I created a plugin to sync tasks to my calendar using CalDAV. That solves tasks reminders notification problem and makes it easy to add tasks quickly to Obsidian.
It also allows me to use Remiders on Mac/Iphone and Tasks[.]org on Android.
Check on Github: josecoelho/obsidian-tasks-caldav please, give it a go, I would love some feedback.
(It’s not on obsidian store yet, so you need to install manually)

Features:
Multi-calendar support — sync different tags to different calendars and servers (tasks must have the tag on both sides — Obsidian #tag and CalDAV CATEGORIES)
- Bidirectional sync — push tasks to CalDAV servers and pull changes back
- Auto-sync — configurable interval (default: 5 minutes)
- Dry-run mode — preview what will sync before committing changes
- Conflict detection — manual resolution or auto-resolve with Obsidian wins
- Task notes — indented bullet points below a task round-trip as VTODO DESCRIPTION
- Recurrence —
RRULE round-trips between CalDAV and obsidian-tasks format
- Delete detection — three-way diff detects deletions on either side
- Reconciliation — automatically matches identical tasks when switching calendars or after lost sync data, preventing duplicates
