Turn light On at 08:30 WebIOPi raspberry pi 3

Question

for set hour_on | hour_off, there is in a configuration these command:

HOUR_ON  = 8  # Turn Light ON at 08:00
HOUR_OFF = 18 # Turn Light OFF at 18:00

And it's ok, but if I would set HOUR_ON at 08:30?

Answer 1

You have to modify your sample program to add the functionality for minutes. Please refer to this page for details on Python date manipulation.

This page explains how to modify loop function to add minutes functionality,

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)
