Buttons only work if I access via python first

[gonzonia]

I’ve had this problem for a while and I’m not sure how to fix it.
I’m using MMM-Buttons to switch between scenes from MMM-Scenes and it’s working. However, it only works if I first use a little python test program I have to test the buttons. Why? I don’t even have to actually press a button, just run the python and then exit. After that, the buttons work.

I thought I posted this before but can’t find it. I apologize if this is a duplicate.

Python:

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

GPIO.setup(25, GPIO.IN, pull_up_down=GPIO.PUD_UP)
GPIO.setup(24, GPIO.IN, pull_up_down=GPIO.PUD_UP)


while True:
    input_state25 = GPIO.input(25)
    input_state24 = GPIO.input(24)
    if input_state25 == False:
        print('Button Pressed 25')
        time.sleep(0.2)
    if input_state24 == False:
        print('Button Pressed 24')
        time.sleep(0.2)

A few modules have similar names; which one are you using exactly?

[gonzonia]

@MMRIZE Sorry for the delay I missed your response.

I’m using https://github.com/Jopyth/MMM-Buttons but happy to switch if there’s something better.

I’m using it to switch scenes in MMM-Scenes by sending “SCENES_NEXT” or “SCENES_PREV”

@gonzonia
Is your issue solved?

[gonzonia]

Oh, I’m realized I’m not actually using https://github.com/sdetweil/MMM-Buttons to fix the install issues

[gonzonia]

@MMRIZE No. I still need to run my little test script to get the buttons to work. It’s not a huge deal, I just wonder why that’s the case.

@gonzonia
Sorry, I read the module but found nothing suspicious in that. The module and its dependencies look normal. ATM, I cannot guess the issue.

@gonzonia see this maybe
