bonjour Mike ,
je vais faire simple ,j'essaye de faire fonctionner une weather station.
https://github.com/T...weather-station
comme tu l'as dit il faut tester une chose à la fois .
j'ai essayer de me connecter depuis chez moi .
j'ai mis la cley API http://openweathermap.org/
et normalement je devrais avoir voir photo du site .
et moi je n'ai que des points .
joins le code.
merci d'avance .bonne soirée.
