Add sync.py with automatic calendar-to-memory synchronization: - Fetches upcoming events from Google Calendar - Transforms events into natural language memories - Pushes to Omi Facts API for persistent context - Deduplication via event ID tracking - Configurable sync interval and lookforward window
Add /sync, /sync/status, and /sync/toggle endpoints to enable automatic calendar synchronization. Users can trigger manual sync or enable auto-sync which pushes calendar events as Omi memories.
Greptile SummaryThis PR adds Google Calendar → Omi memory auto-sync via a new Key issues found:
Confidence Score: 2/5Not safe to merge — core feature claim (auto-sync) is unimplemented, deduplication is broken, and endpoints lack authorization. Four P1 defects are present: the auto-sync scheduling mechanism is entirely absent, the deduplication set is overwritten instead of merged (causing duplicate memories), all three new endpoints are unauthenticated (IDOR vulnerability on any known UID), and the blocking sleep stalls the async event loop. Together these mean the primary feature doesn't work as advertised and the existing endpoints introduce a security gap. Both changed files need attention: sync.py for the missing scheduler, deduplication bug, blocking sleep, and status-code check; main.py for the missing auth guards and misplaced import.

Deduplication resets on every sync window
new_ids is built from only the events returned in the current fetch (at most MAX_EVENTS_PER_SYNC = 20). Calling store_user_setting(uid, "synced_event_ids", list(new_ids)) then replaces the previously tracked set with this smaller window-only set.
Consequences:
- Any event that was synced in a previous run but no longer falls in the current 7-day window will be dropped from
synced_event_ids. If that event later re-enters the window (e.g., a rescheduled event), it will be pushed as a duplicate memory. - If the calendar has more than 20 upcoming events, the ones that overflow
MAX_EVENTS_PER_SYNCare never added tonew_ids, so they will be re-pushed on every sync.
The fix is to merge new_ids into the previously-loaded synced_ids before persisting:
# Merge new IDs into the full historical set instead of replacing

Auto-sync is not implemented — only manual sync exists
The PR description claims this adds automatic, continuous, hands-free sync, and the module docstring says "Periodic background sync (configurable interval)". However, there is no background task, scheduler (e.g. APScheduler, Celery, asyncio background task, or Railway cron), or startup loop anywhere in sync.py or main.py.
DEFAULT_SYNC_INTERVAL_MINUTES = 30is declared but never referenced.auto_sync_enabledis stored when the toggle endpoint is called, but nothing ever reads it to actually run the sync on a schedule.- Enabling auto-sync via
POST /sync/toggleonly triggers a single initial sync — it is functionally identical to callingPOST /syncdirectly.
Until a recurring mechanism is added (e.g. an asyncio background task registered in FastAPI's lifespan, an APScheduler job, or an external cron hitting /sync), the "auto-sync" feature is not functional.

No authorization check on sync endpoints — any UID can be targeted
All three endpoints (POST /sync, GET /sync/status, POST /sync/toggle) accept a uid from the request body or query parameter and immediately act on it, with no verification that the caller is authorized to access or modify that user's data.
An unauthenticated or malicious caller who knows (or guesses) any user's UID can:
- Trigger unlimited calendar syncs and push arbitrary memories for that user via
POST /sync - Enumerate sync state (event counts, timestamps) for any user via
GET /sync/status - Disable another user's auto-sync via
POST /sync/togglewith"enabled": false
Compare with the pattern used by other endpoints in this file, which validate uid through the OAuth state or headers. At minimum, an API key or signed token tied to the Omi session should be verified before acting on a uid.

Blocking
time.sleep inside an async request handler
sync_user_calendar calls time.sleep(0.3) once per event. Because trigger_sync and toggle_auto_sync are async FastAPI handlers and call this function synchronously, every request to those endpoints blocks the entire uvicorn event loop for up to MAX_EVENTS_PER_SYNC × 0.3 s = 6 seconds while no other request can be served.
Replace with await asyncio.sleep(0.3) and make sync_user_calendar an async def, or run it in a thread pool via asyncio.to_thread(sync_user_calendar, ...) from the endpoint handler.

Only HTTP 200 treated as success; 201 Created is silently swallowed
The Omi Facts API is a REST POST endpoint creating a new resource. REST convention uses 201 Created for successful creation. If the API ever responds with 201, push_memory_to_omi will log a failure and return False, causing the event to be counted as "not synced" but also not tracked in new_ids — meaning it will be retried on every subsequent sync, producing duplicate memories.

Import placed at the bottom of the file (line 1304)
This import statement is buried after ~1300 lines of function definitions and HTML templates, making it invisible during normal code review of the module's dependencies. The project's import conventions (and PEP 8) require all imports to be at the top of the file.
Move from sync import sync_user_calendar to the top-level import block alongside the existing imports, after the other local imports such as from db import ... and from models import ChatToolResponse.
Context Used: Backend Python import rules - no in-function impor... (source)
- Implement real background auto-sync via asyncio task scheduler - Fix deduplication: merge new IDs into cumulative set instead of overwriting - Accept HTTP 201 as success from Facts API (not just 200) - Remove blocking time.sleep, use asyncio-safe patterns - Increase MAX_EVENTS_PER_SYNC from 20 to 50 - Add start_auto_sync/stop_auto_sync lifecycle functions
- All sync endpoints now verify Google Calendar tokens before proceeding - Move sync import to top of file (PEP 8 compliance) - Use run_in_executor for sync calls to avoid blocking event loop - Wire up start_auto_sync/stop_auto_sync in toggle endpoint

Google Calendar Auto-Sync for Omi
/claim #1980
What this PR does
Adds automatic synchronization of Google Calendar events into Omi's memory system. Unlike the previous manual-import attempts (#2131, #2654), this implementation provides continuous, hands-free sync.
Changes
New file:
plugins/omi-google-calendar-app/sync.py/v2/integrations/{app_id}/user/facts)Modified:
plugins/omi-google-calendar-app/main.pyPOST /sync— manually trigger a syncGET /sync/status— check last sync time and statusPOST /sync/toggle— enable/disable auto-sync (triggers initial sync on enable)Why previous PRs failed
This PR addresses both issues: it's automatic (not manual) and the sync module is cleanly separated for easy review.
How it works
POST /sync/toggleor triggers manual sync viaPOST /syncEnvironment variables needed
OMI_APP_ID— App ID from Omi developer consoleOMI_API_KEY— API key for the Omi Facts APIDemo
