I have installed Java on my Synology and then openhab via the Docker and made all configurations as explained in the openhab tutorial, but unfortunately I cannot access openhab via the IP, the log also shows no abnormalities.
Does anyone have an idea what the problem could be?
Don’t install Java if using docker in the first place.The docker container brings its own Java implementation.
Which tutorial? There is an official documentation about the docker container:
But there is no howto, at least you have to connect some data from doc to Synology.
Please be aware that 512MByte RAM is very likely to be not enough RAM to run openHAB (keep in mind, that Synology itself will need a good amount of this RAM for its own job).
