Livolo light switch code sample

[Cristian Muscalu]

Hello, i found this really simple tutorial on turining on/off a Livolo light switch https://www.instructables.com/id/Controlling-a-Livolo-RF-Light-Switch-Using-a-Raspb/

It's the only code i found working, however the problem is i can't really read python and i was wondering if someone can translate this into node maybe using this library.

Thanks!

                GPIO.output(TRANSMIT_PIN, 0)
            else:
                continue
        GPIO.output(TRANSMIT_PIN, 0)
    GPIO.cleanup()

# How to use:: I am putting this here, because it seems few people have figured out livolo switches.
# Hold down livolo light switch for 5 seconds and wait for a beep.
# Run ```python livolo.py on```
# Livolo light switch should beep again, signalling it is paired
# Now running ```python livolo.py on``` will toggle the switch.
# ```python livolo.py off``` is global to all switches and should work out of box.

# The following lines are possible RF codes which can be learned by the switch.
# Just make them strings and save them to variables similarly to 'on' or 'off'.
# I only have 1 switch so multiple RF freqs werent necessary.

This should be pretty straight-forward:

• Replace GPIO.output() with rpio.write()
• Replace time.sleep() with rpio.usleep() and convert to microseconds.

I'd avoid using the BCM numbering, just use the physical numbering that rpio defaults to and set the physical pin you are using instead for TRANSMIT_PIN (in the case of BCM17 that would be physical pin 11).

The rest is basic JS.

When someone sais pretty straight-forward, i't's never like that at all! :D
I have no experience with Python, so pretty much all the code is unclear.

Edit: I'm calling the file like this: const process = spawn('python', ["./livolo.py", 'on']);
