Smart Home Development - Light Control#

I have decided to create my own smart home system that lets you turn lights on and off with your phone.
This system would offer a variety of convenient features:

• Turning lights on and off from bed with your phone
• Turning off lights remotely when you forget and leave them on while going out
• Automatically turning off all lights at midnight
• Automatically turning on lights at 7am
• Automatically turning on lights when you enter the house after being out
• Automatically turning off lights when the house is empty

Just imagining it sounds incredibly convenient.
