Just for an example for those who do have a weather station close enough.

Switch vIsCloudy "Cloud Conditions" <iscloudy> (gChart)

iscloudy is a custom icon I downloaded. gChart makes this Item be persisted for charting. See Design Pattern: Group Based Persistence.

I’ll not show the Weather Items but you can find them all here: Comprehensive Wunderground using HTTP Binding Example

rule "Is it cloudy outside?"
when
        Item vWeather_Conditions changed
then
        logInfo(logName, "New weather conditions: " + vWeather_Conditions.state.toString)

        val isCloudy = transform("MAP", "weather.map", vWeather_Conditions.state.toString)
        val newState = if(isCloudy === null || isCloudy == "false") OFF else ON

        if(newState != vIsCloudy.state) logInfo(logName, "Setting isCloudy to " + newState.toString)

        vIsCloudy.postUpdate(newState)
end

weather.map has a mapping from all the conditions that Wunderground supports to true or false to indicate whether the condition indicates it is cloudy.
