room_cal

room-cal

A self-hosted calendar management tool for short-term rental hosts. It syncs pricing, availability, reservations, and discounts between a local CalDAV calendar and external booking platforms (Airbnb, Booking.com). A FastAPI HTTP server exposes the data to a Vue-based web calendar, and a FastMCP server exposes health checks to AI assistants.

Installation

See docker/README.md for container-based deployment (recommended for production).

For local development:

# Install dependencies (requires uv)
uv sync --group dev

# Activate git hooks
git config core.hooksPath .githooks

---

Configuration

Start from room_cal/config.json (the bundled defaults) and place an override at ~/.local/room_cal/config.json (or $ROOM_CAL_DATA_HOME/config.json). Keys are deep-merged — you only need to include what you want to change.

room_cal/config-all.json is a generated file that shows every available config key with its default value. It is kept up to date automatically by the pre-commit hook and is the canonical reference for what can be configured.

uv run room-cal fetch-user-cal     2026-07-01 2026-07-31
uv run room-cal push-busy          2026-07-01 2026-07-31

# Local-only workflows (no service API calls)
uv run room-cal local-sync         2026-07-01 2026-07-31   # feeds + rules + fill + busy
uv run room-cal local-refresh      2026-07-01 2026-07-31   # rewrite all local Room calendar events

API server

uv run room-api

Serves the web calendar at http://localhost:8000 and exposes REST endpoints for all sync operations.

Refreshing credentials (refresh-creds)

Session cookies for Airbnb and Booking.com are obtained via a Playwright browser session and must be periodically refreshed.

uv run refresh-creds [--output=file|stdout|api]

Three output modes are available:

Mode	Behaviour
file (default)	Writes credentials to airbnb.env and booking.env in $ROOM_CAL_DATA_HOME
stdout	Prints credentials to stdout — useful for piping or inspection
api	POSTs credentials directly to a running room-api instance

The api mode requires api_url to be set in your config.json:

{
  "api_url": "https://your-room-cal-instance.example.com"
}

Web calendar (calendar.html)

The web calendar provides a month view of all pricing and availability data. Key features:

• Month navigation — prev/next buttons to move between months
• Day detail panel — click any day to see its price, discount, reservation, and closed status for each service; prices and discounts are editable inline
• Sync mode — toggle the sync bar on to see which days have mismatches between local CalDAV and remote platforms; a badge shows the total number of days with issues
• Per-day sync controls — push (↑) or fetch (↓) prices, closed status, discounts, reservations, and user calendar data for individual days
• Per-month sync controls — bulk push or fetch prices and closed status for the entire visible month; a Fill button creates default local prices for any missing dates
• iCal feed blocks — external feed closures (e.g. a fire safety calendar) are shown and can be fetched per day
• Rule discounts — pipeline-generated discounts are shown alongside manual discounts; mismatches between the rule output and what's on the calendar are surfaced
• Health indicator — a header button polls GET /health and shows green/amber/red based on CalDAV connectivity and service credential status

Developer notes

Git hooks

The repo includes a pre-commit hook that regenerates room_cal/config-all.json automatically on every commit. After cloning, activate it with:

git config core.hooksPath .githooks

To regenerate the file manually:

uv run python scripts/gen_example_config.py > room_cal/config-all.json

Tests

Store tests run without any live server. Service API and CalDAV tests require live credentials:

uv run python -m pytest tests/
