| 3 | | The Weather plugin is a [http://wiki.micasaverde.com/index.php/Luup_Plugins Luup component] that captures, displays, and periodically updates Temperature and Humidity data based upon Vera's current [http://wiki.micasaverde.com/index.php/Location Location]. |

| 5 | | = How does it work = |
| 6 | | The plugin uses the Latitude/Longitude values configured in Vera's [http://wiki.micasaverde.com/index.php/Location Location] settings, and data provided by the ''Unofficial'' Google Weather service, to retrieve: |
| 7 | | |
| 8 | | * Temperature - The Current temperature |
| 9 | | * Low Temperature - The ''estimated'' low temperature |
| 10 | | * High Temperature - The ''estimated'' high temperature |
| 11 | | * Humidity - The ''estimated'' humidity |
| 12 | | |
| 13 | | Each of these values is presented as a Child Device of the Weather plugin, implementing the respective [http://wiki.micasaverde.com/index.php/Luup_UPNP_Files UPnP Service]. They're all set to be visually ''grouped'' in the UI/Presentation. |
| 14 | | |
| 15 | | Behind the scenes, the plugin uses Vera's ''Latitude'' and ''Longitude'' values, derived from the User-specified [http://wiki.micasaverde.com/index.php/Location Location] settings, to help form a URL to the Google Weather API. This URL call looks like: |
| 16 | | |
| 17 | | http://www.google.com/ig/api?weather=,,,40980465,-72212690 |
| 18 | | |
| 19 | | The plugin selects elements from the XML output, and translates them into values that are set upon the respective Child Devices. |
| 20 | | |
| 21 | | The Weather plugin retrieves the Weather data at startup, and again every 30 minutes after that. |
