renpho-api 0.1.0

Unofficial Python client for the Renpho Health API — pull body composition data from Renpho smart scales.

renpho

Unofficial Python client for the Renpho Health API. Pull body composition measurements from Renpho smart scales programmatically.

Based on reverse-engineering from RenphoGarminSync-CLI.

Installation

pip install .

For .env file support (recommended for CLI usage):

pip install ".[dotenv]"

CLI Usage

1. Create a .env file (or export the variables):

RENPHO_EMAIL=[e-mail]
RENPHO_PASSWORD=your_plain_text_password

2. Run the CLI:

renpho

This will log in, discover your scales, fetch all measurements, print the 5 most recent, and save everything to renpho_data/ as JSON and CSV.

Environment variables

Variable	Required	Description
RENPHO_EMAIL	Yes	Your Renpho account email
RENPHO_PASSWORD	Yes	Your Renpho account password
RENPHO_DEBUG	No	Set to 1 to print API request/response details
RENPHO_OUTPUT_DIR	No	Output directory (default: renpho_data)

Library Usage

from renpho import RenphoClient

client = RenphoClient("[e-mail]", "password")
client.login()

# Fetch all measurements in one call
measurements = client.get_all_measurements()

for m in measurements:
    print(m["weight"], m.get("bodyfat"), m.get("muscle"))

Step-by-step control

from renpho import RenphoClient, save_json, save_csv

client = RenphoClient("[e-mail]", "password")
client.login()

# Get device/scale info
device_info = client.get_device_info()
scales = device_info["scale"]

# Fetch from a specific scale table
table = scales[0]
measurements = client.get_measurements(
    table_name=table["tableName"],
    user_id=client.user_id,
    total_count=table["count"],
)

# Export
save_json(measurements, "my_data.json")
save_csv(measurements, "my_data.csv")

Error handling

from renpho import RenphoClient, RenphoAPIError

client = RenphoClient("[e-mail]", "wrong_password")
try:
    client.login()
except RenphoAPIError as e:
    print(f"API error: {e}")
