Everyone knows SAP HANA Cloud Platform has provided many services e.g. - Mobile service , Document service. Every one has HCP trial account but most of us not explore every service or features of HCP Platform. I was exploring something on SCN and found HCP IOT service then i started exploring it thanks to Rui Nogueira he had posted awesome blogs on HCP IOT.
After reading blogs and help.sap documents i decided to create demo app but issue was i didn't have RaspberryPi device 
. I was thinking can we use existing elements for HCP IOT service 
. I got idea to control Keyboard Led and Laptop using HCP IOT and UI5 App so i've created this simple demo.
Initial phase my design was -
Used 3 components -
1) Python program - Raspberrypi.py
2) HCP Iot service configuration
3) UI5 app for mobile
Final Execution - Watch this video
I'll update source code in my github and more information for implementation this simple HCP Iot demo in my blog series.
If anyone doesn't know about -

Raspbeery Pi you can find here https://www.raspberrypi.org/

In my next blog will show you more realistic demo on HCP IOT with Raspberry pi
