caldav platform allows you to connect to your WebDAV calendar and generate binary sensors. A different sensor will be created for each individual calendar, or you can specify custom calendars which match a criteria you define (more on that below). These sensors will be
on if you have an on going event in that calendar or
off if the event is later in time, or if there is no event at all. The WebDAV calendar get updated roughly every 15 minutes.
You might need some additional system packages to compile the Python CalDAV library. On a Debian based system, install them by:
sudo apt-get install libxml2-dev libxslt1-dev zlib1g-dev
To integrate a WebDAV calendar in Home Assistant, add the following section to your
# Example configuration.yaml entry for baikal calendar: - platform: caldav username: [email protected] password: !secret caldav url: https://baikal.my-server.net/cal.php/calendars/[email protected]/default
# Example configuration.yaml entry for nextcloud, calendars will be found automatically calendar: - platform: caldav username: john.doe password: !secret caldav url: https://nextcloud.example.com/remote.php/dav
This example will generate default binary sensors for each calendar you have in your account. Those calendars will be
on when there is an ongoing event and
off if not. Events that last a whole day are ignored in those calendars. You have to setup custom calendars in order to take them into account or for advanced event filtering.
You have the possibility to create multiple binary sensors for events that match certain conditions.
# Example configuration.yaml entry calendar: - platform: caldav username: [email protected] password: !secret caldav url: https://baikal.my-server.net/cal.php/calendars/[email protected]/default custom_calendars: - name: "HomeOffice" calendar: "Agenda" search: "HomeOffice" - name: "WarmupFlat" calendar: "Agenda" search: "Warmup"
This will create two binary sensors for the calendar name Agenda: “HomeOffice” and “WarmupFlat”. Those sensors will be
on if there is an ongoing event matching the regular expression specified in
search. In custom calendars, events that last a whole day are taken into account.
Please note that if you use the
custom_calendars option, only those calendars will be loaded. You cannot use
custom_calendars in the same configuration.
List of the calendars to filter. Empty or absent means no filtering, i.e., all calendars will be added. It cannot be used if
custom_calender option is used.
Details on any custom binary sensor calendars you want to create. Using this will only load the custom calendars supplied. No other calendars will load.
offset_reached: If set in the event title and parsed out will be on/off once the offset in the title in minutes is reached. So the title Very important meeting !!-10 would trigger this attribute to be on 10 minutes before the event starts. This should be in the format of
True/Falseif this is an all day event. Will be
Falseif there is no event found.
message: The event title with the
searchvalues extracted. So in the above example for
offset_reachedthe message would be set to Very important meeting
- description: The event description.
- location: The event Location.
- start_time: Start time of event.
- end_time: End time of event.
All events of the calendars “private” and “holidays”. Note that all day events are not included.
# Example configuration.yaml entry for nextcloud calendar: - platform: caldav url: https://nextcloud.example.com/remote.php/dav username: "me" password: !secret caldav calendars: - private - holidays
Full example with automation to wake up to music if not holiday. Prerequisite: you have a calendar named “work” where you create calendar entries containing “Holiday”.
Custom calendar names are built from the main calendar + name of the custom calendar. Using the option of
'.*' will load all calendar events.
# configuration.yaml calendar: - platform: caldav url: https://nextcloud.example.com/remote.php/dav username: "me" password: !secret caldav custom_calendars: - name: holiday calendar: work search: "Holiday" - name: vacation calendar: vacation search: ".*" # automations.yaml - id: wakeup alias: "worktime wakeup" trigger: platform: time at: "06:40:00" action: - service: media_player.media_play target: entity_id: media_player.bedroom condition: - condition: state entity_id: calendar.work_holiday state: "off"
