This project revolves around creating a Smart Home system that automates both blinds and lighting using a NEMA 23 stepper motor and a Yeelight smart lamp, all controlled by an ESP32 microcontroller. The system integrates WiFi-based automation, providing a smart environment where you can control the blinds and the lighting seamlessly. The blinds are powered by a motor enhanced with a planetary gearbox, and the Yeelight lamp is set to follow a specific schedule for a more convenient waking routine.
The ESP32 microcontroller is connected to a local WiFi network and handles automation for both the blinds and the Yeelight lamp. The system is synchronized with NTP (Network Time Protocol) to ensure time-based actions are precise.
-
Blinds Automation: The blinds open automatically at 6 AM on weekdays and at 9 AM on weekends, and they close at 10 PM every day to provide privacy and security.
-
Lamp Automation: The Yeelight smart lamp automatically turns on at 6 AM on weekdays and 9 AM on weekends, simulating a natural sunrise to help you wake up gradually. The lamp will automatically turn off after 1 hour to ensure you aren't disturbed by the light for too long.
The system includes manual control via physical buttons on the ESP32, allowing you to:
- Move the blinds up or down manually at any time.
- Turn the Yeelight lamp on or off with a button press.
The "Sovmorgon" (lie-in) feature allows you to skip the scheduled automation for a day. By pressing a button, you can disable the automatic operation, so the blinds and lamp won't operate at their usual times, perfect for weekends or lazy mornings.
-
Planetary Gearbox for Blinds: The blinds are operated with a stepper motor enhanced by a planetary gearbox, providing up to 4-5 times more torque, making the motor strong enough to move the blinds smoothly even under load.
-
Time Synchronization: The system is synchronized with NTP to ensure that all automation happens at the correct time each day.
-
Manual Control: Manual buttons let you control the blinds and Yeelight lamp, providing flexibility in scheduling and overriding automation.
-
Power Failure Recovery: The system saves the last known position of the blinds using EEPROM memory, so after a power failure, the blinds will return to their correct position.
-
Smart Wake-Up: The Yeelight lamp turns on automatically at scheduled times (6 AM on weekdays and 9 AM on weekends) to simulate sunrise and help you wake up. The light will automatically turn off after 1 hour, ensuring you're not disturbed by it for too long.
- Convenience: Automation makes it easy to control your blinds and lighting based on time or preference.
- Customizable Wake-Up Routine: The Yeelight lamp simulates sunrise, providing a gentle wake-up experience, and will automatically turn off after 1 hour for a comfortable morning.
- Manual Override: Manual control via buttons allows you to bypass automation whenever you want.
