Thank you very much for your answer,
Do you mean something like this ?
Before starting this thread I’ve tried the HTTP binding. Unfortunately some examples are obsolete (http://weather.yahooapis.com no longer exists), there are no examples to parse the status info collected with the POST method and last, but not the least, when I’ve tried this binding to issue a change temperature command it failed because the certificate could not be trusted (and I don’t know how to bypass this check). So I felt completly lost.
Furthermore I don’t know if this binding is the correct one to use for this purpose.
