Take a look under the directory ā¦\conf\services\ for a file called rrd4.cfg
Okayā¦ but Iām not finding much instruction on what to put in that file?
This is what would have been in my old ārrd4j.persistā file on OH 1.xā¦
// persistence strategies have a name and a definition and are referred to in the "Items" section
Strategies {
// for rrd charts, we need a cron strategy
everyMinute : "0 * * * * ?"
}
Items {
// rrd4 database are good for short term storage so we store AllItems mainly for the restoreOnStartup feature.
AllItems* : strategy = everyChange, everyMinute, restoreOnStartup
}
Thought I may as well try just copy my rrdj4.persist file from my OH1.x systemā¦ No luck though 
2017-01-26 15:10:32.645 [ERROR] [.eclipse.smarthome.model.persistence] - [org.eclipse.smarthome.model.persistence.manager(79)] The unsetModelRepository method has thrown an exception
java.lang.NullPointerException
Configuration and use of persistence in OH 2 is almost identical to how it worked in OH 1. The only differences are:
- instead of putting configuration parameters for the persistence (e.g. URLs, logins, etc) into openhab.cfg one uses a separate config file (e.g. rrd4j.cfg).
- setting the default persistence engine is done through PaperUI or in runtime.cfg
.persist files and calls in the rules are all identical to what you are used to. If you have made no customizations to the rrd4j configs in your openhab.cfg, you can ignore rrd4j.cfg.
What about the Strategies and Items we used to define in the old .persistence files?
Itās all the same. Same strategies, same way to assign Items to strategies. In fact, the OH 2 docs right now just point to the OH 1 wiki.
When I migrated I didnāt have to change one character in my .persist files.

Can I pay one of you to port my openHAB 1 to 2? 
But yeah, I mean it 
Thank you manā¦ this is really helpful i learn a lot and understand it very well especially I am a beginner on openhab2. I am looking forward for the continuation of the next part of this tutorial.
Cheers mate.
Great tutorial! But still missing something. In the tutorial, you mentioned configuring z-wave, but there was no mention of a Z-Wave Controller (physical hardware) that was installed. Iām just starting out with OH/2, in general. So please pardon my ignorance.
Wondering if the following setup is possible:
Raspberry Pi + OH2 + Smartthings Hub (that acts as a controller for all Z-wave devices)

I am trying to find any documentation which have some example how-to use MQTT, Arduno on Openhab. There is lot of videos on youtube but no description how they build there project. If I can get a link on tutorial then I can start my project.

Hi,
thanks for the tutorial. Iāve started using OpenHABian and followed the beginners tutorial in the docs. But I am a little bit confused if I should configure things in Paper UI or in textfiles to also have it available in the Basic UI.
I configured Philips Hue in Paper UI. Works great, easy to configure. Then I wanted to adjust my sitemap for basic UI. Do I really have to configure everything again textbased (.things file, .items file and .sitemap)? Because if I do that these configs also affect the Paper UI and I will see i.e. the Hue Bridge twice. Also the lights which I configure are visible again in the other tab in Paper UI.
In my opinion the things and items are already configured through Paper UI - I only want to have it visible in Basic UI. What did I misunderstood here?
Best regards,
Andy
Only the sitemap needs to be in a textual format. It can refer to the items that youāve made in paper UI.
sitemap default label="Main Menu"
{
Text label="Bedroom" icon="bedroom"
{
Frame label="Bedroom Light"
{
Switch item=Bedroom_Light_Switch
Slider item=Bedroom_Light_Dimmer
Colorpicker item=Bedroom_Light_Colour
}
}
}
Hmm I thought that Iāve tried thatā¦but now it works!
Thank you!

Iāve got open hab 2.2 installed. In paperui add-ons have no tab for persistence. Should I have one like in your screenshots or has this functionality been removed?
Is there an update to this tutorial? I am trying it and I didnāt get the page with āSimple, Standard, Expert, Demoā. It went straight to a page with "Home, Basic UI, Paper UI, and Habpanel. (Next step of tutorial shows just the first three). I blundered along trying to guess what I should do next to try to follow.
I got to adding my cellphone and I didnāt get to select Online and Time. I got Online, Latency (ms), and Last Seen. When I went to Control My phone shows up but it indicates āOnline (not). Latency (ms) -NaN, Last seen -ā
I have gone through the tutorial many times in case I missed something but the results are always the same.
Color me confused.
Which tutorial are you referring to?
This one?
You may always change your first choice later by editing your addons.cfg:
# Valid options:
# - minimal : Installation only with dashboard, but no UIs or other add-ons. Use this for custom setups.
# - simple : Setup for using openHAB purely through UIs - you need to expect MANY constraints in functionality!
# - standard : Default setup for normal users, best for textual setup
# - expert : Setup for expert users, especially for people migrating from openHAB 1.x
# - demo : A demo setup which includes UIs, a few bindings, config files etc.
#
# See http://docs.openhab.org/configuration/packages.html for a detailed explanation of these packages.
#
#package = expertI am referring to the tutorial described in this thread.
I canāt get my installation to math the tutorial.
Iāll try to see if I can understand your link.
Change
#package = expert
to
package = expert
and restart openHAB
