There is a feature request for this functionality.
If you are also interested in getting a calender event list, please vote for this feature: Calendar - new entitites that show a list of events with a certain scope
My use case is to show a list of upcoming events on a epaper display. I already tried some ICS/ICAL custom_components, however they all seem to have huge problems with reoccuring events (e.g. birthdays events).
I’m just curious if anyone has solved this. I can only pull the next event in a given calendar, but sometimes even that doesn’t work (perhaps because it’s more than X hours away?).
Is there any way to pull a list of entities/attributes for upcoming events? Ideally in Node Red.
Office integration and calendar works
I ended up figuring out how to get the Node Red integration to work and use the ical-events integration. The hard part was getting the right URL for the “iCloud - Secure” option to work since it’s not the standard URL you get from the calendar itself.
{{ entities[0].attributes.message }}
For anyone that comes across this in the future, here is my solution which was created based on the code provided here: Google calendar get more than one event - #11 by der-optimist
This will create and populate a new sensor, the attributes will contain all the upcoming events within X number of days and the state will be the next event date.
Install the AppDaemon addon and add the packages requests, datetime and humanize required in the python section of the configuration
Create a config/appdaemon/apps/calendar.py file with the following code

For future reference, you can now get a list of upcoming events using calendar.list_events.
This new service call was added in the 2023.7.0 release (Services can now respond) and is one of the first that’s able to provide a response.
Thanks Tara, would you know how to call this service (calendar.list.events)i n a Jinja template to use for a TTS announcement?
Sure Gar, here’s the example from the link I posted above.
service: calendar.list_events
target:
entity_id: calendar.school
data:
duration:
hours: 24
response_variable: agenda
The variable agenda will contain a list of all events scheduled in the next 24 hours. That’s just one way to use the service call. The documentation explains the service call’s options.
Sorry for my ignorance, yep understand that however I am trying to construct a script using macros, I am trying to construct a TTS response using a number of macros, I have worked out 3/4 of it, however the service call to agenda and retrieving the info eludes me.
Macros for “greetings”, “weather”, hopefully “Calanda 1 agenda”, “Calanda 2 agenda” and so on here is an example - see the ??? needs filling 
{%- macro getGreeting() -%}
{% if now().strftime(’%H’)|int < 12 %}
Good morning.
{% elif now().strftime(’%H’)|int >= 12 and now().strftime(’%H’)|int < 17 %}
Good afternoon.
{% else %}
Good evening.
{% endif %}
{% if is_state(‘binary_sensor.morning’,‘on’) %}
Today is {{ states.sensor.date_and_time.state }},
{% else %}
It is {{ now().strftime("%I:%M %p") }}.
{% endif %}
{%- endmacro -%}
{%- macro getWeatherToday() -%}
the Temperature in the living area is currently
{{states(‘sensor.dining_room_fan_temperature’)}} degrees, the Outside
Temperature is currently {{states(‘sensor.gw1100c_v2_1_3_temperature_1’)}}
degrees, We are expecting a high of
{{states(‘sensor.parkerville_temp_max_0’)}} degrees, with a low of
{{states(‘sensor.parkerville_temp_min_0’)}} degrees, the chance of it
raining today is around {{states(‘sensor.parkerville_rain_chance_0’)}}
percent.
{%- endmacro -%}
{%- macro getGarysAgendaToday() -%}
Garys agenda for today is Today is ???
{%- endmacro -%}
Thanks for sharing this!
I’m trying to read google calendar multiple ‘all day’ events and want automations on them (to use as birthday reminders).
I followed your scripts, but sensor.calendar_events isn’t being shown.
What did I do:
python_packages:
- requests
- datetime
- humanize
calendar:
module: calendar
class: calendar
token: !secret calendar_token
url: http://<myinternalIP>:8123
sensor_name: 'sensor.calendar_events'
calendar: 'calendar.verjaardagen_2'
days_to_display: 60
Question: Does this need to be the internal IP or my external (I’ve set a subdomain on my own domain to enter HA).
What am I doing wrong?
Does the appdaemon log show anything useful, eg. The HomeAssistant API failing?
The URL is used to make a call to the API to get the calendar events, the API may not be accessible externally so I use the internal url
Thanks for the quick reply!
I’m can visit the AppDaemon. I don’t see any logs (no data available) on main_log, error_log. Also ‘Dashboards’ doesn’t show ‘calendar’.
The AppDaemon Dashboard doesn’t show the calendar for me either. main_log only seems to show something for me when I have the page open and then save the calendar.py file, then the logs will appear.
Also the Token should be a long-lived access token, this can be created in the profile section of HA.
My appdaemon.yaml does not contain python_packages, I added my packages in the front end.
Ok thanks. So I need to do something with the access token?
How can I check if the python packages are installed correctly? Or if the calendar.py is even loaded by appDaemon? I don’t see it when viewing State > Apps …
You need to generate a long-lived access token, add it to you secrets.yaml with the name calendar_token.
The app should be visible in State > Apps, the fact that its not makes me think something is erroring before it completes, go to hassio/addon select AppDaemon and click the info tab to see if there are any errors
Okay, few step closer:
I was manually adding the packages via SSH. Thanks for hinting towards the frontend. There I found the Log tab as well. It hinted on the token couldn’t be found. So:
Created the long-lived access token and placed it into my secrets.yaml.
Now when I watch the log, all I get is:

The log began with downloading the resources which is good. Also it found the calendar as ‘all’ so, also good. Now I only get this issue.
I have not seen that error before, try uncommenting some of the self.log lines in calendar.py and then we can start to work out where it is getting up to
I uncommented line 36 self.log(_list) ; line 93 and 95 but It’s not logging.
ChatGPT to the rescue? It suggested to rename the module to my_calendar because calendar is also a build-in library.
So, that helped with the earlier issues. Now I’m getting the following error:
Error while loading calendar calendar.verjaardagen_2. Maybe connection problem
Do you have a google calendar setup with that name under Devices and Services in HA?
