Vive le Vent!

Cette application est très pratique quand on veut déclencher à distance son ventilateur de plafond, mais pas seulement !
Changer de vitesse de rotation quand vous n’avez pas la télécommande sous la main par exemple !

Much improved!

I’ve had there infrared wall heater in my downstairs WC for a number of years . Absolutely brilliant product. I think it’s the only one on the market with an app connection, timer and thermostat. The app has got better over the years. We’ve just turned it on since the spring and it’s remembered all the settings.

D’une fiabilité remarquable

Une appli d’une fiabilité remarquable, appareil débranché, rebranché, balader partout, coupure internet, arrêt de utilisation de plusieurs mois de l’appareil et autre, jamais eu de coupure entre l’appli et l’appareil. Le pilotage fonctionne à merveille depuis plus de 2 ans. Top

Communiquer avec son déshumidificateur

Je trouve très pratique de pouvoir régler mon déshumidificateur aussi bien avec la télécommande et avec la Wifi et l’aide d’Alexa d’Amazon.

La perfection

Super pratique la gestion wifi ! Super application ! Simple et rapide !!
