[MMM-Buttons] Connect multiple buttons to send configurable notifications

[Burner911]

This sounds awesome! Do you think there is a relatively easy way to output from the GPIO instead? I would like to turn my TV off using a transistor being it does not support HDMI-CEC like a monitor does. I’m thinking this might be best discussed with regards to MMM-Remote-Control.

Nice! I think many people will be able to use this for their mirror

Hi @Jopyth !

Thanks for your module.

I would like to use an on / off button instead of a push button
for my garage door project (https://forum.magicmirror.builders/topic/1620/garage-door-detectors)

Is there a way to send a notification on “button_up” and an other notification on “Button_down” ?

Thank you very much ;-)

Does anyone know how to read the initial value of a button (GPIO) before it is run ?

Thanks.

@Jopyth Moved my post here out from another thread.

I am having one more issue though. Using a python test program i can see every single instance of my button press is registered instantly. But in the mirror it seems MMM-Buttons doesnt register pushes unless sometimes I double or triple click…then sometimes the button registers 5-6 times. I’m not really sure how to debug this sort of thing.

Also would it be right to assume the pull up/down resistors were not enabled with MMM-Buttons?

@Mar i have same problem. I run my little script button.py before start MM and its solve the problem

@istepgueu Ive taken your button.py program and modified it for me two buttons 5/6. And while the program reads my button presses perfectly, MM-Buttons doesnt at all. I pretty much have to double click each time to make a button register. It switches my profiles just fine … but just takes lots of clicks to register.

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setup(5, GPIO.IN, pull_up_down=GPIO.PUD_UP)
GPIO.setup(6, GPIO.IN, pull_up_down=GPIO.PUD_UP)

tries = 0

while (tries < 200000):
    if GPIO.input(6):
        print("Open 6")
    else:
        print("Close 6")
    if GPIO.input(5):
        print("Open 5")
    else:
        print ("Close 5")
    time.sleep(0.5)
    tries = tries + 1

@istepgueu Will take a look through this now, but i already have a 1k resistor between pins 5/6 and the respective button. Hopefully something else comes up here.

Yes my problem seems a bit opposite of what was posted in your link. I dont have any erroneous button presses, it just takes a few clicks until MMM-Buttons registers the click. You button.py registers every click instantly. So must be something in the buttons code?

@Mar @istepgueu The library (onoff) I am currently using does not directly allow configuring pull up and pull down resistors, and I was not able to make it consistently work (see Readme).

Therefore I myself made use of the “right” pins for my setup, as the readme says:

The defaults can be seen in Table 6-31 on pages 102 and 103 of the BCM2835 ARM Peripherals documentation.

There I simply used buttons with the correct default pull-up/pull-down resistor configuration (second column of that table), and I wanted a few pins close together on the board, so I chose GPIO 22,23,24 and 25 (connected 4 buttons), since they all have the default of a low input.
