The Reserachers from University of Southampton have studied ways to ease the set-up of IoT devices in the home. But the issue is that to join a wireless network, security parameters have to be accurately entered into the IoT device, which may have almost no user interface.

IoT objects can be attacked and possibly hijacked, putting our privacy, data and safety in threat. It is believed that not enough attention has been placed on how to make the IoT easy to use and to configure its security.
Four versions of basic techniques were tried, all using a touch screen phone as an interface to enter a password, which the phone will send to the IoT device:
- Holding the phone’s screen against the IoT device and transferring the parameters to a photo cell by flashing the phone screen.
- Use of a USB cable for parameters transfer between the phone and IoT device
- Using a 3.5mm audio jack cable between the phone's headphone socket and the IoT device
- Using the phone to create a temporary ad-hoc Wi-Fi network which the IoT joins automatically.
According to the University of Southampton, the two methods were found to be noticeably more useful than others- the audio cable and the Wi-Fi-only interactions.
