I had the problem that my chart data was deleted when I deployed my workspace. I was able to solve this topic using this subflow:
But I'm wondering if my file system will be damaged if there is a periodically (every minute = 1440 times a day) access to the file system (USB stick or SD card). Therefore I tried to add a feature to save the chart data manually, before I'll deploy my workspace. And I found this example:
Now I want to mix both features:
- Store chart data manually (e. g. using the inject node)
- Load data automatically
As I am a Node-RED rookie, I need some help to implement that!
