Import/Sync Calendar Events

[N1c093]

Hello all,

I would like to share my Blueprint with you.
With this Blueprint you can import/sync calendar events from one calendar to another.

For example you can import calendar events from your google calendar to another calendar.

Prerequisites
Have at least two calendar configured in Home Assistant. One calendar must have write access.

blueprint:
  name: Import Calendar Events

  domain: automation

  input:
    calendar_source:

          domain:
            - calendar
