[TUTO] KNX --> Home Assistant via Node-Red

[Ives]

Objectif général : piloter un appareil non KNX depuis un bouton KNX comme, par exemple, un prise commandée Wifi. 
N'ayant pas ce type d'appareil dans mon installation, j'ai utilisé une entité "Light" de Home Assistant afin de vérifier le code proposé.

Objectif du tuto: Changer l'état d'une entité "light" de Home Assistant lors d'une action sur un bouton KNX (paramétré en mode toggle)



1) Prérequis
- Installer l’add-on Node-Red dans HA : HA/Paramètres/Modules complémentaires / Boutique des modules complémentaires 
- Installer KNX Ultimate dans Node-Red 

•    NR/Menu/ Manage Palette
  

• Onglet Install : rechercher « node-red-contrib-knx-ultimate » et l’installer puis redémarrer Node-Red
  

 
2) Bouton KNX à Entity Light de HA

- ETS : GA du bouton


-Node Red
