====== Jeedom sur Raspberry PI 2 ou 3 ======

Avec l'installation via Docker.

<code>
pacman -S docker
</code>

Mettre son utilisateur courant dans le groupe docker (pour éviter sudo).

Utilisation de l'image suivante [[https://hub.docker.com/r/sbeuzit/rpi-jeedom/|https://hub.docker.com/r/sbeuzit/rpi-jeedom/]] avec les commandes qui suivent:

<code>
docker pull sbeuzit/rpi-jeedom-data
docker run --name data sbeuzit/rpi-jeedom-data
</code>

Cette image ne sert que pour conserver les données. Il faut ensuite un containeur pour la partie MySQL :

<code>
docker pull hypriot/rpi-mysql
docker run --name jeedom-mysql -e MYSQL_ROOT_PASSWORD=my_mysql_password --volumes-from data -d hypriot/rpi-mysql
</code>

Il s'agit de l'image fournit pas hypriot, donc idéale pour Raspberry PI. A noter qu'il faut plus de 512Mo de RAM, donc il faut un minimum un RPI 2 ou supérieur.

Il ne reste plus qu'à lancer le containeur jeedom avec le lien vers nos containeurs précédents :

<code>
docker run -d --link jeedom-mysql:mysql --device=/dev/ttyUSB0:/dev/ttyUSB0 --name jeedom -p 80:80 -p 8083:8083 -p 443:443
</code>

A noter le /dev/ttyACM0 pour donner accès à votre clef ZWAVE.

====== Domoticz sur Raspberry PI B+ ======

Récuperer les sources et les compiler (pas trop lourd même sur un RPI).

Configuration de tellstick duo pour piloter une prise DIO fichier /etc/tellstick.conf :

<code>
user = "root"
group = "plugdev"
deviceNode = "/dev/tellstick"
ignoreControllerConfirmation = "false"
device {
  id = 1
  name = "Aquarium Nano"
  controller = 1
  protocol = "arctech"
  #model = "codeswitch"
  model = "selflearning-switch"
  parameters {
    # devices = ""
    house = "A"
    unit = "1"
    # code = ""
    # system = ""
    # units = ""
    # fade = ""
  }
}
controller {
  id = 1
  # name = ""
  type = 2
  serial = "A6028BOC"
}
</code>
