I’ve a smart meter which gives the totals of used KWh and generated KWh by solar. As DB I use rrd4j. All item have as persistence strategy: everyMinute, everyChange, restoreOnStartup, everyUpdate, everyHour, everyDay. I can see that values are stored. If I analyse items, I see the totals of the smart meter. But when I choose Controls > Fixed > Aggregate I see bars. When I choose Day or Week(mon) and choose Series > Difference of lasts nothing happens. I see only the totals and not the differences. This have I a done before a couple of months ago and then I saw the differences. As far as I know I haven’t changed anything. I installed of course updates of Linux Mint Mate, Openhab and other programs. I have also made a full backup of Openhab, uninstalled en re-installed Openhab with the program manager of Linux Mint. Of course I also restored the full backup. That didn’t solve the problem.
What am I doing wrong or what have I missed in the updates of Openhab? Does any one know?
