Setting Up Node-RED to Transmit Wzzard™ Data to Microsoft Azure IoT Hub
How to publish data from Wzzard Mesh Edge Nodes into the Microsoft Azure IoT Hub using Node-RED
NOTE: This assumes your Gateway is set up and claimed on WebAccess/DMP (formerly SmartWorx Hub) and the Refrigeration demo flow is loaded and working. NOTE: This assumes that the user has an Azure account.
Prepare the Gateway
• Log into WebAccess/DMP and manage your device.
• Select Devices > View Devices and select your Device ID.
• Under Manage Apps, ensure RSMessageBroker, Wzzard Mesh and NodeRED are installed. If not, install them by selecting the Add/Upgrade Apps tab.
