CPAP PrismaAPP Log Skill

Automatically fetches CPAP therapy data from the Löwenstein PrismaAPP backend and writes a structured daily Obsidian note.

When Triggered

• User says: "CPAP log", "CPAP data", "write sleep therapy", "prisma log", "CPAP today/yesterday/[date]"
• Daily cron job fires (configurable)
• User requests a historical backfill

Prerequisites

• Account at my.prismacloud.com with a linked Löwenstein CPAP device
• Device synced via the PrismaAPP mobile app (data must be uploaded to the server)
• Credentials stored in skills/cpap-prisma-app/config.json

Execution

Step 1: Run the Python script

Yesterday (default):

python3 ~/.openclaw/workspace/skills/cpap-prisma-app/scripts/fetch-cpap.py

Specific date:

python3 ~/.openclaw/workspace/skills/cpap-prisma-app/scripts/fetch-cpap.py 2026-04-06

Backfill all data since first sync:

python3 ~/.openclaw/workspace/skills/cpap-prisma-app/scripts/fetch-cpap.py --all

Backfill from a specific date:

python3 ~/.openclaw/workspace/skills/cpap-prisma-app/scripts/fetch-cpap.py --from=2026-03-01

Step 2: Confirm output

The script prints a summary and writes the note to:

<vault_path>/<log_dir>/YYYY-MM-DD.md

Output Format (Note)

The generated note contains:

• Frontmatter: date, weekday, tags (including quality tag), source, created timestamp
• Summary table: sleep duration, deep sleep, AHI, leakage, snoring %, mask fit %, therapy mode/pressure
• Overall quality rating (🟢/🟡/🟠/🔴) derived from AHI, leakage, and deep sleep scores
• Detailed sections: Sleep, CPAP Therapy, Snoring & Mask
• Navigation links to the previous and next logged day

All text is fully localised — see the locales/ folder.

Quality Mapping

AHI Reference

Troubleshooting

No data for date:

• Check whether the device was used that night
• Open PrismaAPP on the phone to trigger a Bluetooth sync
• Data only appears after the device has synced with the app

Login error:

• Verify credentials in config.json
• Check that my.prismacloud.com is reachable
• A password change in PrismaAPP requires a config.json update

Wrong API responses (HTML instead of JSON):

• Always use my.prismacloud.com as the API base
• bucharest.prismacloud.cc is the web SPA only — it returns HTML for all paths
