How to list multiple calendar event in a template

[berkans (Berkan Sezer)]

I know that calendar.list_events has been changed with get_events

But now below working template became unavailable

template:
  - trigger:
      - platform: time_pattern
        minutes: /1
    action:
      - service: calendar.get_events
        data:
          duration:
            hours: 2191
            minutes: 0
            seconds: 0
          start_date_time: "{{ today_at() }}"
        target:
          entity_id: calendar.dogum_gunleri
        response_variable: scheduled_events
    sensor:
      - name: Calendar Scheduled Events
        unique_id: calendar_scheduled_events
        state: "{{ scheduled_events.events | count() }}"
        attributes:
          scheduled_events: "{{ scheduled_events.events }}"
        icon: mdi:calendar'

Do you have any idea about where I am making the mistake ? The above was used to work fine before.

I’m in the same situation, it seems that the response variable is a bit different with calendar entity as first “level”.

calendar.family:
  events:
    - start: "2023-12-14T20:30:00+01:00"

I’ve tried to modify my variable with all sorts of combination:

    - variables:
        events: >
          {{ scheduled_events[0][events] | sort(attribute='start') | list }}

Dot notation, bracket notation, name, postition etc. but I can’t get it to work

edit:
This is working after several attempts:

- trigger:
    - platform: time_pattern
      minutes: /5
  action:
    - service: calendar.get_events
      data:
        duration:
          hours: 168
          minutes: 0
          seconds: 0
      target:
        entity_id:
          - calendar.family
          - calendar.holidays
          - calendar.garbage
      response_variable: scheduled_events
    - variables:
        events: >
          {{ scheduled_events["calendar.family"].events + scheduled_events["calendar.holidays"].events + scheduled_events["calendar.garbage"].events }}
  sensor:
    - name: Calendar Scheduled Events
      unique_id: calendar_scheduled_events
      state: "{{ events | count() }}"
      attributes:
        scheduled_events: "{{ events }}"
      icon: mdi:calendar

You are wonderful as always. Thank you very much.

[alexd123]

Another working example using the new service, as dictionary format has changed slightly:

service: calendar.get_events
data:
  start_date_time: "{{ today_at('00:00').strftime('%Y-%m-%d %H:%M:%S') }}"
  end_date_time: "{{ today_at('23:59').strftime('%Y-%m-%d %H:%M:%S') }}"
target:
  entity_id:
    - calendar.my_personal_calendar
response_variable: my_agenda

followed by

service: notify.mobile_app_my_samsung
data:
  title: Today's events
  message: >-
    {%- if my_agenda['calendar.my_personal_calendar'].events  %} Today's events:
      {%- for event in my_agenda['calendar.my_personal_calendar'].events %}
        {{ event.summary }} {% if event.start is defined %} {{ as_timestamp(event.start)|timestamp_custom('%I:%M %p',True)}} to {{ as_timestamp(event.end)|timestamp_custom('%I:%M %p', True)}}
        {% else %} All Day
        {% endif %}
          {%- if event.descripton is defined %} - {{ event.description }} Details: {{ event.descripton }}
        {% endif-%}          
        {%- if event.location is defined %} at {{event.location }} 
        {% endif -%} <br> 
      {%- endfor %}     
    {%- else %} No upcoming calendar events today. {%- endif %}

Hi togehter,

it seems there are a lot of calender experts in this post

I opened a new topic because i need help (I am new and lost ):

https://community.home-assistant.io/t/calender-meetings-of-today-into-sensor/656488?u=uli1900

please take o lokk on my new topic. Thanks

@Didgeridrew (sorry, the answer function and the mention with the help of @ seems redundant).

I would like to summarize all appointments of the next 72h of my three existing calendars and output them in one entity.

Unfortunately, I have no idea how to program, so I used the modules available here for my code.

However, I strongly suspect that an error has crept in here, because nothing is displayed.
The source of the error seems to me to be the merging of the three scheduled_events under “schedulded_events:”.

Unfortunately, I can’t solve this on my own and would therefore like some help.

Is it correct that I insert this code completely into my sensor.yaml?
Do I need another entry in my configuration.yaml?

I would be very grateful if someone could help me!

Attached is the code:

  - trigger:
      - platform: time_pattern
        minutes: /1
    action:
      - service: calendar.list_events
        data:
          duration:
            hours: 72
            minutes: 0
            seconds: 0
          start_date_time: "{{ today_at() }}"
        target:
          entity_id: calendar.familie
        response_variable: familie_scheduled_events
      - service: calendar.list_events
        data:
          duration:
            hours: 72
            minutes: 0
            seconds: 0
          start_date_time: "{{ today_at() }}"
        target:
          entity_id: calendar.soraneu_gmail_com
        response_variable: soraneu_scheduled_events
      - service: calendar.list_events
        data:
          duration:
            hours: 72
            minutes: 0
            seconds: 0
          start_date_time: "{{ today_at() }}"
        target:
          entity_id: calendar.viking1144_vk_gmail_com
        response_variable: viking_scheduled_events
    sensor:
      - name: Calendar Scheduled Events
        unique_id: calendar_scheduled_events
        state: "{{ scheduled_events.events | count() }}"
        attributes:
          scheduled_events: "{{ familie_scheduled_events.events + soraneu_scheduled_events.events +
        viking_scheduled_events.events }}"
        icon: mdi:calendar'

I wish you a happy new year!

