Yahoo weather bindings - is official tutorial still valid?

Hello folks,
is this tutorial still valid ?

I am gettting errors

2016-10-03 11:08:23.921 [WARN ] [.httpclient.HttpMethodDirector] - Unable to respond to any of these challenges: {oauth=OAuth oauth_problem=“OST_OAUTH_PARAMETER_ABSENT_ERROR”, realm=“yahooapis.com”}2016-10-03 11:08:23.922 [WARN ] [g.openhab.io.net.http.HttpUtil] - Method failed: HTTP/1.1 401 Unauthorized

and

2016-10-03 11:16:23.763 [WARN ] [t.i.s.MapTransformationService] - Could not find a mapping for ‘-’ in the file ‘yahoo_weather_code.map’.

I am aware change at Yahoo´s API (Yahoo Weather issue) anyway is there a workaround ?

If you are on OH 2, see the following for how to configure the Yahoo Binding:

http://docs.openhab.org/addons/bindings/yahooweather/readme.html

The images part of the tutorial you point to should still work. It just provides a mapping between the ConditionID and the proper icon for that condition.

If you are on OH 1, see the following for how to configure the Weather Binding for Yahoo.
