Jeedom est un logiciel Open Source d’origine française, qui vous permet de créer votre propre centre de contrôle domotique. Le logiciel peut s’installer sur un Raspberry Pi (ce que je vais utiliser), mais vous pouvez aussi acheter du matériel Jeedom plus performant si vous le souhaitez. Par l’intermédiaire d’un système de plugins disponible sur une place de marché, Jeedom peut s’interfacer avec de nombreux matériels et capteurs de type Z-Wave, RFXCom, EnOcean, etc.
