ESP8266 mini sends SMS when door opens

How to develop Arduino sketch for ESP8266 mini and magnetic door switch

[ibrahimyusuf]

Thanks Viktor for the time you spent on this project. I got it working in the end but I had to use "esp8266 by esp8266 community v.2.4.2" the exact version you've used. Version 3.x did not work but perhaps I have to give it a go again as there were few minor typos that I had to deal with after that. Will update this in due course. Let me know what later version(s) you've tried since. I am sure you moved on and do some other funky stuff, but hey...Thanks once again.

you should check 10:48 and, thanks for the video

Thank you so much Sir Viktor.
One question. How to use that PLIVO??How do i get the code for that??Again, thank you so much!

Just some helpful advice — many people watch YouTube on their phones. You can’t read a thing because your text is SO small. The screen is over half who’re space with some microscopic text. Zoom to what you’re doing.

Can you give the magnetic switch
Product link for buy

Just the project im looking for, could you please share the code. Thankx.

Thanks for sharing such an Awesome project. Can you please share the code for the same.
Awaiting your earliest response.

I'm a novice, well, I really have no clue on how to build what I want. Was wondering if you could give me some advice or even help me build this little project, if possible. I'd be more than happy to pay you for your time. I'm looking to build a very small or very slim wireless/ wifi window sensor. The smallest possible that's activated by a very small magnet. I need the activation to send a signal straight to my cell phone through my home router (without having to manipulate the settings on my router). I can download "homeassistant" or "mylife" or run a small simple phone app. The intent here is not to adjust any setting on my router. I'd like to get at least 75 - 150ft signal to my router. I have a 3d printer and can make a housing for the battery and board...just wondering if this is possible? Any advice would be much appreciated. Thank you for your help.

Hi sir. So we can use normal esp8266 for this project, right?

[frodemolland]

Hi, possible to use this to get notification when garage door is open?

[MaxGoddur]

Is there a method for sending an SMS text message without using third-party websites as in IFTTT or the one you used. Would like to keep the message sent and received within the LAN.

Hi, here is the code: OpenDetector.ino
#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>
#include "credentials.h"


int switchRead=D1;
bool hasSentMessage = false;


void setup() {
Serial.begin(115200);
pinMode(LED_BUILTIN, OUTPUT);
pinMode(switchRead, INPUT_PULLUP);
connectWifi();
}


void loop() {
if (digitalRead(switchRead) == HIGH) {
digitalWrite(LED_BUILTIN, LOW);
Serial.println("Door Open");
if (!hasSentMessage) {
sendMessage();
}
} else {
Serial.println("Door Closed");
hasSentMessage = false;
}
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
}


void connectWifi() {
WiFi.mode(WIFI_STA);
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
Serial.println("connecting");
while (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
delay(500);
}
Serial.print("connected: ");

digitalWrite(LED_BUILTIN, HIGH);
}


void sendMessage() {

HTTPClient http;
http.addHeader("Content-Type", "application/json");
http.addHeader("Authorization", "Basic " + AUTH_TOKEN);
String postMessage = String("{\"src\":\"") + FROM_TELEPHONE + String("\", \"dst\":\"") + TO_TELEPHONE + String("\", \"text\":\"Main door is OPEN!\"}");
Serial.println(postMessage);
auto httpCode = http.POST(postMessage);
if (httpCode < 0) {
Serial.printf("POST failed, error: %s\n",
}
Serial.println(httpCode);
http.writeToStream(&Serial);
http.end();
hasSentMessage = true;
}

Hi Viktor; What is the name of the USB cable to the ESP 8266 called? Where can I purchase it? Thanks;Mike

[Animace]

Hello, I have used your approach; however, I get 400 Bad Request answer from PLIVO. Do you have an idea what might be wrong? Can you help me out, please?

[ViktorKjartansson]

And here is the credentials.h - you must put your credentials here
#define WIFI_SSID "YourWIFIName"
#define WIFI_PASSWORD "YourWIFIPassword"
#define AUTH_ID
#define AUTH_ID_TOKEN
#define AUTH_TOKEN
#define FROM_TELEPHONE
#define TO_TELEPHONE
#define FINGERPRINT

[arniep]

Is the code available somewhere? Thanks.

Has anyone developed a simple add on current sensor that detects current flow in the door bell wires when the doorbell button is pressed. When it senses the current it will send either a email or text message. Sort of a poor man DIY Ring Door bell for those that already have a camera looking at their front door.

[rootable]

why do you need a breadboard? can't you connect it directly?

[WMCLComputers]

@
Viktor Kjartansson There is in the second line an #include <ESP8266HTTPClient.h> that is never shown in the tutorial who do we get that file or code?

[paulcowley]

sorry Viktor, i see no code, please help. Thankx
