publishes environment and health data over MQTT 5, uses less power and survives months of unattended operation.
Measure voltage, current, power and accumulated energy with a Raspberry Pi and an INA219, publish the readings as JSON over MQTT, and learn when to use a CT clamp HAT for AC mains circuits instead.
Create an account, get your broker credentials and connect your first device — no servers to install, patch or scale.
