bevor I have made my update from openHAB 2.1 to 2.5.9 I had an rrd4j database for e.g. logged temperatures. Now, i would like to have this feature again and I think it is still there … anywhere inside.
I still have my (old) rrd4j.persist file ind the related folder
Changes relating the a persistence service? Especially for rrd4j?
The only problem I notice in your .persist file is the missing everyMinute strategy for the last couple of items. Did that work before?
What is not working?
Are you trying the keep the history ( by using the .rrd from the updated installation)? Didyoumove those files? Are the access rigths correct?
Do you have more then one persistence service installed? Which is the default?
Thanks for your posting. The truth is, that I didn’t install any service for persiting data because I wasn’t able to find a binding or anything like this. That is the reason, why I ask for a setup (step-by-step tutorial or something similar).
Relate to your question “did that work befor”… yes in the former version, it seams to work, but the last 3 lines where add a feq hours ago and I detect there the mistake about the strategy your talked about.
“What is not working?” … the storage of Data. Wenn I look at “http://openhab:8080/rest/persistence” it looks quite empty. Means at “Rohdaten” (I Think “Rawdata”) I only the some brackets … [ ]
The update to version 2.5.9 was a complete new installation on a new sdcard.
Installing rd4j via PaperUI shouldbe straigth forward.
On PaperUI select Add-ons on the side menu, then Persistence on the on thetop menu, thatwillpresent youtheinstallable services. Move to rrd4j andclick the"Install".
Since you have already the rrd4j.persist file theservice should start immidiatly.
Give it some time and then you can use the REST API to fetch the stored data.
Your description is the way that I would expect … but … on the Add-ons-Side there are only “Bindings”, “Misc” and “Voice” but inside of all tree menu topics ther is no persistence option/selection available. Do I have to unlock this somewhere?
