Hola, no aparezco en el mapa. No debe ser tan sencillo como dices, sólo poner True. Parece ser que es necesario tener página web, cosa que no todos tenemos:
To add your station to this list, you must do two things:
1- Enable the StationRegistry in weewx.conf by setting the option register_this_station to True. Your station will contact the registry once per week. If your station does not contact the registry for about a month, it will be removed from the list.
2- Provide a station_url, either in section [Station], or in the [[StationRegistry]] section.
Si hay otra forma , agradezco información. Salud.
