Dodání OK. dosud nepoužito.

Eric Boissier
Dispite the DIY claim, it does not seem to work locally without the mobile app..

This is very annoying and desappointing...

Sorry for the bad experience, this device does not support DIY mode, it cannot work locally.

Matīss Rapša
Not working locally

Have tried for 2 weeks to controll the device locally but no luck, also the data lines are disconnected trough the device

Bennett Marks
Only controls the power lines

Wish that you had made it clear that the data lines are left disconnected. Controlling the data with this device is impossible.

Sorry for any inconvenience this has given you! The data cannot be controlled by Micro. We contacted you through email and provided you with a solution; please examine it and we hope to hear from you soon.

Super Adapter

Habe mir dieses USB-Adapter gekauft, um zu testen, ob es genauso gut mit Sprache funktioniert, wie die Steckdosen.
Ich muss sagen, Top Funktion. Einrichtung innerhalb von 1 Minute. Genau das, was ich gesucht habe.
Kann diesen Adapter für USB-Geräte empfehlen.
