This video shows you how to take data that is stored in InfluxDB Cloud 2 and use it in a "Switch" node within Node-Red. In our example, we read the average house temperature and decide whether or not the heating should be switched on.

It takes you through:

• Creating an InfluxDB Cloud 2 account
• Creating a token to allow you to push data into InfluxDB
• Creating a task to automatically generate an average value from multiple devices
• Create a Read-Only token for Node-Red
• Installing the InfluxDB node in Node-Red and configuring it
• Creating a Flux query to read the data from InfluxDB
• Accessing the value from the query results
• Using the results in a Switch node to make decisions based on that data
