Temperature chart with rrd4j

I reinstalled the persistence service, but the charts were still empty. The solution was very simple: because /etc/ and /usr/lib are only accessible as root the file owner of rrd4j was root. chown openhab … and i see the chart-lines. Thank you for your help - often the bugs are soo simple… Greetings!
