openhabian3 on RPi4:
I am getting these errors for two of my items:
2021-06-09 12:19:00.836 [ERROR] [d4j.internal.RRD4jPersistenceService] - Could not create rrd4j database file '/var/lib/openhab/persistence/rrd4j/Motion_Kitchen.rrd': Read failed, file /var/lib/openhab/persistence/rrd4j/Motion_Kitchen.rrd not mapped for I/O
I saw another post which said that it comes from using persistence for switches which is supposed to only be for numerical values:
It sounds like I can delete those files & fix this but I am using the default persistence configuration. I am assuming this happened because I chose these items to appear in a graph? My memory is that the graph DID show the switches state properly. Anyway, am I right that this was teh cause of these errors?
Is there a different configuration to use if you want persistence for switches?
