Page 21: Turning The Temperature Controller Into An Iot-Device
Quick Start Guide for Starter-Kit IoT with u-create Web and Node-RED 7.2. Turning the temperature controller into an IoT-device Now that the temperature controller is running on the u-control PLC, let’s connect it to an MQTT broker to turn it into an IoT-device. We will use the free test broker of mosquitto.org for this guide. First, we need to install the string node via the Node-RED palette. -
Page 22: Further Information
Quick Start Guide for Starter-Kit IoT with u-create Web and Node-RED To see which values the controller is publishing via MQTT you need to subscribe to the topic “weidmueller/starter-kit-iot/+” using an MQTT subscriber of your choice. The free command line utility mosquitto_sub is shown below.
