Raspberry Pi Tutorials

The following tutorials provide step-by-step examples of integrating Raspberry Pi hardware with the SiteWhere platform.

Node-RED Installation

This tutorial provides a complete walkthrough for installing Node-RED on Raspbian and acts as a basis for other examples.

Node-RED DHT11 Sensor Tutorial

This tutorial builds on the initial Node-RED tutorial and illustrates how to read sensor data and forward it to SiteWhere with no coding. The flow registers the Raspberry Pi then monitors a DHT11 temperature/humidity sensor, forwarding the data to SiteWhere at an interval.

Node-RED DHT11 Server Logic Tutorial

This tutorial builds on the Node-RED DHT11 tutorial and illustrates how to use logic in the outbound processing pipeline to dynamically create alerts and issue commands to a device. The flow detects humidity levels above a threshold, generates an alert, then issues a command to the Raspberry Pi to flash an LED indicator.
