weathercloud

Unofficial, fully-typed Python client for Weathercloud. Read live conditions, station metadata, history, and forecasts from any public station — no account, no API key (recommended). Authentication is optional and only required if you want to access private indoor sensors (like inside temperature, humidity, and heat index) of a station you own.

⚠️ Reverse-engineered from the public web app. Not affiliated with or endorsed by Weathercloud, and the upstream endpoints may change without notice.

✨ Highlights

• 🌡️ Typed results — get_current_conditions() returns a CurrentConditions dataclass, not a bag of stringly-typed JSON.
• 🧱 Raw access too — every endpoint also has a dict-returning method when you need the full payload.
• 🧯 One exception to catch — every failure (network, HTTP, bad JSON) raises WeathercloudError.
• 🧪 Tested & type-checked — ships py.typed, runs on Python 3.10–3.13.

📦 Installation

pip install weathercloud

🚀 Quick start

from weathercloud import WeathercloudClient

# Public data requires no login:
with WeathercloudClient() as client:
    cond = client.get_current_conditions("5726468552")

print(cond.temperature)   # 22.8
print(cond.humidity)      # 62

# Pass your credentials to fetch private indoor sensors:
with WeathercloudClient(username="my_user", password="my_password") as client:
    cond = client.get_current_conditions("5726468552")

print(cond.inside_temperature)  # 21.5 (None if not logged in)
print(cond.inside_humidity)     # 55

The client owns a requests.Session, so use it as a context manager (or call client.close()) to release connections. You can also tune the request timeout:

client = WeathercloudClient(timeout=30)   # seconds; default is 10
# or with both credentials and timeout:
client = WeathercloudClient(username="user", password="pass", timeout=15)

📖 API

get_current_conditions(device_id) → CurrentConditions

Live sensor readings as a typed dataclass — the one you'll call most. Stations only report the sensors they actually have, so every field is optional: a reading the station doesn't provide comes back as None rather than raising.

get_station_info(device_id, scrape_name=True) → StationInfo

Station metadata. The name isn't exposed by any JSON endpoint, so it's scraped from the page <title> (one extra request). Pass scrape_name=False to skip it and use the device_id as the name instead.

info = client.get_station_info("5726468552")
info.name                   # "Ginometeo"
info.city                   # "Ingelmunster"
info.altitude               # "18.0"  (metres, as string)
info.status                 # "online" | "recently_online" | "offline" | "unknown"
info.seconds_since_update   # int
info.account_type           # 0 = free, >0 = premium

get_device_stats(device_id) → dict

Current readings plus day / month / year min–max. Each value is a [unix_timestamp, value] pair, keyed as {sensor}_{period}_{type}.

stats = client.get_device_stats("5726468552")
stats["temp_day_max"]       # [1748358122, 30.9]
stats["rain_month_total"]   # [1748358122, 12.4]

get_evolution(device_id, variable, period="day") → dict

Hourly history for a single sensor. period is "day", "week", "month", or "year".

from weathercloud import VariableCode

evo = client.get_evolution("5726468552", VariableCode.TEMPERATURE, "week")

Available codes: TEMPERATURE, HUMIDITY, DEW_POINT, PRESSURE, WIND_SPEED, WIND_DIRECTION, WIND_GUST, RAIN, RAIN_RATE, SOLAR_RADIATION, UV_INDEX.

get_forecast(device_id) → dict

6-day WMO daily forecast for the station's location.

get_nearby_stations(lat, lon, distance_km=5) → dict

Stations within a radius of a coordinate. ⚠️ Sensor values inside each result are ×10 integers — divide by 10 (e.g. temp: 281 → 28.1 °C).

Other raw methods

client.get_device_values(device_id)    # same data as get_current_conditions, raw
client.get_device_info(device_id)       # metadata + current values as strings
client.get_wind_rose(device_id)         # wind direction distribution
client.get_update_status(device_id)     # seconds since last update
client.get_owner_profile(device_id)     # observer name, hardware brand/model
client.get_station_name(device_id)      # scrape the station name only

🧯 Error handling

Every method raises WeathercloudError on failure — network error, HTTP error, non-JSON body, or an unexpected response shape. Catch the one type and you're covered.

from weathercloud import WeathercloudClient, WeathercloudError

try:
    cond = client.get_current_conditions(device_id)
except WeathercloudError as exc:
    ...  # set unavailable, log it, retry — your call

🔎 Finding a device ID

It's the number at the end of the station URL:

app.weathercloud.net/d5726468552  →  device_id = "5726468552"

METAR (airport) stations use ICAO codes (EBBR, EGLL, …) and work on most device/* endpoints — just swap the prefix to metar/*.

💡 Notes

• 🔓 No authentication required for public endpoints (recommended). Supply credentials only if you need to fetch private inside sensors of a station you own.
• ⏱️ Poll at most every 10 minutes — that's how often free stations update.
• 🧭 Based on the reverse-engineered OpenAPI spec in this repo.

🛠️ Development

git clone https://github.com/MauroDruwel/Weathercloud
cd Weathercloud
python -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"

ruff check .      # lint
mypy              # type-check
pytest            # tests
python -m build   # build sdist + wheel

CI runs the linter, type checker, and the test matrix (Python 3.10–3.13) on every push and pull request.
