PythonでFitbit(2)

未分類

本ページの概要
Fitbitで測定した24時間心拍，24時間歩数，睡眠時間を，1週間分取得する方法を学習します。

PythonでFitbitデータを取得する
下記のプログラム「getWeekHR.py」をエディタで開発ディレクトリに作成し，USER_ID ，CLIENT_SECRET をセットします。さらにプログラム末尾の，
today=date(2025, 10, 15)
for var in range(0, 7):
部分をセットします。上記は「2025/10/15から遡って7日間のデータを取得する」という処理になります。
ターミナル上で，
python getWeekHR.py
と入力し，実行する。正常に動作すると，
「23QTVF_HR.csv」のようなファイルが開発ディレクトリに作成される。「getWeekSLEEP.py」，「getWeekSTEP.py」も同様に使用する。
