Weather Binding throws many forecast not available errors

Add-ons Bindings

All-

I am using the weather binding with OpenWeatherMap. The system seems to be working fine, but in my Openhab.log file, there are a huge number of errors that read:

[ERROR] [b.w.i.gfx.WeatherTokenResolver:78 ] - Weather forecast day 2 not available, only 0 available
java.lang.RuntimeException: Weather forecast day 2 not available, only 0 available.

etc. Does anyone have any ideas? I am refreshing every 10 minutes, but these errors periodically occur and are logged every few seconds. The logfile is getting big.

Many thanks,

Same here…

Sometimes it seems to work and all data will be displayed, but mostly it fills up my logfile with the above mentioned errors.

I´m using OpenHAB v1.8.2.

Thanks

Could you replace your weather JAR with this one and tell me if the log spam decreases to single-line WARN messages instead of full ERROR messages with stack traces? Would this change be worth submitting a pull request?

Thanks for your help. - I´ve replaced the JAR and it seems to reduce the spam as you had assumed

2016-04-03 19:50:01.932 [WARN ] [b.w.i.gfx.WeatherTokenResolver] - Weather forecast day 0 not available, only 0 available
2016-04-03 19:50:01.934 [WARN ] [b.w.i.gfx.WeatherTokenResolver] - Weather forecast day 1 not available, only 0 available
2016-04-03 19:50:01.936 [WARN ] [b.w.i.gfx.WeatherTokenResolver] - Weather forecast day 2 not available, only 0 available

…but still 90% downtime of the weather-webview. I´ll give OpenWeatherMap a try…

All-

I am also running Openhab 1.8.2. I noticed that if I reduce the update frequency to every 60 minutes (as opposed to every 10 minutes as in the default configuration) these errors disappear. That said, I just replaced the JAR with the recommended 1.9 SNAPSHOT - will let you know if there are further issues.

Many thanks,

-Mark
