# OpenMeteo
|
|
|
|
This plugin allows to get current weather and solar irradiance data from [Open-Meteo](https://open-meteo.com), including plane-of-array irradiance (GTI) for photovoltaic surfaces and satellite-observed clear-sky data.
|
|
|
|
## Usage
|
|
|
|
The data is refreshed every 15 minutes automatically, and can also be refreshed manually.
|
|
|
|
A **site** is added by entering its latitude and longitude (no discovery). It provides the shared weather and solar data for the location, including a satellite-observed GHI and clear-sky index.
|
|
|
|
One or more **PV planes** can be added as children of a site. Each plane has its own tilt, azimuth and peak power, and reports the global tilted irradiance (GTI) for that orientation. Multiple orientations are handled by adding multiple planes.
|
|
|
|
> Note: the azimuth is entered in geographic convention (180 = South, 90 = East, 270 = West).
|
|
|
|
By default the plugin queries the public Open-Meteo API. For commercial deployments, the `Base URL` and `Base URL (satellite radiation)` plugin settings can be pointed to a self-hosted Open-Meteo instance (the public API is for non-commercial use only).
