The IoT Smart Home System is intended to provide seamless control and automation of connected devices within a home environment. The system should cater to the following key requirements:
Based on the requirements, the core objects in the system include:
SmartHome contains multiple Devices. Each Device is uniquely identifiable and associated with a communication protocol.User can access and control a SmartHome system based on their role.Rules are associated with specific Devices and define automation or scheduling logic.Devices based on predefined conditions.Controller facilitates interaction between the SmartHome system and Devices.To promote reusability, we use inheritance to define common attributes for Device and its subtypes:
Thermostat, Light, Camera, Lockid, name, status, protocolAdminUser, StandardUseruser_id, name, role, permissionsSmartHome controller exists.class Device:
def __init__(self, id, name, protocol):
self.id = id
self.name = name
self.protocol = protocol
self.status = "offline"
def connect(self):
raise NotImplementedError
def disconnect(self):
raise NotImplementedError
class Light(Device):
def turn_on(self):
self.status = "on"
def turn_off(self):
self.status = "off"
class Thermostat(Device):
def set_temperature(self, temperature):
self.status = f"Set to {temperature}°C"
class SmartHome:
def init(self):
self.devices = {}
self.rules = []
def add_device(self, device):
self.devices[device.id] = device
def remove_device(self, device_id):
self.devices.pop(device_id, None)
class User:
def init(self, user_id, name, role):
self.user_id = user_id
self.name = name
self.role = role
class Rule:
def init(self, condition, action):
self.condition = condition
self.action = action
def execute(self):
if self.condition():
self.action()
Device handles device logic, Rule manages automation).Device class.Light, Thermostat) can be used wherever Device is expected.Device) rather than concrete implementations.The system can scale by supporting new devices via subclasses of Device. Flexible rule-based automation allows users to customize device behavior without changes to the core system. Modular controllers ensure that new protocols can be added with minimal impact.
