Motivation
This project can be a very good starting ground, which it can be taken
further to allow a home owner to control, monitor and co-ordinate
home appliances remotely using the internet or remote device such as
mobile phone.

Installing DeviceHive on Raspberry Pi
and Run the Program
Access your device from Devicehive Admin UI
and Create Client App
See the device and the readings from the sensor in Admin UI
http://nn5761.pg.devicehive.com/admin
Send on/off messages to the LED: Name: UpdateState
Parameter: {"equipment":"LED","state":"1"}
Create client App to switch on/off the LED and get temperature
readings
Access your device from Devicehive Admin UI
and Create Client App
Conclusion
Our internet-enabled temperature sensor and LED are now talking to
our JavaScript page using DeviceHive.
We just saved ourselves a bunch of time designing the protocol,
implementing libraries, troubleshooting and deploying.
Future Work
 Implement Client app to turn on/off and decrease/ increase the
The temperature.
 Replace LED with power relay and control light in a room,
 Add humidity sensor and light sensors to better monitor the
environment and report everything on your mobile device?
