Bonjour,
Mon problème
Je dispose des capteurs de porte Ikea Thread et une prise Tapo Matter Wifi. Depuis ce midi je suis coupé d’internet et je n’ai plus aucun appareils Matter accessible. Ils sont tous indisponibles dans Home Assistant, qu’ils soient sur le protocole Thread ou Wifi. Je pensais qu’avec Matter il était possible de continuer à piloter ses appareils en locale même sans connexion internet. Pour le détail, c’est le câble fibre optique qui s’est plié ce midi et une intervention est prévu ce jeudi. D’ici mes appareils apparaissent hors ligne.
Peut-être aussi que c’est un problème dans ma configuration. En tout cas l’IPV6 est toujours activé du côté de Home Assistant (en automatique sur les interfaces réseaux end0 et wlan0 mais champs serveur dns vide depuis la coupure). Aussi, le changement qu’il y a eu depuis cette coupure, c’est que mes appareils ont toujours des adresses IPV4 assignées mais plus d’adresses IPV6. Du coup est ce que le problème provient du côté de mon modem Bouygues (Bbox Wifi 7), du Thread Border Router ou d’une configuration dans Home Assistant ?
Pour information j’avais activé DHCPV6 du côté de la Bbox (je ne sais pas s’il y a un lien). Côté config on ne peut pas faire grand chose sur l’interface d’administration de la box si ce n’est d’assigner des IPV4 et IPV6 statiques aux appareils du réseau local. Mais l’assignation de l’IPV6 à un appareil ne se fait seulement quand internet est disponible.
N’étant pas un spécialise réseau, si quelqu’un a une explication je suis preneurs. ![]()
Ma configuration
Thread Border Router : Clé Sonoff Zbdongle E avec le dernier firmware Thread (2.4.4).
