J'avais bien retiré les # sur les 4 lignes lors des essais.
Après avoir parcouru le net, j'ai modifié le script et il y a un peu de nouveau mais cela ne marche toujours pas:

le capteur idx =49 est de type Thermomètre
J'ai fait normalemnt un crontab -e pour exécution du script toutes les 10 minutes
Si j' exécute manuellement le script:
=> les valeurs affichées en console sont correctes
=>il y a rafraichissement du capteur température mais il semble afficher un mélange des 2 valeurs (temp+pression)
[img]file:///home/ob/Bureau/Capture%20d%E2%80%99%C3%A9cran_2017-02-14_00-48-46.png
[/img]
les valeurs étaient t=13.70°C et p=1012.99hPa
=> rien d'affiché dans le capteur Barometer
=> il n'y a pas d'exécution automatique répétée du script
Merci d'avance pour vos conseils.
