  With the emergence of the IoT, there is an increasing trend towards designing
a new low-cost cyber-physical platform accessible through the Internet. In this
Demo paper, we present WiSwitch, a homemade prototype of a low-cost wireless
switch control allowing the user to control the room light through the cloud.
The hardware is based on a commercial-off-the-shelf (COTS) ESP 12 WiFi module
with basic electronic circuitry. We develop an embedded client application in
the ESP 12 that allows us to connect it to the Amazon Web Services cloud and
update the status of the switch remotely. We also present an experimental
validation of the WiSwitch platform.
