OH2: my.openHAB stays offline

thopiekar · November 13, 2016, 10:54pm

Thanks! Do you think it would be possible to copy the current cacerts into my openHAB installation, modify my copy and use it for the openHAB session?

I would better try not to modify anything else then openHAB

Beats me. Maybe this could be accomplished inside the my.openhab addon. You should contact one of the developers. (I’m on the phone and don’t remember who that is)

@ThomDietrich Hmm, isn’t @Kai one of them?

I probably add some commands to my openHAB.sh script to download the latest JRE into my openHAB installation…

No, all I did was to create an OH2 compatible copy of the OH1 bundle.
Don’t know it it is possible to deal with lacking root CA certificate within the bundle without having to touch the JRE itself. Would have to investigate, but I am lacking the time - if someone has an idea and wants to come up with a PR, feel free!

@Kai Ah, ok, I saw that you’ve been working on the binding a long time ago.
Well, I’ve got no experiences in JAVA at all, but this is what I’ve did for the Cura project, where they also had this problem on OSX:

github.com

thopiekar/Cura/blob/master/plugins/SliceInfoPlugin/SliceInfo.py#L48


    Application.getInstance().getOutputDeviceManager().writeStarted.connect(self._onWriteStarted)
    Preferences.getInstance().addPreference("info/send_slice_info", True)
    Preferences.getInstance().addPreference("info/asked_send_slice_info", False)


    if not Preferences.getInstance().getValue("info/asked_send_slice_info"):
        self.send_slice_info_message = Message(catalog.i18nc("@info", "Cura collects anonymized usage statistics."),
                                               lifetime = 0,
                                               dismissable = False,
                                               title = catalog.i18nc("@info:title", "Collecting Data"))


        self.send_slice_info_message.addAction("Dismiss", name = catalog.i18nc("@action:button", "Allow"), icon = None,
                description = catalog.i18nc("@action:tooltip", "Allow Cura to send anonymized usage statistics to help prioritize future improvements to Cura. Some of your preferences and settings are sent, the Cura version and a hash of the models you're slicing."))
        self.send_slice_info_message.addAction("Disable", name = catalog.i18nc("@action:button", "Disable"), icon = None,
                description = catalog.i18nc("@action:tooltip", "Don't allow Cura to send anonymized usage statistics. You can enable it again in the preferences."), button_style = Message.ActionButtonStyle.LINK)
        self.send_slice_info_message.actionTriggered.connect(self.messageActionTriggered)
        self.send_slice_info_message.show()


##  Perform action based on user input.
#   Note that clicking "Disable" won't actually disable the data sending, but rather take the user to preferences where they can disable it.
def messageActionTriggered(self, message_id, action_id):
    Preferences.getInstance().setValue("info/asked_send_slice_info", True)

@ThomDietrich I added now commands to my script, which downloads, unpacks and uses the latest JRE on restart.
Also added a licence agreement message before the download starts.
Now after restarting OH2: “openHAB is online”

No idea how useful this can be here: http://stackoverflow.com/a/2313963/6333993

ThomDietrich · November 14, 2016, 2:15pm

Sounds good. Would you share it? Sounds like something others might be interested in as well.

Here ir preferably in a tutorial posting

thopiekar · November 14, 2016, 2:59pm

Yes, it will be commited to my openhab-qnap-qpkg repository soon. Just need to add additional commands for all the different architectures. There will be commands like: installJREarm32,installJREarm64, etc.
I could use “uname” to detect the architecture, but I think it is not worth it, as I’m sure you can fix that in the binding easily and updating JRE isn’t needed every day.
My solution is not very handy, because you’ll have login via SSH to your NAS and use the service script (/etc/init.d/openHAB.sh) to do this. But at least there is an alternative

Here it is:

ThomDietrich · November 15, 2016, 10:21am

Nice Even includes checksum verification

thopiekar · November 15, 2016, 2:13pm

The way it should be, isn’t it?
