Dears,
I’m impressed how simple the configuration of OpenHAB looks like, but struggling with some Details
For rrd4j-persistence it seems to be that only «openhab.cfg», «default.sitemap» and «rrd4j.persist» are needed to be configured. (see my files {i.e. extracts of the files} below).
The rrd-file exists: «volume1/@appstore/OpenHAB/etc/rrd4j/strom_w.rrd» (rights rw-r–r-- / Owner: openhab)
But unfortunatley the chart does not contain data (i.e. no y-axis data).
What do i have to configure/check in order to display the Data in the Chart?
