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+
- Your past data is imported, working backwards 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
- Past data cannot be imported, because Basic does not share history with apps. Your archive builds forward from the day you connect.
- 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 is yours
Every reading is stored in Pro Weather's own database, whatever your WeatherLink plan. Nothing is deleted if your Pro Weather subscription lapses (archiving pauses until you resume), only if you delete the site. You can export the whole archive as CSV at any time.
Your WeatherLink quota
Pro Weather polls each station about 70 times an hour, never once per visitor, well inside the 1,000 calls per hour WeatherLink allows. A Basic station is polled less often, since it only publishes a new record every 15 minutes.
Which plan should I use?
- Basic is enough for a complete, live site. History builds up from the day you connect.
- Pro or Pro+ if you want your past history imported from day one, or finer resolution.
