Use OpenHAB Cloud Connector to send notification

[Nexollo (Nex)]

I am trying to setup openHAB Cloud Connector but it keeps telling me I’m offline

I checked the log and it says

2019-03-30 23:09:00.082 [WARN ] [o.openhabcloud.internal.CloudService] - You are running Java 1.8.0_65 - the openhab Cloud connection requires at least Java 1.8.0_101, if your cloud server uses Let’s Encrypt certificates!
2019-03-30 23:12:02.259 [INFO ] [io.openhabcloud.internal.CloudClient] - Shutting down openHAB Cloud service connection

I tried searching how to update to java 1.8.0 101 but can’t find the commands for raspberry pi.

Also it gives an error when I try to send a notification using this

var NotificationAction = org.openhab.io.openhabcloud.NotificationAction;
NotificationAction.sendBroadcastNotification(“This is a broadcast test”);

The error is

java.lang.RuntimeException: java.lang.ClassNotFoundException: org.openhab.io.openhabcloud.NotificationAction.sendBroadcastNotification
at jdk.nashorn.internal.runtime.ScriptRuntime.apply(ScriptRuntime.java:397) ~[?:?]

I don’t know if the Java version is causing the notification not to be sent, if not how would I fix that?

I don’t know if the Java version is causing the notification not to be sent

my.openhab won’t work at all with that old java version.

@Nexollo

if not how would I fix that?

Please use the search function in this forum, there are many topics about that.

I’ve tried searching but none give simple and easy to follow instructions on how to simply update to the 101 version.

My.openhab.org is online // iOS app doesn't show sitemap -> Solution: Java update!

I did -almost- the same, but used the WebUpd8 installer in @Udo_Hartmann link to get automated java updates in the future (I wasn’t aware that this is not done automatically through apt-get update/upgrade on a Raspbian Jessie installation on a Raspberry Pi), but you have to make a slight change to the tutorial: instead of su - use sudo su: sudo su echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" | tee /etc/apt/sources.list.d/webupd8team-java.list echo "deb-src http://ppa.…

Make sure you are using version 8, not the newest verison 11 (not yet fully working with openHAB)

Does your method from that post only give java 8 updates when they are released? I got it to update and it works now but my notifications still aren’t sending, do you know the problem there?

Log says

Caused by: java.lang.ClassNotFoundException: org.openhab.io.openhabcloud.NotificationAction.sendBroadcastNotification

@Nexollo

do you know the problem there?

Notifications are enabled (see “Mode”)?

They are enabled, I have it set to notifications and remote access.

Then I have no more ideas, sorry.
