I think it should be mentioned in here:
http://docs.openhab.org/installation/rasppi.html
that java must be updated to get myopenhab/openHAB cloud connector working. I followed these instructions (found it from this community):
https://www.linuxbabe.com/desktop-linux/install-oracle-java-8-debian-jessie-raspbian-jessie-via-ppa
and now everything is working ok. As a beginner it is quite hard to get openHAB working without valid step to step instructions.
openHAB is great system, thanks to all developers!
Hello @Tommi,
While writing these instructions myopenhab was not considered as strongly. I agree, that this should be considered and made clear to users. I’ve created a ticket in the docs.openhab.org issue tracker, feel free to help out! https://github.com/openhab/openhab-docs/issues/194
