Garage Door Detectors

@istepgueu said in Garage Door Detectors:

I already installed physical sensor like the picture in the first post.
I can connect it to the GPIO.

The whole hardware part is already done. It is currently running on an arduino but I would like to move it on the magic mirror (and therefore have a module that reads if the contact is open or closed on a pin of the GPIO).

Then that sir is a doable thing!!!

@istepgueu Please share your findings and code if possible. I’m looking into modding my garage door and using project that I mentioned above. Would be interested in getting info on sensors hookup and anything that you find while building it.

[cowboysdude]

Yes please share! :) Funny things about modules… they can be modified to work with other things!

I have a Chamberlain myq which will send a signal over wifi determining if my garage is open or closed to what i’m guessing is their server. Similar to Nest for the temperature. I wonder if there’s an API I can use to display the status.

@ooom416354 this may get you started http://docs.unofficialliftmastermyq.apiary.io

@morozgrafix wow. this is a great find, thanks!

Hello.

Here is my current “installation”.

My 2 door sensors send 1 or 0 if there is contact.

Depending on the result, LEDs 1 and 2 light up red or green.

What I would like is to replace the leds with a logo on the mirror.
(I have a door on the street side and a door on the garden side which explains the logos)

Here is the code of my Arduino project.

#include   

const int  C_buttonPin = 12; // Door 1 
const int  H_buttonPin = 13; // Door 2

const int ledsPin = 2;
const int nombreLeds = 2;
const int intervalleTemps = 200;
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(nombreLeds, ledsPin);

int C_buttonState = 0;         // Etat actuel Door 1
int H_buttonState = 0;         // Etat actuel Door 2

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
  // make the pushbutton's pin an input:
  pinMode(12, INPUT_PULLUP);
  pinMode(13, INPUT_PULLUP);
  pixels.begin();
  pixels.show();
}

// the loop routine runs over and over again forever:
void loop() {

 int sensorValC = digitalRead(12); Serial.println(sensorValC);
 int sensorValH = digitalRead(13); Serial.println(sensorValH);

  
if (sensorValC == 1) 
{
pixels.setPixelColor(0, 255,0,0);  
}
else
{
pixels.setPixelColor(0, 124,252,0);
}

if (sensorValH == 1) 
{
pixels.setPixelColor(1, 255,0,0); 
}
else
{
pixels.setPixelColor(1, 124,252,0); 
}



pixels.show();
delay(intervalleTemps);

}

Ho and sorry for my bad english (i’m from Belgium)

@istepgueu thanks for the write up. I was just looking for similar sensors for my garage.

[istepgueu]

I think it’s possible to adapt MMM-Buttons for my project.
https://github.com/Jopyth/MMM-Buttons

I connected my 1 garage sensor to PIN 25 and GND
I connected my 2 garage sensor to PIN 24 and GND
How can i show a png file when sensor 1 (or 2) is “pressed” ?

Thanks a lot ;-)

[istepgueu]

Yes !

I have successfuly installed MMM-buttons and connect my first magnetic sensor to pin24

When contact is ON, nothing happen.
When contact is OFF, I have the notification message and the RPI Shutdown.

Now I’m a bit stuck for the rest.
I do not see how to display images in a specific place in the mirror.

Here is the working code :

{
    module: 'MMM-Buttons',
    config: {
        buttons: [

{
                pin: 24,
                name: "power",
                longPress: {
                    title: "Power off",
                    message: "Keep pressed for 3 seconds to shut down",
                    imageFA: "power-off",
                    notification: "REMOTE_ACTION",
                    payload: {action: "SHUTDOWN"}
                },
                shortPress: undefined
            }

        ]
    }
},
