Hello everyone,
I have an issue with fairly simple task in NodeRed. For now I am trying to generate random data and display them on a chart.
Everything works fine but after I reload the page the chart collapses and becomes disrupted:
This is flow I am using:
flows.json (1.6 KB)
I have already looked into the issue here but the problem was with Raspberry PI Zero and it not able to connect to the NTP. Which shouldn't be a problem for me because I have an ethernet connection and when refreshing the page the device doesn't shut down.
Thank you all in advance!
