WXonline

This driver provides weather information and forecasts retrieved from the Yahoo! Weather service.

The information provided by this driver must be used in compliance with Yahoo!'s Terms of Use.

HSYCO Configuration

Add an WXONLINE I/O Server in the I/O Servers section of the Settings and set its parameters:

High Availability

• Shutdown when inactive: defaults to true.

Options

ID	Default	Values	Description
gui	true	true	enable support for the UI object and UISET actions
		false	disable UI support
pollinterval	10	n > 0	the data acquisition interval, in minutes
location		<woeid>	WOEID of the target location

The 'location' option is required. To obtain the WOEID of the desired location, go to the Yahoo! Weather home page and enter the location name in the search field. The WOEID will be at the end of the URL for the forecast page for that location. For example, if you search for Los Angeles, the forecast page for that city is "http://weather.yahoo.com/united-states/california/los-angeles-2442047". The WOEID is 2442047.

Conditions and categories

The following table shows the possible weather condition values and their categorization.

Categories are used to summarize relevant aspects of a specific condition so to simplify programming logic. The available categories are: clear (c), precipitation (p), storm (s), partly cloudy (pc), and low visibility (lv). For some conditions (e.g. “windy”) the categorization is not feasible; in such cases (denoted by "xx") the category datapoints will not be updated so to maintain the previous condition.

Condition	Categories
blowing_snow	p, lv
blustery	xx
clear_night	c
cloudy
cold	xx
drizzle	p
dust	lv
fair_day	pc
fair_night	pc
