Add-ons Bindings

Hi all,

I am struggling witht the configuration if the caldav bindings to integrate my Google Calendar. I alread read all manuals and threads but was not able to make the calendar integration work.

I installed the bindings, configured the .cfg files, items, things and sitemap.

The openhab.log is showing following error:

Do you might have an idea what could be wrong? I already allowed “less secure apps” in my Google Settings. If I enter the URL of the caldavio.cfg directly in the browser, I can download the file with my credetials.

Could you share your setup, please?

Sure, please find the setup in the following:

caldavio:mehl:preloadTime=20000 
caldavio:mehl:timeZone=Europe/Berlin 
caldavio:mehl:charset=UTF-8 
caldavio:mehl:LastModifiedFileTimeStampValid=false

kalender.items

}

Do let me know if you need further information.

First of all I would check the following .config files:

\userdata\config\org\openhab\caldavio.config
\userdata\config\org\openhab\caldavPersonal.config

Are they correct? If not, delete them and restart OH. They will be recreated during startup.

Next I would change URL to https. This is then using SSL = Secure Sockets Layer.

And adding this 2nd line also:

caldavio:mehl:url=https://www.google.com/calendar/dav/...@group.calendar.google.com/events
caldavio:mehl:disableCertificateVerification=true
