Hi Jim,
thank you for your answer. I'll try it with the "string methode". Before I
tried to adapt the lines at the bottom of the aleksander's (the original)
driver version:
* if 'windSpeed_mwd' in data and data['windSpeed_mwd'] is not
None: data['windSpeed'] = data['windSpeed_mwd']
elif 'windSpeed_mda' in data and data['windSpeed_mda'] is not
None: data['windSpeed'] = data['windSpeed_mda']*
With my above added dictonary entry "SOG_kn":
* try: data['COG_degTrue'] =
float(buf[1]) data['COG_degMag'] =
float(buf[3]) data['SOG_kn'] =
float(buf[5]) data['SOG_kmh'] =
float(buf[7]) except (ValueError):
pass loginf("Wrong data format '%s, %s, %s, %s'" %
(buf[1], buf[3], buf[5], buf[7]))*
But weewx always complains about *KeyError: 'SOG_kn'. *After some
google-sessions I found out, that this is python typical, if there is no
dictonary entry for SOG_kn...which is fine, as long as I am testing on the
desk with no GPS signal, but outside with values for SOG_kn (even
displayable in grafana) I'm still receiving this error.
And, I'm afraid, that I am not the Dennis who works with Cooper in Denmark
;-)
I'm here in Munich, Germany ;-)
