Using calendars to switch on lights, But..

[vapid bloom]

When there is a power outage and the power resumes after the start time and within the event duration, the automation does not work. How can i modify the code, very new to YAML. Thanks in advance.

alias: gate light
description: ""
triggers:

• trigger: calendar
  event: start
  entity_id: calendar.lighting_calendar
• trigger: calendar
  event: end
  entity_id: calendar.lighting_calendar
  conditions:
• condition: template
  value_template: "{{ 'Gate Lights' in trigger.calendar_event.summary }}"
  actions:
• if:
  • condition: template
    value_template: "{{ trigger.event == 'start' }}"
    then:
  • action: switch.turn_on
    target:
    entity_id: switch.outdoor_lights_2_switch_2
    data: {}
  • action: persistent_notification.create
    data:
    title: gate lights
    message: switched on
    notification_id: "10"
    else:
  • action: switch.turn_off
    target:
    entity_id: switch.outdoor_lights_2_switch_2
    data: {}
    mode: single

the way i would do this is:
create scene with lights on
create scene with lights off
then automation:
trigger: start
trigger: end
trigger: home assistant starts

action:
if block:
if light supposed to be on then activate scene with it on
else activate scene with it off

Instead of calendar start, you do a state trigger if the calendar entity turns on - that will trigger both when the event starts, and whenever ha restarts and the event is ongoing

But that won't work if you have overlapping events etc, so Michael's should work

mine is not perfect but its simple

The only thing I'd caution you on is that it might be annoying if the automation turns lights on, you manually turn them off for whatever reason, then ha restarts and it turns then back on or vice versa, so you might want to have some way of checking if the automation has already turned the lights on/off today and not run if that's the case

depends on how often you have power cuts i suspect. sometimes over engineering for corner cases leads to more problems

Thank you.. Being a newbie finding this a bit over whelming.. Let me see if I can do this
