Hi all.
first of all, please be gently with me - cause im pretty new to this HA
How do i count and display number of events in local calendar in a template
can someone please help me with this?
I just want to display a number on how many events and tasks for today…
So i can use it in a notification on my mobile.
“You have 3 events and 2 task in your calendar today”…
i have search the web, but can’t find anything that does this for me…
best regards…
There’s no easy way to get this information into a template sensor currently. You can get this information in a notification without a template sensor.
calendar_events_today:
alias: Calendar Events Today
sequence:
- service: calendar.list_events
target:
entity_id: "{{ calendar }}"
data:
start_date_time: "{{ today_at() }}"
end_date_time: "{{ today_at() + timedelta(days=1) }}"
response_variable: agenda
- service: notify.your_mobile_device
data:
message: You have {{ agenda.events | count }} events in {{ state_attr(calendar, 'friendly_name') }} today
Then you can use this script anywhere
service: script.calendar_events_today
data:
calendar: calendar.abc
Thank you so much, Mister.
It works like a charm 
Once again, thank you
Apologies for bringing up an old thread, but I’m trying to do the same, but I’m struggling with the first block of code… is that an automation or a script?
I’ve added the code to both of those but when I run the second block of code as a script, I keep getting “UndefinedError: ‘calander’ is undefined”.
I’ve also tried to rename instances of calander to my local calander entity, but with the same ressult. 
I’d appreciate any additional guidance that you could provide.
Thanks in advance!
Thanks Taras for the response - got it working!
Hello everyone,
Sorry to dig up an old topic, but when I try the code you gave @petro , it throws an error : Message malformed: extra keys not allowed @ data[‘calendar_events_today’]
I must be missing something, but I can’t tell what… any idea ?
You put it in the script section of your configuration.yaml.
