Z-wave Smart Film is a window cover technology. It’s like a curtain, but it doesn’t hang in front of your window. Instead it applies directly to glass. It allows glass to be transparent. It allows glass to be opaque. It lets light through. Smart Film is the modern curtain. One focussed on privacy. One focussed on saving energy. One available at the push of a button. Smart Film never proved as user-friendly to install as we expect from all of Aeotec's products to be.
