Weather Binding problems with Yahoo

[kevin]

For the past few days I’ve noticed many errors in my logs when using the Weather binding to query Yahoo. The errors are

2017-05-17 05:23:34.047 [WARN ] [ther.internal.parser.CommonIdHandler] - CommonId not found: CommonIdHandler[provider=YAHOO,id=<null>,icon=<null>]
2017-05-17 05:23:34.062 [WARN ] [eather.internal.bus.WeatherPublisher] - Weather forecast day 0 not available for locationId 'home', only 0 available
2017-05-17 05:23:34.067 [WARN ] [eather.internal.bus.WeatherPublisher] - Weather forecast day 0 not available for locationId 'home', only 0 available

Taking a look at Yahoo’s documentation it has examples of how to query the API, which return a not authenticated error

http://weather.yahooapis.com/forecastrss?w=2502265 for example gives

<yahoo:error xmlns:yahoo="http://www.yahooapis.com/v1/base.rng" xml:lang="en-US" yahoo:uri="http://yahoo.com">
<yahoo:description>
Please provide valid credentials. OAuth oauth_problem="OST_OAUTH_PARAMETER_ABSENT_ERROR", realm="yahooapis.com"
</yahoo:description>
<yahoo:detail>
Please provide valid credentials. OAuth oauth_problem="OST_OAUTH_PARAMETER_ABSENT_ERROR", realm="yahooapis.com"
</yahoo:detail>
</yahoo:error>

A further google leads to a blog post which suggests that “Yahoo effectively shut down its Weather API by forcing OAuth 1.0 and crippling it”

Does this mean the weather binding is broken when talking to Yahoo?
Any chance of a fix?

Nope. Mine works - mostly. Meaning sometimes the OH query fails (with CommonId not found) and sometimes it doesn’t. Sometimes it is fine for days. A couple of month ago it failed practically every time, then with no OH changes resumed working well. I think its just a response time issue at the Yahoo end.

People quite often get fed up with Yahoo and use alternate weather providers for this reason. A recent discussion

OH1.8: Wunderground config (ditch Yahoo)

I have a perfect Yahoo setup in sitemap, items, and web widget… working for more than a year now. Yahoo is having forecast problems for the last few days, filling up my log with errors, resulting in a broken web widget, etc.; in short: only trouble, and I had it. So I got a Wunderground API key and thought all I need to do is change the openhab.cfg… well, that would be too easy. I realise that I need to change items, which access the Yahoo Cache, where the items pull their info from. My plea…

Thinking about it mine isn’t totally broken, just broken for a large proportion of the time. Last time I looked around Yahoo was the most accurate, but I’ll take a look and see if any of the other providers have improved in the last few months.
Thanks for the reply

I’m querying Yahoo every hour, and checking my logs it fails 10 times per day on average (worst was 12 times, best 6 times). Using the litlle “workaround” (see post 8 in linked thread) I put in place I’ve decided to stay with yahoo - just too much hassle changing to another provider imho…
