Un excellent produit, je ne pensais pas qu'on aurait un truc aussi bien fichu et versatile pour le prix. Pratique à appairer, pratique à configurer avec un serveur web intégré. Il faut mettre à jour le firmware (celui livré date de 2020 et n'est plus supporté par l'intégration dans Home Assistant), mais c'est très facile. Ensuite activer le protocole CoIoT dans les réglages, et ce que j'avais oublié au début, configurer la communication en unicast sur l'adresse ip:5683 où ip est l'adresse du système domotique, sinon la communication multicast par défaut n'est pas fiable. Une fois le module configuré, il marche comme un charme, avec simple, double ou triple clics, click long ou clic mixte sur chaque entrée, c'est excellent. Bref, maintenant que le premier marche, je risque d'en acheter d'autres...
