Good product. I waiting more using with google assistant, like start a trigger to use routine. Currently i use only notifications, open close door, not action with this sensor

Philippe Rostin
Great but too Big

The unit works great and was a breeze to Set up. The only problem I see is that it is a bit big when compared to other brands. True thought that with a motion sensor inside it is unique.

Absolut genial

Schon lange war ich auf der Suche nach einer Möglichkeit meine Schiebegardinen smart zu machen. Und Switchbot macht die wirklich smart. Mega einfache Installation, sehr gut erklärte App. Und sehr starke Produkte. Ich hab nun 3 hubs, 2 Curtains, Türkontakt und Thermometer und steuere meine Fernseher und alle anderen Infrarot-Geräte wie Klimaanlage, Staubsaugerroboter per Sprache oder einfach automatisch. Und durch den Bot-bot kann ich sogar meinen Tee früh morgens automatisch genießen. Ganz klar Daumen hoch!
