Garage Door Detectors

@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.

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.

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 ;-)

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
            }

        ]
    }
},

@istepgueu as far as I understand MMM-Buttons only sends notifications when button is triggered (long or short press). Your sensor is acting as a long button press and you got it working so far. What I think you need is a custom module to display status of your garage door(s) that is capable of accepting notification from MMM-buttons and then changing message displayed (or image) on the MM. One thing to keep in mind (as far as i know) is that MMM-buttons assumes that no buttons are pressed when MM starts, in your case you may need some additional logic to account for times when MM starts when your garage door is opened. @Jopyth is the original creator of MMM-buttons and may have some ideas on how to deal with that.
