# Connect your WeatherLink station

> Generate a WeatherLink v2 API key so live data flows into your site.

Pro Weather reads your station's data directly from the **WeatherLink v2 API**,
using an API key you generate yourself. There's nothing to install and no data
feed to configure by hand. Paste the key once and we discover every station and
sensor on your account automatically.

No Davis station? Ecowitt gateways and most other hardware can feed your site
too - see [Connect other hardware](https://pro-weather.com/docs/getting-started/connect-hardware).

## Before you start

Make sure your Davis station is already **online in WeatherLink** and reporting
current conditions. If you can see live data at weatherlink.com, you're ready.

## 1. Generate your WeatherLink v2 API key

You'll create a free **API Key** and **API Secret** in your own WeatherLink
account:

1. Sign in to your WeatherLink account at **weatherlink.com/account**.
2. Open the **WeatherLink v2 API** section (it may be labelled "API Keys").
3. **Generate a new v2 key**. WeatherLink shows you an **API Key** and an
   **API Secret**. Copy both.

  Pro Weather needs a **WeatherLink v2** API key and secret, not a v1 key and not
  your weatherlink.com password. Generating a key is free and doesn't affect how
  you use WeatherLink.

## 2. Connect it to your site

1. In your Pro Weather dashboard, open your site and go to **Connection**.
2. Paste your **WeatherLink API Key** and **WeatherLink API Secret** into the
   form.
3. Choose **Connect WeatherLink**.

Your secret is **encrypted before it's stored** and is never sent back to the
browser. We use it only to fetch your station's data.

## What happens next

As soon as you connect, Pro Weather **auto-discovers** every station and sensor
on your account. There's no station picker to fill in. Each discovered station is
listed on the Connection page with its name, ID, location and sensors.

Discovery also picks up your station's **coordinates and time zone** from
WeatherLink - they power the [forecast](https://pro-weather.com/docs/features/forecast), astronomy,
severe-weather warnings and day boundaries, with nothing to configure. And if
your station is in the **United States**, your site
[starts in imperial units](https://pro-weather.com/docs/customizing/units-language#us-stations-default-to-imperial)
automatically.

If your account has **more than one station**, you can choose which one your site
shows under **Settings → Stations to display**.

Added a new sensor or station in WeatherLink later? Open **Connection** again and
choose **Reconnect & rediscover** to pick it up.

## What gets published

Once connected, your site automatically shows the readings your station reports,
which may include:

- Temperature, feels-like, humidity and dew point
- Wind speed, gusts and direction
- Rainfall and rain rate
- Barometric pressure
- Solar radiation and UV index
- Air quality, if you have an **[AirLink](https://pro-weather.com/docs/features/air-quality)** sensor

History and charts fill in over time as your station keeps reporting. Pro Weather
fetches your data once every few minutes and caches it, so visitors never hit the
WeatherLink API directly. Even a busy site stays light on your quota.

How much history you get depends on your WeatherLink plan: on **Pro/Pro+** Pro
Weather can import your past data, while on the free **Basic** plan it builds
history forward from the day you connect. See
[WeatherLink plans & your data](https://pro-weather.com/docs/weatherlink-plans) for the full picture.

  If readings look missing or stale, confirm the station is still online in
  WeatherLink, that the v2 key and secret are correct, and that you selected the
  right station under Settings. New stations can take a few minutes to appear
  after they first report.
