Hola "jantoni":
He revisado el "skin" y no veo donde configurar el parametro que estamos comentando. Solamente en el Grupo "Groups" se hace referencia a las unidadces de medida y los datos que contiene no son los que se crean en el fichero "index.html" (ver en "Captura1.jpg" del primer mensaje)
El grupo "Groups" del skin tiene lo siguiente:
[[Groups]]
# For each group of measurements, this section sets what units to
# use for it.
# NB: The unit is always in the singular. I.e., 'mile_per_hour',
# NOT 'miles_per_hour'
group_altitude = foot # Options are 'foot' or 'meter'
group_degree_day = degree_F_day # Options are 'degree_F_day' or 'degree_C_day'
group_direction = degree_compass
group_moisture = centibar
group_percent = percent
group_pressure = inHg # Options are 'inHg', 'mmHg', 'mbar', or 'hPa'
group_radiation = watt_per_meter_squared
group_rain = inch # Options are 'inch', 'cm', or 'mm'
group_rainrate = inch_per_hour # Options are 'inch_per_hour', 'cm_per_hour', or 'mm_per_hour'
group_speed = mile_per_hour # Options are 'mile_per_hour', 'km_per_hour', 'knot', or 'meter_per_second'
group_speed2 = mile_per_hour2 # Options are 'mile_per_hour2', 'km_per_hour2', 'knot2', or 'meter_per_second2'
group_temperature = degree_F # Options are 'degree_F' or 'degree_C'
group_uv = uv_index
group_volt = volt
# The following are used internally and should not be changed:
group_count = count
group_interval = minute
group_time = unix_epoch
group_elapsed = second
Un Saludo. Gracias
