The story

It started as a contraction tracker during labor — one button press logged a contraction, timestamped it, and pinged both our phones. It carried us through 700+ contractions over two weeks.

When our son arrived, the contraction tracker was retired the same day and reborn as a baby tracker: feeds, diapers, sleep, baths, medicine, tummy time, weight and pumping. Keeping the same low-friction, high‑WAF spirit, we 3D-printed a labeled button remote so nobody has to unlock a phone to log a diaper change at 3 am.

What it does

🍼

One-tap logging

17 event types across 8 categories — feed, pump, diaper, sleep, bath, medicine, tummy time, weight + notes.

📊

Live stats & journal

Last feed/diaper, totals today, sleep time, and a running journal — in a one-tap Ingress web UI.

🏠

Native HA entities

Sensors, a “sleeping” binary sensor, and a button per action appear automatically via MQTT discovery.

🎛️

Physical remote

A 3D-printed ESP32-C3 keypad publishes each press over MQTT — log without a screen.

⏰

Pump reminders

Independent per-side timers ping your phone when it's time to pump again.
