Good morning and thanks very much for all your research and work on the latest release. Data is now being uploaded perfectly to my ThingSpeak channel :-).

Just to let you know, there is a small error in the compact Rx code: the WU Credentials names are different on the Credentials.h tab to the NET tab. In the Credentials.h tab the names are:
 

Code:

// --------------------------------------------------------------------------------------
//   WU Credentials 
// --------------------------------------------------------------------------------------
const char* WU_STATION_ID = "ISHIRENE2";         // WU Station ID
const char* WU_PWD        = "FIXV9HBT";         // WU Station Key

On the NET tab they are:

Code:

    Data += WUNDERGROUND_STATION_ID;
    Data += WUNDERGROUND_PWD;

I did zero using the method you suggested and i have confirmed it is the B model. I can now see if my sensor is responding normally.

Thank again and kind regards,

Zak