@hpoperator

Is it correct that I insert this code completely into my sensor.yaml?
Do I need another entry in my configuration.yaml?

No, this configuration does not belong in sensor.yaml. The current method for configuring template sensors, which allow triggers and actions, uses template as its top-level key, not sensor. You can either create a template: block in your configuration.yaml file, or use the !include tag to have your template integration-based configuration split to their own file(s)

Also, the available calendar services have been updated to address the issue of returning data from multiple calendars in one call. The service calendar.list_events is being phased out and will be remove in 2024.6. Instead use calendar.get_events.

template:
  - trigger:
      - platform: time_pattern
        minutes: /1
    action:
      - service: calendar.list_events
        data:
          duration:
            hours: 72
            minutes: 0
            seconds: 0
          start_date_time: "{{ today_at() }}"
        target:
          entity_id: 
            - calendar.familie
            - calendar.soraneu_gmail_com
            - calendar.viking1144_vk_gmail_com
        response_variable: calendars
      - variables:
          ev_list: |
            {% set ns = namespace(cal_events=[]) %}
            {%- for key, value in calendars.items() %}
              {%- for event in value.events %}
                {%- set ns.cal_events = ns.cal_events + [event] %}
              {%- endfor %}
            {%- endfor %}
            {{ ns.cal_events | sort(attribute='start') | list }}
    sensor:
      - name: Calendar Scheduled Events
        unique_id: calendar_scheduled_events
        state: "{{ ev_list | count }}"
        attributes:
          scheduled_events: "{{ ev_list }}"
        icon: mdi:calendar'

[hpoperator (Andy)]

First of all, I wish you a happy new year!
You are my hero! With this code it definitely worked and I have already made the appropriate adjustments to calendar.get_events.
Now I have added or displayed the entity calendar_scheduled_events on my dashboard using a condition card in which an entity card is integrated. Unfortunately, I can only see how many appointments are pending, but not in how many days and also not what this appointment is called (value from line “summary”).
What do I have to change to display this accordingly?

Best regards

[Didgeridrew]

You’re not going to get what you want with an Entity card. You can get something basic with Markdown.

type: entity-filter
entities:
  - sensor.calendar_scheduled_events
state_filter:
  - operator: ">"
    value: 0
card:
  title: Upcoming Calendar Events
  type: markdown
  content: >-
    {%- for l in config.entities %}
    {% for e in state_attr(l.entity, 'events')%}
      \- {{e.start }}: {{e.summary }}
    {% endfor -%}
    {%- endfor -%}

But, you might be better off using a purpose-built card, like Atomic Calendar Revive to handle displaying calendars/events.

maybe someone here has an idea how to get whole-day events of tomorrow only?

Get all calendar day events of tomorrow

Hi, I try to get all whole-day calendar events of tomorrow. Here is my template code: - trigger: - platform: time_pattern minutes: /1 action: - service: calendar.get_events data: duration: hours: 24 minutes: 0 seconds: 0 start_date_time: "{{ (today_at('00:00') + timedelta(days=1)).strftime('%Y-%m-%d %H:%M:%S') }}" target: entity_id: - calendar.abfall response_variable: scheduled_events_abfall …

[apreick]

Hello, I would like a trigger for an automation?
one from the list of attributes.

For example, the “summary: 900 test”

Can you help me?

[Tombo8b (Thomas)]

I’m using the template from hpoperator but the events are not sorted. I tried some variants but the events are not sorted.

See the template here:

- trigger:
    - platform: time_pattern
      minutes: /1
  action:
    - service: calendar.get_events
      data:
        duration:
          hours: 720
          minutes: 0
          seconds: 0
        start_date_time: "{{ today_at() }}"
      target:
        entity_id: calendar.familienkalender
      response_variable: scheduled_events
    - variables:
        ev_list: |
          {% set ns = namespace(cal_events=[]) %}
          {%- for key, value in calendars.items() %}
            {%- for event in value.events %}
              {%- set ns.cal_events = ns.cal_events + [event] %}
            {%- endfor %}
          {%- endfor %}
          {{ ns.cal_events | sort(attribute='start') | list }}
  sensor:
    - name: Familienkalender Events
      unique_id: familienkalender_events
      state: "{{ ev_list | count }}"
      attributes:
        scheduled_events: "{{ ev_list }}"
      icon: mdi:calendar'

[eftimg (eftim)]

@Tombo8b

{%- for event in value.events %}

Not sure if this will work for you, but maybe change to the below and remove your other sort?

{%- for event in value.events|sort(attribute='start') %}

[Didgeridrew]

I don’t see how that is working at all… The template that defines the event list variable isn’t referencing your response variable.

[Vandana (Vandana Dass)]

Hello Everyone,

I have added local calendar integration and added two events in the single calendar which repeats monthly.

eg.

Event 1 is due date for electricity bill.
Event 2 is due date for water bill.

