Le système d'ouverture du garage écoute sur le port 4280 et attend une requête sur une URL secrète de la part de framateam. Suite à cette requête il ouvre le périphérique série et lui envoie une commande pour procéder à l'actionnement du moteur.

Pré-requis:

apt install python3-flask python3-serial
adduser lov dialout

Code du serveur dans /home/lov/garage:

from flask import Flask
app = Flask(__name__)

            if 'LOV' not in banner:
                return "didn't find the garage opener banner"
            f.write(b'O')

Pour lancer au boot du serveur dans rc.local:

sudo -u lov -g lov /usr/bin/python3 server.py 2>&1 >/var/log/garage.log &
