OpenNoiseRep

Your Noise REP band's data, without the vendor app.

OpenNoiseRep is an open-source desktop app and menu-bar tool that reads heart rate, steps, HRV, sleep/rest and RRI data from the Noise REP band over BLE. It stores everything locally, needs no NoiseFit account, and exports CSV/JSON — with a live heart rate in the Mac menu bar. The Python package and command are still named noiserep. Screenshots use synthetic demo data.

Features

• Historical sync: device info, data index, heart-rate/activity series and pushed activity files.
• Desktop app: vitals, sleep, heart/stress, movement goals, charts and export.
• Day picker with calendar and previous/next day, plus 7-day, 30-day, all-data and custom ranges.
• Menu-bar heart rate: ♥ 72 worn, ♥ ~ off-wrist, ♥ — disconnected. Optional walk-away lock.
• RRI/HRV rest summaries: duration, average HR, RMSSD/SDNN/pNN50 and coverage.
• Steps, distance, active calories and active minutes.
• CSV/JSON export and offline .pklg decoding.

Install

python -m venv venv && . venv/bin/activate
pip install -e '.[ble,gui]'

Python 3.10+.

Use

noiserep sync                      # fetch history
noiserep gui                       # desktop app
noiserep menubar                   # live heart rate in the menu bar
noiserep sleep                     # last night's rest summary
noiserep workouts                  # workout files, when present
noiserep export --format csv --out all.csv
noiserep decode capture.pklg       # offline

The band accepts one BLE central at a time. Wake it (or put it on the charger) and turn the phone's Bluetooth off while syncing.

Further development

• Custom notification vibration: validate the buzz patterns and add triggers.
• Live HR: confirm the realtime command or start the optical sensor on demand.
• Sleep stages and score: fetch and decode a staged sleep file.
• Workout files: parse sport files when the band sends them.
• Temperature calibration for raw values such as 213.
• Packaging, signing, and Windows.
