Linux/Mac (Terminal)

chmod +x lamp_control.sh                   # Make executable
./lamp_control.sh 192.168.1.100 on         # Turn on
./lamp_control.sh 192.168.1.100 timer 60   # 1 hour timer
./lamp_control.sh                           # Interactive menu

Python (Cross-platform)

pip install requests                        # Install dependency
python lamp_control.py 192.168.1.100 on    # Turn on
python lamp_control.py 192.168.1.100 status # Check status
python lamp_control.py                      # Interactive menu

🔌 Wiring

ESP8266 NodeMCU    →    5V Relay Module    →    Buzzer
────────────────────    ─────────────────    ─────────
VIN (5V)           →    VCC
GND                →    GND                 →    GND
D1 (GPIO5)         →    IN
D7 (GPIO13)        →                         →    Positive (+)

Relay Module       →    Lamp
─────────────      →    ────
COM                →    Live wire (from wall)
NO                 →    Live wire (to lamp)

🚀 Setup

1. Install Arduino IDE

• Download from arduino.cc
• Add ESP8266 board: File → Preferences → Additional Board Manager URLs:

  http://arduino.esp8266.com/stable/package_esp8266com_index.json
  

• Tools → Board → Boards Manager → Install "esp8266 by ESP8266 Community"
• Select: Tools → Board → NodeMCU 1.0 (ESP-12E Module)

2. Configure WiFi

Open mcu_smartlmp.ino and change:

const char* ssid = "YOUR_WIFI_NAME";
const char* password = "YOUR_WIFI_PASSWORD";

3. Upload Code

• Connect ESP8266 via USB
• Select correct Port in Tools → Port
• Click Upload (→ button)

4. Find IP Address

• Open Tools → Serial Monitor (9600 baud)
• Press Reset on ESP8266
• Note the IP address shown

5. Access Interface

Open web browser and go to the IP address from step 4.

� Troubleshooting

WiFi won't connect:

• Check credentials are correct
• Ensure 2.4GHz network (ESP8266 doesn't support 5GHz)
• Move closer to router

Can't upload code:

• Check USB cable and drivers
• Try different COM port
• Hold FLASH button during upload

Relay doesn't work:

• Verify wiring connections
• Check relay power LED
• Test with multimeter
• Use appropriate voltages - 3V VCC 3.3V VIN signal or 5V VCC 5V VIN (via logic level converter)

Can't access web page:

• Check IP address in Serial Monitor
• Ensure device on same WiFi network
• Try different browser

⏰ Alarm System

The smart lamp now includes a comprehensive alarm system:

Setting Alarms

• Web Interface: Use the "Alarm" tab to set date/time
• Command Line: Use control scripts with alarm commands
• Real-time Sync: Automatically syncs with NTP servers
• Timezone: Configured for UTC+5:30 (Sri Lanka)

Alarm Features

• Date & Time: Set specific alarm date and time
• Lamp Control: Option to turn lamp on when alarm rings
• Buzzer Alerts: Audio alerts with customizable patterns
• Snooze Function: 5-minute snooze intervals
• Auto-stop: Automatically stops after 13 rings (1 hour)
• Persistence: Alarm settings saved to EEPROM
