Temporisation de petite taille et que je parametre depuis mon smartphone jour par jour où hebdomadaire. possibilité de l'activer manuellement. superbe et à un prix vraiment mini. très facile de mise en service.
Utilisé avec Smart life pour ouvrir et fermer mon portail motorisé par Somfy. Pas un contact sec direct mais il suffit d'activer et désactiver de suite pour faire comme si ça en était un.

articolo arrivato in tempi brevi in Italia, l'ho utilizzato per l'apertura di un cancello elettrico, funziona correttamente, un riconoscimento da parte di Smart Life molto veloce. bisognerà valutare la durata nel tempo. comunicazione con il negozio ho messo tre stelle perché non è stata necessaria, quindi non valutabile
