EDIT : 09 mars 2017 - Mise à jour du premier message pour rassembler toutes les informations nécessaires !
La base du travail est ici : https://openv.wikispaces.com/
C'est en allemand et pas toujours bien documenté.
Un très bon tuto en français qui est une bonne base de départ :
https://www.bricozone.fr/t/interface-vi ... -pi.14671/
Le principe :
Les deux LED d'état qui sont sur la chaudière sont aussi des recepteurs/emetteurs IR série. Il est donc possible de tout faire par le biais de ces LED sans connexion directe avec la chaudière.
Sur le site Allemand OpenV, l'interface documentée est OptoLink USB qui vaut 40€
Il est possible de se fabriquer son interface USB ou série. Ce n'est pas très compliqué et le coût est d'environ 15€. J'ai commencé à en parler ici : viewtopic.php?f=8&t=1891

Le branchement :
Deux solutions :
1/ en serie directement sur le raspberry (/dev/ttyAMA0)
Le 3,3V et la masse sur les broches du raspberry (1 et 9 pour le Pi2/3)
Le TXD/RXD sur les broches 8 et 10 (Pi2/3)
Note : sur PI3, il faut impérativement ajouter dans le /boot/config.txt
Code : Tout sélectionner
dtoverlay=pi3-miniuart-bt
enable_uart=12/ en USB avec un adaptateur (/dev/ttyUSB0)
pour 1€ environ : convertisseur PL2303 USB <-> série.
Il faut choisir un adatateur qui gère le 3,3V et cela fonctionne parfaitement.
Comme la chaudière n'est pas à coté de mon Raspberry domoticz, j'ai tiré un cable RJ45 de 15m entre mon interface et le Pi : aucun problème de communication ! J'ai aussi un cable de 1m entre l'interface et les deux LED IR.
Pi <==15m - 4 fils nécessaires (3,3V/GND/TXD/RXD)==> interface optique <==1m - 4 fils nécessaire (2 fils par led)==> leds sur la chaudière

Liaison avec Domoticz
Je vous propose mon code Python qui va faire le lien entre viTalk et Domoticz.
Ce code "domo2vito" permet :
- de changer le mode de la chaudière (Off / ECS / ECS+chauffage avec programmation / mode vacances / ECS + chauffage On permanent)
- de régler le mode ECO (saving)
- de voir l'état du mode "Cocktail"(party) et de l'arreter (l'activation ne marche pas. Toutefois, avec le réglage du mode, ce n'est pas très génant)
- de régler la température du mode cocktail
- de visualiser la température de la sonde extérieure
- de connaitre la température de consigne (il est possible de la régler si vous n'avez pas de commande à distance type Vitorol 300)
- de connaitre la température réelle mesurée par la sonde intérieure (si elle existe)
- de connaitre la température de la chaudière
- de régler la température d'Eau Chaude Sanitaire (ECS)
- de connaitre la température des gaz de la chaudière
- de la puissance instantanée de la chaudière (en pourcentage)
- des éventuelles erreurs dans les logs de la chaudière (deux derniers événements)
- de régler un interrupteur qui passe à On en cas d'anomalie chaudière
- de mesurer le temps de fonctionnement en seconde de la chaudière entre deux appels du programme
- d'estimer la consommation de gaz de la chaudière
- de régler la température du mode réduit
- de régler la température du mode vacances
- en option, de régler la température du mode normal
Les réglages des températures via Domoticz implique que les réglages des températures via la chaudière soient inopérant. C'est pour cela que pour la température de consigne "normale", je ne recommande pas d'activer cette option (dans le code, elle est désactivée par défaut).
Le programme domo2vito.py (pensez à faire le "sudo chmod +x domo2vito.py " pour le rendre executable)
