Google Calendar

Google Calendars are natively supported. You can directly connect to and sync with a Google account. The configuration is done via the companion app. 

Outlook Calendar (Microsoft) 

You can use the "publish" feature in outlook to create an iCalendar url for your outlook calendar. With this link, you can then add the Outlook calendar to the E-Paper Calendar via the companion app.

The URL of a "public" Outlook calendar is secret and hard to guess, but there may be situations where this isn't as safe as a password-protected link. So you will have to use this option at your own discretion. 

Instructions can be found here. 

iCloud Calendar (Apple) 

You can share any iCloud calendar by generating an ICS link. Check out this iPhone User Guide and scroll down to "Share a read-only calendar with anyone".

With this link, you can then add the calendar to the E-Paper Calendar via the companion app.  

The URL of the ICS link is hard to guess, but there may be situations where this isn't as safe as a password-protected link. 

 

Hey.com Calendar

You can create a sharable .ics link for your hey.com calendar, which you can then copy and paste into the companion app of the Invisible Smart Display. 

 

Anything Supporting CalDAV or iCalendar

Smaller digital calendar providers, such as for example Fastmail, typically offer CalDAV or iCalendar subscription urls. ( iCalendar urls sometimes end with the `.ics` file extension. CalDAV urls typically have no file extension. ) With the companion app, you can easily configure your E-Paper Calendar to sync calendars and events from any CalDAV or iCalendar URL on the internet.
