General CalDAV set up

Mark1 · May 18, 2016, 3:22am

I am trying to get the CalDAV binding to work on my OH1 system and have quite a few questions. I believe I have all of the files necessary installed in the addons folder.

org.openhab.io.caldav-1.8.2.jar
org.openhab.persistence.caldav-1.8.2.jar
org.openhab.binding.caldav-1.8.2.jar
org.openhab.binding.caldav-1.8.2.jar

My openhab.cfg file set up as follows. I have the refresh time set to be short for testing purposes.

################################### CalDAV IO Binding ###################################
#
# Used to connect to Cal DAV. All parameters are required.
# Path to the calendar
# caldavio:<calendarId>:url=
  caldavio:ohab:url=https://www.google.com/calendar/dav/me@mydomain.com/events
#
# Username for the calendar
# caldavio:<calendarId>:username=
  caldavio:ohab:username=username
#
# Password for the calendar
# caldavio:<calendarId>:password=
  caldavio:ohab:password=password
#
# Reload interval unit is minutes.
# Defines how often the calendar should be reloaded from server.
# Default is 60 minutes
# caldavio:<calendarId>:reloadInterval=
  caldavio:ohab:reloadInterval=5
#
# This defines which events are relevant for execution. Unit is in minutes.
# Default is 1 Day (1440 minutes)
# caldavio:<calendarId>:preloadTime=
  caldavio:ohab:preloadTime=5
#
# A caldav Server is just a webdav Server which list files. Some servers does not use the valid timestamp for modifications.
# If your calendar does not provide correct timestamps you have to set this false.
# Default is true
# caldavio:<calendarId>:lastModifiedFileTimeStampValid=
#
# SSL verification can be disabled, if you don't want to import the server certificate
# into the java keystore. This is just needed for self-signed certificates, where the
# certificate path cannot be verified. Default is false. Do not set to true if no SSL is used.
# caldavio:<calendarId>:disableCertificateVerification=
#
# Timezone for events which does not have a timeZone information.
# Normally this is not required
# caldavio:timeZone=
  caldavio:timeZone=America/Chicago

################################ CalDAV Command Binding ###################################
# see CalDAV IO Binding
# Used to execute commands if events starts or ends with an easy notation in the event description.
# commaseperated (e. g. openhab, anothercalendar)
# caldavCommand:readCalendars=<ids from caldav-io>
  caldavCommand:readCalendars=ohab

############################# CalDAV Personal Binding ################################
# see CalDAV IO Binding
# Used to toggle switch items for presence. Switched to ON if an event in the calendar occurs.
# And back to OFF if the event ends.
# Can also be used to show upcoming or active events
#
# Which calendars should be used to detect presence (comma separated)
# caldavPersonal:usedCalendars=<ids from caldav-io>
  caldavPersonal:usedCalendars=ohab
#
# If the location of the event is one of this identifiers, the presence will not be changed.
# Can be used for events which are at home or are just reminders. (comma separated, optional)
# caldavPersonal:homeIdentifiers=

The CalDAV items files has the following:

String oHABcalendarN1 "Name [%s]" <calendar> {caldavPersonal="calendar:ohab type:ACTIVE eventNr:1 value:NAME"}
String oHABcalendarP1 "Place [%s]" <calendar> {caldavPersonal="calendar:ohab type:ACTIVE eventNr:1 value:PLACE"}
DateTime oHABcalendarS1 "Start [%1$tT, %1$td.%1$td.%1$tY]" <calendar> {caldavPersonal="calendar:ohab type:ACTIVE eventNr:1 value:START"}
DateTime oHABcalendarE1 "End [%1$tT, %1$td.%1$td.%1$tY]" <calendar> {caldavPersonal="calendar:ohab type:UPCOMING eventNr:1 value:END"}

And the event in my calendar has the following:

Event Name : testevent
Location : none
Start Time : any
End Time : any
Description : BEGIN:sKitchenLightStatus:ON
                   END:sKitchenLightStatus:OFF

I based the files off of the binding page in the wiki. Do I need the CalDAV items file if the calendar entry is referencing items I have in my MiOS items file?

I have the logging turned on to TRACE for CalDAV and here is the most recent output. I had just stopped the service added an event for 30 minutes in the future that should have been picked up.

Any help guidance would be greatly appreciated.

Hi,
Maybe some suggestions after a quick run through your data:

next to org.openhab.binding.caldav-command-1.8.0.jar I have also org.openhab.binding.caldav-personal-1.8.0.jar installed.
out the “caldavio:timeZone=America/Chicago” this might lead to problems.
in items file I have used type:EVENT

Maybe also have a look at:

Cheers

Yeah, I just realized my typo. It should be command and personal bindings in my jar list. I will try commenting out the timezone and changing the item type and see what happens.

I am not sure what is going on or what setting I have flipped or not flipped but it still doesn’t work. I tried several different calendar entries and commenting out the timeZone value. I even added a new item to the caldav.items file that had a value set by the calendar event and configured a rule based on the item value. Still nothing works.

How often should the system poll the calendar for entries? I even set the reload interval in the config file to ‘2’ (it is minutes right?) and it didn’t seem to reach out like it should. I had to restart the service after waiting 20 minutes for it to attempt to pick up a new calendar entry I added.
