Okay I copied the file to the location described:
/config/.storage/local_calendar.RHS23-24.ics
Then I went developer-tools/services and input the following:
But I get an error - Failed something. What am I missing? Do I need to create the local calendar entry first?
Ok. Let’s go step by step, ok?
Go to UI and create manually empty calendar. Just create a new calendar. You may create a new item here as well.
A new calendar also you can see at the left menu at your HA dashboard.
At this step in HASS folder /config/.storage/ you can see a new .ics file with name entity what you create a 1 minutes ago.
Please do not move next while you a not pretty sure 
what you can see a new brand file in HASS folder.
The next step is very easy - just replace - override this file with own. Attention again please keep name as is! Do not need to rename etc file. Ok?
The last step is reloading calendar in HASS. Just GOTO to dev menu and make a some magic like you show before in the screenshot.
That’s all talks (c)
And btw. Keep in mind what name in Unix is case sensitive!
RHS23-24.ics And rhs23-24.ics and rHs23-24.ICS two big differences
Thank you for the complete explanation. I guess I missed the fact that I needed to use the UI to create the calendar in the first place. Now everything is working!!
Hi guys, I followed @10der his instructions but somehow something goes wrong.
I had an empty calendar and put the ics in place with the same name: no result.
Then I created a new calendar and put the ics in place with the new name: no result either. (it seems I had to add an event so that the ics file in HA gets created)
Next, deleted all calendars and started over again: no result.
What happens also: after reloading the service the calendar is gone from the calendar application whereas it still shows up in the integration but the entity is unavailable.
I checked the linux file permissions and they are OK so it’s not that.
What am I missing?
A two question here =)
thank you @10der for explaining this.
but honestly… why is there no simple import button?! is almost unbelievable
Hi, local calendar developer here. It just needs to be designed and added. Keep in mind this is done in volunteer time, so someone has to be motivated to do this.
I personally don’t have a use case for this so I haven’t done it myself yet, but it’s been on the bark burner " Todo list" for awhile. (I put time on Todo lists instead)
Sir, hi
First of thank you
Second, thank u a very much for this component
And last. My IMHO one feature is absent: can’t able to setup RRULE 
Hi, thanks!
Can you elaborate? Rrules are supported. Maybe you mean via service calls is a gap? Yeah that’s true, only supported in the UI right now.
yep! Lack of calling API.
I searched for a similar thing.
Once a year we get a new trash day calendar via a PDF file from a company that is taking the trash.
Then I must manually add all entries to 5 calendars (mix, plastic, glass, paper, bio).
Ideally, I’d like to enter those days in a csv file and import them via a service call.
Ideally, I need two services:
This way I could import all the events, clear the entire year, and reimport events (when I make a mistake or the company sends an update).
You can sort of already do this.
When you create a local calendar, it stores the data in an ics file, in the .storage directory.
You would have to convert your events to ICS, but you can add them to that ics file, reload the calendar integration, et voila – calendar events.
a quick google suggets there are plenty of csv → ics tools around, which would make it easier than manually curating those events.
if you can write a script it would be pretty easy to put something together that does it for you.
FYI: with (some) pdf viewers you can select the information and paste that for example in excel (or any other spreadsheet program) which in turn might make the process easier to get your trash dates into a calendar.
I guess I have to write a pull request for the documentation but I have implemented this feature and submitted a pull request here, in case any of you wants to review my code:
Testing and feedback is much appreciated
Sadly the PDF files that we get don’t look too good.

I’ve contacted the company multiple times and finally, they replied that this is the only format they provide and won’t share any other format.
That’s a pity.
I was just trying to help/inspire to prevent monkey work which is so not 21st century.
Over here, we get an ics file which I import in my mail program and from there synchronize with Nextcloud which is integrated in HA.
Lucky you 
I’m happy that my local company isn’t sending telegrams 
I’ve tried several times, and I’ve sent emails to every address I could find. I even offered to create API for them, but all I got was the answer “No, because no”.
Thankfully the PDF has a table with the same structure, so I was able to create a parser.
Now, I must wait for Add read-only calendar from url by zeehio · Pull Request #126862 · home-assistant/core · GitHub, to have a fully working automated calendar.
Hello everyone,
does anyone know how to delete ICS calendars imported into the local calendar?
In other words, I have the problem that I have an imported ICS calendar that cannot be found as local_calendar.xyz.ics in the .storage directory.
UPDATE: Found out for myself. The affected calendar comes from the custom integration Waste Collection Schedule. I was just no longer aware of it.
Maybe the new update has delivered:
So long
