With the end of the YahooWeather API, I signed up for some API keys from OpenWeatherMap’s free tier, but had real trouble getting the default weather binding to work. After many wasted hours puzzling over the following error message, I eventually found this thread.
[ERROR] [nal.provider.AbstractWeatherProvider] - OPENWEATHERMAP[home]: Can't retreive weather data: Invalid API key. Please see http://openweathermap.org/faq#error401 for more info.
The error is correct, but uninformative – the issue is that default binding is calling on the “paid for” API rather then the free one, so yes my free API key is invalid for the API call I’m making. Unfortunately that is less then informative when testing your API keys in a browser and receiving valid JSON!!
The solution for me was to add org.openhab.binding.weather-1.13.0-SNAPSHOT.jar to my addons directory, then using the following weather.items I was up and running:
