O well, everything except 'nl' will just show # the english version. :) # # [buienradar*] # env.language = 'en' # env.temperature = 'yes' # env.temperature10cm = 'yes' # env.humidity = 'yes' # env.windspeedMS = 'yes' # env.windspeedBF = 'yes' # env.airpressure = 'yes' # env.view = 'yes' # env.gusts = 'yes' # env.rain = 'yes' # # # ### Installation Example # Below is a example to monitor station Venlo (6391).
