This repo contains a Val Town-ready script that:

• queries a Notion database for the last 7 days of blood sugar entries (UTC date range)
• computes simple stats (avg/min/max, count, missing entries, expected 2 per day)
• emails a weekly rollup to your Val Town account (free tier friendly)

Think of this as a simple weekly helper:

• You write down blood sugar readings in Notion.
• Once a week, the script looks at the last 7 days of entries.
• It adds up your numbers to give you a quick summary.
• Then it emails that summary to you automatically.

Even though this feels simple, it uses a few classic CS ideas:

• Data modeling: you define what a “reading” is (date, time, value).
• Filtering: you only look at a specific window of time (last 7 days).
• Aggregation: you summarize many values into a few stats (avg/min/max).
• Automation: a scheduled job runs the same steps every week.

If you can build or understand this, you’re already practicing real CS thinking—just without the scary jargon.

Create a new database in Notion (table view is easiest) with these properties:

• Entry (Title)
• Created Time (Created time) or Created Time (Text)
• Measurement Date (Date) (e.g., January 13, 2026)
• Blood Sugar Level (Number)
• Notes (Text) (optional)

You can name the database anything (e.g., "Blood Sugar Log").

1. Go to https://www.notion.so/my-integrations and create a new integration.
2. Copy the Internal Integration Token.
3. Open your database in Notion, click Share, and invite the integration.

Open the database in the browser and copy the 32‑character ID in the URL.

Create a new Val in Val Town and paste notion_weekly_report.ts.

Add these secrets in Val Town (Settings → Secrets):

• NOTION_TOKEN
• NOTION_DATABASE_ID
• REPORT_FROM_EMAIL (optional, must be your_username.valname@valtown.email)
• REPORT_FROM_NAME (optional)
• REPORT_REPLY_TO (optional)
• REPORT_TO (optional; only set on Val Town Pro)

Free tier note: REPORT_TO must be omitted unless you are on Val Town Pro.

In Val Town, schedule the Val to run weekly at 9:30am on Tuesdays (EST).

Suggested cron (set Val Town timezone to EST):

30 9 * * 2

Cron is a simple way to say “run this on a schedule.” It has five fields:

minute hour day-of-month month day-of-week

So 30 9 * * 2 means:

• minute = 30
• hour = 9
• day-of-month = * (every day of the month)
• month = * (every month)
• day-of-week = 2 (Tuesday)

In other words: every Tuesday at 9:30am.

• Adjust the stats, date range, or email formatting in notion_weekly_report.ts.
• If you prefer different property names, update them in the script.
