WeatherFlow Tempest API & Developer Platform

https://weatherflow.github.io/Tempest/api/

Most third-party Tempest apps and integrations are designed for the personal use by a single Tempest System owner. 

To start using the REST or WS API, all you need is an access token. Your app or integration must ensure that the user viewing the station data is the owner of that station by authenticating the user’s account. There are two options for authentication: Oauth or the Personal Access Token.

To create a WeatherFlow login:
Download the Tempest app from the app stores.
