I’m not sure I understand, sorry 
. As far as I know I’m just using the built-in google calendar integration.
I have 7 automations that use the calendar triggers. I think they are all quite normal, based on the example in the docs. They all get the data from a single calendar ‘house_events’.
4 out of the 7 have a single condition like this:
trigger:
- platform: calendar
event: start
entity_id: calendar.house_events
condition:
- condition: template
value_template: "{{ 'Z-wave front door lock battery refresh' in trigger.calendar_event.summary }}"
2 out of the 7 have a double condition like this:
trigger:
- platform: calendar
event: start
entity_id: calendar.house_events
condition:
condition: and
conditions:
- condition: template
value_template: "{{ 'Activate morning scene' in trigger.calendar_event.summary }}"
- condition: state
entity_id: person.tim
state: 'home'
1 has a triple condition like this:
trigger:
- platform: calendar
event: start
entity_id: calendar.house_events
condition:
condition: and
conditions:
- condition: template
value_template: "{{ 'Morning News Briefing' in trigger.calendar_event.message }}"
- condition: state
entity_id: person.tim
state: 'home'
- condition: state
entity_id: media_player.tim_echo_dot
state: 'standby'
Edit: I just noticed that last one is using trigger.calendar_event.message instead of trigger.calendar_event.summary! That field may well be empty on that calendar item. I’ve edited my yaml, will see if that fixes my error.
