Lampshades to fully shield the electromagnetic frequencies which are necessary for the light bulb to be controlled (2015)

A "smart home"-light bulb which is controlable with an app via Wifi is placed inside the lampshade. The lampshades are made of a material which filters electromagnetic frequencies and thus interferes the controllability of the lightbulb.
In this setting, the lightbulb cannot be connected to and is hence converted into a normal lightbulb again.
