The Oprillo Plug is the key piece of hardware in the Oprillo Project. The componentry held inside connects wirelessly to the home's internet network and provides a communication channel between the Oprillo User Platform in the Cloud, and the devices in the home that the user wishes to control. It is designed ergonomically to be comfortable to hold and push and pull into place in a plug socket. All the feedback to the user is provided using an LED. It was prototyped using a combination of 3d Printing and Vac Forming.
