    Hello Sir, thanks a lot for sharing. Do u have any idea what happened after I disable the warning button and no more notification, which is fine. When I close the gate and open again, the Disable warning button reset back to enable but unfortunately it does not send anymore notification even the button visibly change back to enable. I press disable and enable manually, the notification runs normal again.

    Make a Homebridge plugin for this and you've got the most awesome thing ever.

    Version Without Notification Feature BELOW ———->>>>>>

    //Code Originally Created By Tyler Winegarner, 2017

    //No anoying notification feature featured in original video

    #include <Blynk.h>
    #define BLYNK_PRINT Serial

    #include <ESP8266WiFi.h>
    #include <BlynkSimpleEsp8266.h>

    char auth[] = "YOUR AUTH HERE";

    // Your WiFi credentials.
    // Set password to "" for open networks.
    char ssid[] = "WIFI USERNAME";
    char pass[] = "WIFI PASSWORD";

    // Select your pin with physical button
    const int doorPin = 2;

    WidgetLCD lcd(V3);

    void setup()
    // Debug console

    Blynk.begin(auth, ssid, pass);

    pinMode(doorPin, INPUT);


    void loop()

    if (digitalRead(doorPin) == HIGH) {
    lcd.print(0,0, "Door Open ");

    } else {
    lcd.print(0,0, "Door Closed");

    How do I disable the notification feature? Can I just remove the component from blink? Do I need to mess with the code?

    Would this be possible with a nodeMCU type board? Would anything have to be changed? How could I make this work for two garage doors?

    Hi, I bought these parts thinking it was all I needed, not realizing it was only the newer parts. Could you put amazon links for the other materials? Thanks

    Does this project work with multiple users/phones?

    By installing this project, i understand we add the capability of opening/closing and checking the status of the garage door BUT does it retain the capability of opening/closing the garage door via the wall switch as well as the garage door remotes?

    does this code work with wemos d1 mini ?

    I built this and it works fine with a continuity tester closing the circuit but after connecting it to the garage door opener it won't. I can jumper the terminals and the door will open and close but it appears the opto isolator might not have enough kick. Any ideas?

    Couple of questions. Can you still use the photon? And do you have to use a perfboard? Could you still use a mini breadboard like in the original project? I had bought most of the stuff for the original project before I saw this update, but this update is what I really want.

    Could this be set up to control 2 garage doors? What would the wiring and code look like?

    Is there a article in Make magazine covering this project more in depth? If so what # magazine. Thanks!

    I already i created this project using particle photon and blynk. But there is no door status monitoring.using these same steps is that possible?

    Great project! Finally got around to trying this out this weekend. At first I had a problem with the device constantly disconnecting in Blynk; it worked but only intermittently with a message constantly popping up with a device disconnected message. Ultimately the fix was to increase the timer interval (from timer.setInterval(10, buttonLedWidget); to timer.setInterval(1000L, buttonLedWidget);). Still need to adjust the warnThreshold from that change and the High/Low warnPin feels backwards to me but works well. Thanks!

    is this possible to use ESP8266 esp-12e then Adafruit 2821 Feather HUZZAH with ESP8266 Wi-Fi if yes what i have to change in the code to work with ESP8266 esp-12e

    Great job man!!
    Is there a particular reason that you picked an Arduino controller instead of a Raspberry Pi 0 W board? I'm asking that because the Raspberry is a cheaper option!

    Nice project!.Planning to make one. – Thanks. Please let me know the soldering iron make you have used in this project. Thanks in advance.

    very cool….i think i am going to see if my 13 yearold wants to learn this stuff, right up his alley.

    Am I the only one that spotted the missing dropping resistor for the optocoupler LED? without that you will kill the optocoupler or the ESP sooner or later.

    Does the board needs to be connected to a pc to keep it connected to the wifi?
