I am rather new to openhab and I am trying to learn as much as I can . I going through YouTube tutorials to learn and get into it.
With the help of this tutorial (sorry: in German) I wanted to learn about the network binding. It worked pretty good and I could manage to genereate a page as it is the goal in this tutorial.
However for the lastseen pointer to my mobile phone I get a wrong time displayed. It lagged by one hour until yesterday (winter time) and since today (summer time) the lag is two hours.
Can anybody imagine the reason and how I could solve this problem?
Check if the settings for the timezone are correct in
- Main UI => settings => regional settings => timezone
- on your OH host in: /etc/timezone
- on your OH host in /etc/default/openhab if in EXTRA_JAVA_OPTS something like
-Duser.timezone=Europe/Berlin is set
- in openhab-cli console you can check: env |grep -i timezone which depending on your timezone should result in something like:
String user.timezone Europe/Berlin
Thanks a lot @Wolfgang_S!
In openHAB the time zone is correct. Also in the System Settings of my Synology.
I just figured out that the time zone of my docker container was not correct. I changed it using this small tutorial and now it works!
Thank you so much!
