Google say next day calendar events

Hi, I’ve been all over documentation and forums to crack this one, but I’m stuck.

In a script, I want to test if calendar events are happening tomorrow, and if they are, get google to TTS them in a certain format as part of an evening notification.

My problem is the else-statement. I want google to tell me if there is nothing planned for tomorrow if none of the above ifs are true. How can I structure or wrap the statements to get the described outcome?

Thanks in advance!

{% if general.general test%}

  {% if is_state_attr('sensor.ical_shared_activities_event_0', 'eta' , 1 ) %}
  {{state_attr("sensor.ical_shared_activities_event_0", "summary") }} 
  {{as_timestamp(state_attr("sensor.ical_shared_activities_event_0", "start")) | timestamp_custom 
  ('%H:%M') }}
  {% endif %}

  {% if is_state_attr('sensor.ical_shared_activities_event_1', 'eta' , 1 ) %}
  {{state_attr("sensor.ical_shared_activities_event_1", "summary") }} 
  {{as_timestamp(state_attr("sensor.ical_shared_activities_event_1", "start")) | timestamp_custom 
  ('%H:%M') }}
  {% endif %}

  {% if is_state_attr('sensor.ical_shared_activities_event_2', 'eta' , 1 ) %}
  {{state_attr("sensor.ical_shared_activities_event_2", "summary") }} 
  {{as_timestamp(state_attr("sensor.ical_shared_activities_event_2", "start")) | timestamp_custom 
  ('%H:%M') }}
  {% endif %}

  {% if is_state_attr('sensor.ical_shared_activities_event_3', 'eta' , 1 ) %}
  {{state_attr("sensor.ical_shared_activities_event_3", "summary") }} 
  {{as_timestamp(state_attr("sensor.ical_shared_activities_event_3", "start")) | timestamp_custom 
  ('%H:%M') }}
  {% endif %}

  {% if is_state_attr('sensor.ical_shared_activities_event_4', 'eta' , 1 ) %}
  {{state_attr("sensor.ical_shared_activities_event_4", "summary") }} 
  {{as_timestamp(state_attr("sensor.ical_shared_activities_event_4", "start")) | timestamp_custom 
  ('%H:%M') }}
  {% endif %}

{% else %}
Nothing is happening tomorrow
{% endif %}

Anybody got any ideas?
