parfait, le module est assez petit. j'ai réussi à l'intégrer à l'intérieur d'un interrupteur. j'ai choisi de mettre l'interrupteur entre S1 et S2, du coup je peux soit mettre en route avec l'interrupteur physique ou par l'application Ewelink. il a fallu mettre à jour le logiciel du mini interrupteur

Bon à savoir : Curieusement, impossible de finaliser le pairage (inscription EweLink) de ce MINI R4 en passant par un accès internet réalisé via un routeur 4G (TENDA 4G03 PRO). En passant par une box ADSL SFR, aucun de problème. Sinon le mini R4 ne pose pas de problème malgré sa petite taille
