### ⭐⭐⭐⭐⭐ Review
*by J***E on 9 June 2025*

-Je ne voulais pas particulièrement d'aqara (pour ne pas ajouter une nouvelle marque à mon réseau), mais le sonoff est trop gros à mon gout avec aqara seul à ce niveau de prix et ce niveau de rapport qualité prix (exit Moes, Nous et co qui fonctionnent quand ça veut). Sans surprise c'est parfait, réactivité instantanée à l'ouverture, mois d'1 seconde à la fermeture. -Ajouté à home assistant via zha en 1 clic avec le niveau de batterie et les variables de qualité réseau/connectivité zigbee remontées. C'est mis à la va-vite vite sur la porte pour le test, je pense qu'il y a moyen de cacher le capteur sous la porte avec la partie fixe montée perpendiculairement. On est pas dans le gadget me concernant car il m'arrive "régulièrement" de mal fermer ma porte de congélateur (j'ai une alerte home assistant à 2 min d'ouverture de porte) ... -Aussi, je confirme que la partie mobile du capteur est aimantée (et scotch double face fourni malgré tout pour cette partie). edit : si vous avez l'impression que le capteur se met en position "ouvert" avant l'ouverture physique de la porte, c'est parce-que c'est le cas (les 2 clips sont biens synchronisés). Là ou j'ai placé l'aimant, les 2 ou 3mm ou je tire sur la porte (avec l'accordéon de la porte du congélateur qui compense physiquement la déformation) suffisent à activer le capteur.
