Project 6: Your own dashboard

Goal: one page with your steps, sleep, resting heart rate and HRV over the last months, every device together, and a training chart on it that you added yourself.

Time: 20 minutes. Level: some Python. Needs: project 1.

1. Make the pageCopy Anchor Link

python3 recipes/dashboard.py

wrote health-dashboard.html: open it in a browser

It is a single HTML file, with no script and nothing loaded from the internet. Bars and dots are days, the line is the 7 day average, and hovering a day shows its value. It follows your light or dark mode.

2. Add a training chartCopy Anchor Link

Make your own copy first, so an update of the repository never overwrites your changes:

cp recipes/dashboard.py my-dashboard.py

Open my-dashboard.py and find def main():. Just above the line that starts with apps = sorted(, add the minutes of training per day:

    training = defaultdict(float)
    for w in records("workouts", start=start.isoformat()):
        training[date.fromisoformat(w["start_date"][:10])] += (w["duration_s"] or 0) / 60

Then add one line to the list of charts, after the heart rate variability one:

        chart("Training", "min", training, start, a.days, True, "{:.0f}"),

python3 my-dashboard.py --days 60

Open health-dashboard.html again: a fifth chart shows your training as daily bars, under the four others. The chart() function does the drawing; you only gave it a name, a unit, a value per day and True for bars (False draws dots).

• Another daily figure. kcal, _ = daily("active_kcal", start) gives a value per day from the app that reports it most, ready for chart(); readiness_score and recovery_score work the same for a ring or a band. The fields are listed under DailySummary.
• A year. --days 365 --out year.html is a good page to look at in January.
• Every morning. Run it from cron and write the file into a folder your home server publishes, so the page on your phone is always today's.

The file holds your health data: share a screenshot rather than the page itself, or crop the numbers out.
