Energenie RF Switch Adaptor

Energinie / miHome single gang UK wall switch adaptor for RF light switches.

These require a minimum 25mm back box to fit flush with the wall. All of them in my house are 15mm deep, so this makes up the difference without the need for chiselling out a deeper pocket and installing a 25mm box.

Doubles up as a finger guard around the switch so no mucky finger prints on the wall when you're looking for it in the dark... Of course, you could just shout out 'hey Siri, turn on the lights' :)
