Different problems around rrd4j

rrd4j is the persistence default service in shapshot #1072 with openHABianPi and Windows10.

I checked previousState with 3 number-items and 3 switch-items (each one for everyMinute, one for everyChange and one for everyUpdate) and changed the states in a rule. All …/userdate/persistence/rrd4j/*.rrd files get installed, but only the files for everyMinute takes values. State-changes of the switch-items over the sitemap are correct stored in the rrd4j.


Only the msg is not correct “404 Unknown Item or persistence service” and was shown also if rrd4j is given

hc_140
I can’t store rrd4j!


No items are displayed!

What’s the reason?

rrd4j is known to be working reliable only with everyMinute:

The strategy everyMinute must be used, otherwise no data will be persisted (stored).

Try PaperUI, that should work.

HABmin is just not finished yet regarding some of the functionality.
