I am using node-red in a docker container. The persistent data is stored outside the container in a named data volume. But the time series data from mqtt is lost every time the container is restarted. Is there a way to store this data as well, so that not all graphs are empty at every restart?
Welcome to the forum @polareisbaer
Are you storing the time series data, or are you relying on the chart to keep the data?
I keep the data only in the chart. So I want to keep the charts.
Of course, there are many ways to do this in Node-RED. Colin showed 1 but you could equally set up a file-based context store and use that instead.
