Storing data into variables | Node-RED Essentials | Tutorial

Working with contexts, flow and global variables in Node-RED is a valuable skill when building complex automations. Using JSON and JavaScript makes it a fairly intuitive experience in Node-RED.

Check out my video on the Function Node:    • Node-RED Function Node | Tutorial   Useful Links: Contexts: https://nodered.org/docs/user-guide/c...
