My.openhab: openHAB is Offline


I am having a problem with the connection between my openHAB and my.openhab.
I installed openHAB v. 1.8.3 on Raspberry Pi2, with HABmin and mqtt.
Used the apt-get installation method. Java SE RE is version 1.8.0_65 (the default from Raspbian Jessie).

Installed Z-Wave USB stick with a Fibaro Wall Plug, and created a test site with items. Works like a charm! Also from the ios app.

Tried to setup my.openhab. Installed my.openhab addon, found Secret en UUID, from the /usr/share/openhab/webapps directory and created an account on
Copied and pasted the Secret and UUID over to
Created /etc/openhab/configurations/persistence/myopenhab.persist with the following content:

// persistence strategies have a name and a definition and are referred to in the “Items” section
// myopenhab.persist
Strategies {
default = everyChange
Items {
* : strategy = everyChange

In openhab.log I noticed these these msgs, which concerns me, in particular ‘config is null’:

2016-08-03 17:32:07.093 [DEBUG] [o.o.i.m.i.MyOpenHABServiceImpl] - config is null

Searched the forum, but could not find an item describing this. Hope someone can help me
with this issue.

Kind regards, Bert

It maybe will not solve your whole problem, but at first you should update java/install the newest version. See this thread:

Since they use a new certificate for my.openhab since yesterday, old java versions do not support this certificate anymore.

If you are german, you can find a possible helpful tutorial for my.openhab installation here:

Or an english tutorial (scroll further down):

In this tutorial it’s mentioned that Raspbian Jessie comes with JRE 1.8, but it’s not set as default. Maybe this already is the problem?


Hi Stefan,
That did the trick. in ny openHAB site is now Online.
Thanks for your tutorial on your site. I might need it still.
Having the next problem, I do not see any devices:
No Devices
You currently have no devices registered with my.openHAB.

So i have to search further.
And your German language tutorial is no problem for me, i live in Die Niederlande. Ich kann ziemlich Deutsch lesen.

Vielen Dank für Ihre Antwort
Grüße, Bert

Could you explain what did the trick?
I am new to this and I am not sure how to send a notification message through my.openhab.

Thanks Stefan, your german version did the trick. If only more people would mention openhab needs a restart.oddly though your restart command did not work, so i just restarted my raspi.
Thanks, hope that was the last hurdle for a while

Yes, updating java helps.
