Im working on doing some remote GPIO control (de)energizing relays. When I turn a relay on, it instantly turns off. That makes me assume that the output doesn't latch. I tried several of the classes used to control digital IO remotely but all of them behave the same.

from gpiozero import OutputDevice
from gpiozero.pins.pigpio import PiGPIOFactory

factory = PiGPIOFactory(host='d1p-woctorelay.local')


#RD1P Relays
las_test = OutputDevice(15, pin_factory=factory)


las = LED(5, pin_factory=factory)


rex = LED(6, pin_factory=factory)


ras = LED(13, pin_factory=factory)


las_test.on()


las.on()


rex.off()

Is there something I'm missing in the docs or some basic trick to latching remotely? I came across this SO post but it doesn't seem to work the same for remote control.

Im not sure about the why but as I built the script it started working as expected.

import argparse
from gpiozero import OutputDevice
from gpiozero.pins.pigpio import PiGPIOFactory

import argparse


parser = argparse.ArgumentParser(description='Start, stop, or start aux equipment')
parser.add_argument('func', type=str, required=False, help='Function to perform [startup, shutdown, auxstart]')


args = parser.parse_args()


factory = PiGPIOFactory(host='d1p-woctorelay.local')


#RD1P Relays
las = OutputDevice(15, pin_factory=factory)
rex = OutputDevice(6, pin_factory=factory)
ras = OutputDevice(13, pin_factory=factory)


def startup():
    print('Starting up the machine.')
    las.on()


def shutdown():
    print('Shutting down all equipment.')
    las.off()
    rex.off()
    ras.off()


def auxstart():
    print('Starting up the auxilliary equipment.')
    rex.on()
    ras.on()


if name == "main":
    func = args.func
    if func == 'startup': startup()
    elif func == 'auxstart': auxstart()
    else: shutdown()
