# Problem 1: Smart Home Device Hierarchy

"""
Instructions:
1. Create a base class called 'SmartDevice' with attributes for device name, connection status, and power status
2. Implement methods to turn on/off the device and connect/disconnect from WiFi
3. Create a child class 'SmartThermostat' that inherits from SmartDevice
4. Add temperature-related attributes and methods to the SmartThermostat class
5. Test your implementation with the provided test cases

Your SmartThermostat class should have methods to:
- Set the target temperature
- Read the current temperature
- Adjust the HVAC mode (heat, cool, off)
