Thank you, @rlkoshak ! I understand how that works together now!
for others my new.cfg: #weather:location.Home.latitude=37.28424 #weather:location.Home.longitude=-80.04353
weather:location.Home.woeid=2487363
weather:location.Home.provider=Yahoo
weather:location.Home.language=en
weather:location.Home.updateInterval=10
.items: Number Weather_Temperature "Outside Temperature [%.0f] °F" <temperature> { weather="locationId=Home, type=temperature, property=current, unit=fahrenheit" }
Are you getting valid values from the Yahoo-weater? I found it absolutely unreliable, see further Yahoo weather: data unreliable, binding problems
The “bad data” returned by Yahoo is not a fault of OpenHAB!
