# signalk-openweather-plugin
SignalK Plugin to inject forecast data from OpenWeather public weather service
-# Install & Use
+
+## Install & Use
Note: To use this plugin you need to request an apikey, ie. APPID on http://openweathermap.org/appid and start!
Install the plugin through the SignalK plugin interface. After installation you may want to 'Activate' it through the SignalK Plugin Config interface and enter your pre-requested apikey.
The plugin will inject several new SignalK-values, such as:
+
'environment.forecast.temperature'
'environment.forecast.humidity'
'environment.forecast.pressure'
-Forecast data is purely based on position - hence 'navigation.position'
needs to present. Data will be queried on position change and/or regularily on an hourly-basis (triggered by signalk-raspberry-pi-temperature-plugin). 'navigation.gnss.antennaAltitude'
(GPS altitude) is required if operated on non-sealevel altitude to compensate atmospheric pressure data to the appropriate elevation. Plugins like signalk-fixedstation could be used and the plugin will make calculations by adjusting the pressure accordingly. Default is altitude = 0 (sea level).It will take the plugin a few minutes before showing output data, as it will need to collect position information before requesting data from openweathermap.

'environment.outside.pressure'
like provided by RuuviTag severities could be more accurate and it's possible to set an alarm, i.e. via the Simple Notification-plugin.Simple output format is based on openweather-apis SMART JSON
