Hi,
I have now worked out how to get my sensor data stored in global variables with the change node, so how do I get all the values into a file or an email ?
Thanks

By using the "write file" and "email" nodes. Read the help for each to get you started.
Unfortunately the help files "write File" and "email" don't really help me as there is no mention of using system variables within your text.
Thanks

Do you know how to get data from your variable into a message? As msg.payload for example?
What happens when you send msg.payload into a Write-file node?
Is it the same for the email node, or does the node help tell you how to get a message property into the email body?
I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
