The forecast_table.inc file is a cheetah template designed to be included in other templates. At the beginning of the file is a list of variables that determine which forecast data will be displayed. The forecast_strip displays forecast data in a compact form with time going from left to right. The forecast_strip.inc file is a cheetah template designed to be included in other templates.

[[WU]] api_key = XXXXXXXXXXXXXXXX # specify a weather underground api_key # A location may be specified. If it isn't, your stations lat/long # will be used. # # To specify the location for which to generate a forecast, one can specify # the Geocode (lat, long), IATA Code, ICAO Code, Place ID or Postal Key. # # These options are listed here: # https://docs.google.com/document/d/1_Zte7-SdOjnzBttb1-Y9e0Wgl0_3tah9dSwXUyEA3-c/ # # If none of the following is specified, the station's latititude and longitude # will be used. If more than one is specified, the first will be used according # to the order listed here. # # geocode = "33.74,-84.39" # iataCode = DEN # icaoCode = KDEN # placeid = 327145917e06d09373dd2760425a88622a62d248fd97550eb4883737d8d1173b # postalKey = 81657:US [[OWM]] api_key = XXXXXXXXXXXXXXXX # specify an open weathermap api_key [[UKMO]] api_key = XXXXXXXXXXXXXXXX # specify a UK met office api_key location = 2337 # specify code for UK location [[Aeris]] client_id = XXXXXXXXXXXXXXXX # specify client identifier client_secret = XXXXXXXXXXXXXXXX # specify client secret key [[DS]] api_key = XXXXXXXXXXXXXXXX # specify a dark sky api_key [[XTide]] location = Boston # specify a location 3) restart weewx: sudo /etc/init.d/weewx stop sudo /etc/init.d/weewx start This will result in a skin called forecast with web pages that illustrate how to use the forecasts.
