WeatherLink plans & your data
How Pro Weather works on each Davis WeatherLink plan, and how far back your history can be imported.
Pro Weather works on every WeatherLink plan, including the free Basic plan. All it needs is a WeatherLink v2 API key, which every plan can generate. See Connect your WeatherLink station.
Two different Pro plans
WeatherLink Pro and Pro+ are Davis subscriptions, paid to Davis. Pro Weather Pro is this service's plan, paid to us. They are independent: a free WeatherLink Basic station can run on Pro Weather Pro.
What each plan allows
| WeatherLink plan | History available to apps | Record interval |
|---|---|---|
| Basic (free) | No, current conditions only | 15 minutes |
| Pro (paid) | Yes, the full archive | down to 5 minutes |
| Pro+ (paid) | Yes, the full archive | down to 1 minute |
Davis sets these plans and can change them. Check weatherlink.com for current details.
On WeatherLink Pro or Pro+
Choose these if you want your past history from day one, or finer resolution.
- Your past data is imported, back as far as your WeatherLink records go, so charts, records and the almanac start out full.
- New records reach your public site within about a minute of WeatherLink publishing them. Charts and history follow every 5 minutes.
- Your archive keeps your plan's full resolution, down to every minute on Pro+.
On WeatherLink Basic
Enough for a complete, live site; history builds up from the day you connect.
- Past data cannot be imported: Basic does not share history with apps.
- Live conditions update every 15 minutes, the Basic record interval.
- To bring older readings in anyway, import a weewx, CumulusMX or CSV history file.
The History card on your site's Overview shows which of the two is happening, and whether an import is still running. See Where your archive stands.
Your archive and your quota
Every reading is stored in Pro Weather's own database, whatever your WeatherLink plan, and kept until you delete the site. You can export it as CSV at any time.
Pro Weather polls each station about 70 times an hour (a Basic station less often), never once per visitor, well inside the 1,000 calls per hour WeatherLink allows.