Kindly guide how to create two sensors for each event and get how many days are left for the next event.

{{ (state_attr('calendar.events', 'start_time') | as_timestamp - today_at('00:00') | as_timestamp)/(60*60*24) }}

The above returns the days left for the first event only. How to get for both the events ?

Thank you.

[tomik67 (Tomasz)]

I used an SSD1306 OLED screen
I took the liberty of using your solution, my code looks as follows:

      - id: page9
        lambda: |-
          // Print next four collection
          char *strFam = strdup(id(cal_garbage).state.c_str());
          char delim[] = "~";

          char *nxtStrFam = strtok(strFam, delim);

          if (nxtStrFam != NULL && strlen(nxtStrFam) > 0) {
            it.printf(4, 0, id(font3), TextAlign::TOP_LEFT, "%s", nxtStrFam);
          }

          nxtStrFam = strtok(NULL, delim);

          if (nxtStrFam != NULL && strlen(nxtStrFam) > 0) {
            it.printf(128, 0, id(font3), TextAlign::TOP_RIGHT, "%s", nxtStrFam);
          }

          nxtStrFam = strtok(NULL, delim);

          if (nxtStrFam != NULL && strlen(nxtStrFam) > 0) {
            it.printf(0, 17, id(font3), TextAlign::TOP_LEFT, "%s", nxtStrFam);
          }

          nxtStrFam = strtok(NULL, delim);

          if (nxtStrFam != NULL && strlen(nxtStrFam) > 0) {
            it.printf(128, 17, id(font3), TextAlign::TOP_RIGHT, "%s", nxtStrFam);
          }

          nxtStrFam = strtok(NULL, delim);

          if (nxtStrFam != NULL && strlen(nxtStrFam) > 0) {
            it.printf(0, 34, id(font3), TextAlign::TOP_LEFT, "%s", nxtStrFam);
          }

          nxtStrFam = strtok(NULL, delim);

          if (nxtStrFam != NULL && strlen(nxtStrFam) > 0) {
            it.printf(128, 34, id(font3), TextAlign::TOP_RIGHT, "%s", nxtStrFam);
          }

          nxtStrFam = strtok(NULL, delim);

          if (nxtStrFam != NULL && strlen(nxtStrFam) > 0) {
            it.printf(0, 63, id(font3), TextAlign::BASELINE_LEFT, "%s", nxtStrFam);
          }

          nxtStrFam = strtok(NULL, delim);

          if (nxtStrFam != NULL && strlen(nxtStrFam) > 0) {
            it.printf(128, 63, id(font3), TextAlign::BASELINE_RIGHT, "%s", nxtStrFam);
          }

this is one of ten screens that shows/renders every 93 seconds.
Unfortunately, the problem I have with it is that this code overflows the RAM memory and the ESP32 restarts approximately every 3 hours and 20 minutes.

Does this code generate some variable that fills the RAM memory and should be removed during the next rendering cycle?

My configuration.yaml.:

  - trigger:
      - platform: time_pattern
        # This will update every hour
        hours: "/6"
    sensor:
      - name: Garbage Data
        icon: mdi:calendar
        state: "OK"
        attributes:
          cal_garbage: >-
            {% set items = state_attr('sensor.garbage_scheduled_events', 'scheduled_events') | sort(attribute='start') %}
            {%- for item in items -%}
            {% set delta = (item.start) | as_datetime | as_local - today_at() %}
            {%- if delta.days == 0 -%}
            {% set start = "Dzisiaj " %}
            {%- elif delta.days == 1 -%}
            {% set start = "Jutro " %}
            {%- elif delta.days == 2 -%}
            {% set start = "Pojutrze " %}
            {%- else -%}
            {% set start = as_timestamp(item.start) | timestamp_custom('%d %b ', default=0) %}
            {%- endif -%}
            {{start + '~'}}
            {{item.summary + '~' }}
            {% endfor %}

Have you ever had a problem with RAM overflowing?

[xxLeoxx93]

May I ask for you advice? When I create an automation based on you code the “ev_list” variable remains empty without any errors.
My Code:

alias: Get Events
description: ""
trigger: []
condition: []
action:
  - service: calendar.get_events
    target:
      entity_id:
        - calendar.xxx
        - calendar.yyy
    data:
      duration:
        hours: 170
        minutes: 0
        seconds: 0
    response_variable: calendars
  - variables:
      ev_list: |
        {% set ns = namespace(cal_events=[]) %}
        {%- for key, value in calendars.items() %}
          {%- for event in value.events %}
            {%- set ns.cal_events = ns.cal_events + [event] %}
          {%- endfor %}
        {%- endfor %}
        {{ ns.cal_events | sort(attribute='start') | list }}
mode: single

[Didgeridrew]

What does the Trace show?

[123 (Taras)]

FWIW, here’s another way to do the same thing. The result is a sorted list of consolidated calendar events. However, if you couldn’t get Didgeridrew’s code to work then it’s unlikely this will.

  - variables:
      ev_list: |
        {{ calendars.values() | map(attribute='events')
          | sum(start=[]) | sort(attribute='start') }}
