Template for finding a specific ical calendar event

Configuration
1

I’m trying to automate my kid’s alarm in the morning, so it will automatically adapt if school starts later because of last minute scheduling changes. This is very important in puberty :wink:

Her school calendar is available through a published iCal calendar. So I just installed the iCal sensor custom component. It shows me 6 sensors for the next 6 events in the calendar. I would like to know: what is the start time of the first upcoming event containing a hyphen (-) in the summary attribute?

Can someone help me out with a template? I’m stuck, don’t know how to approach this.

Thanks in advance!

Copy-paste the following template into the Template Editor and confirm it reports the desired value.

{% set x = states.sensor
  | selectattr('object_id', 'match', 'ical_magister_')
  | selectattr('attributes.summary', 'search', '-')
  | map(attribute='attributes.start') | list %}
{{ x|first if x != [] else '' }}

It will report nothing (empty string) if none of the sensors contain a hyphen in their summary attribute (the screenshot you posted doesn’t show a hyphen in any of the sensors).
