HOUR_OFF = 18 # Turn Light OFF at 18:00

您必須修改示例程序以添加分鐘功能。 有關Python日期操作的詳細信息，請參閱this page。

This page說明如何修改loop函數添加minutes功能，

def loop(): 
    # Get the current time 
    now = datetime.time(datetime.datetime.now().hour, datetime.datetime.now().minute) 

    # Automatically switch on LED 
    if ((now.hour == HOUR_ON.hour) and (now.minute == HOUR_ON.minute) and (now.second == 0)): 
     if (GPIO.digitalRead(LIGHT) == GPIO.LOW): 
      GPIO.digitalWrite(LIGHT, GPIO.HIGH) 

    # Automatically switch off LED 
    if ((now.hour == HOUR_OFF.hour) and (now.minute == HOUR_OFF.minute) and (now.second == 0)): 
     if (GPIO.digitalRead(LIGHT) == GPIO.HIGH): 
      GPIO.digitalWrite(LIGHT, GPIO.LOW) 

    # Repeat every 1 second 
    webiopi.sleep(1)
