Raspberry Pi and Node-RED: Open Source Tools for Local Automation and Industrial IoT applications
summary
Demonstrates that Raspberry Pi + Node-RED can handle small-to-medium industrial tasks not as PLC replacements but as low-cost, open source bridges to Modbus OPC UA and MQTT networks. Shows a production setup that does 1 Hz temperature read from an SHT31 over I2C, actuates a relay on a GPIO for on/off heating control, and scales into building automation. Includes MQTT-triggered bash execution for IP/VPN handling and a knitting machine integration that runs successfully.
