How to Take Data Stored in InfluxDB Cloud 2 and Use It in a "Switch" Node within Node-Red

Описание: This video shows you how to take data that is stored in InfluxDB 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
