New parents don't have a free hand, let alone patience for an app at 3 a.m. The whole point of tracking feeds, diapers and sleep is the data — but only if logging it is effortless. So we made it one tap.
The software
A small Home Assistant add-on (FastAPI + SQLite) gives you a clean web UI: one tap per feed, pump, diaper or sleep event. It publishes everything as native Home Assistant entities over MQTT, so the data lives in HA alongside everything else — dashboards, history, statistics, automations ("if no feed logged in 4 hours, remind me").
The hardware
Tapping a phone still means finding the phone. So we built a 3D-printed button remote: an ESP32 with a physical keypad and a little OLED that shows the last event and time-since. Slap it on the nursery wall — tap the button, done, no screen unlock, no app.
- Native HA entities over MQTT (no fragile YAML)
- 3D-printed enclosure + OLED status
- Runs fully local — your baby's data never leaves the house
Get it
The add-on and the hardware/firmware are open source. Or — because the last thing a new parent wants is a soldering project — order the button remote pre-built and ready to pair.
