Are you using MQTT? If so then use a Retained Topic in MQTT for the current value.

Alternatively you can use persistent context for storing values. See [Working with context : Node-RED](https://nodered.org/docs/user-guide/context)

Have you watched this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot in about 1 hour. A small investment for a lot of gain.
