ESP8266 Presence Detection Notification To Mobile via IFTTT

How-To
1

Hi All; I’m building a tiny motion detection sensor using ESP8266-01 and PIR. Please refer to the code below. I registered the device o thinger.io and I added an Endpoint for the event and then trigger an IFTT event etc …all works like charm. The issue is after sometime (random) the device goes offline (thinger.io) and doesnt come back online till I reset it. Note, sometimes work for 30-40minutes others of 8-15min.

I doubt that there is hardware issue; I’m using one of the FT232RL to power the ESP8266 and the sensor. It provides regulated 3.3V and 5V.

I did think about te debug mode and collected some dump - attached to this email.

I’m not experienced with the ESP8266 and Thinger - I hope someone smarter than me can give me some advice.

Code:

#define _DEBUG_
#include <ESP8266WiFi.h>
#include <ThingerWifi.h> 
//#include <ThingerSmartConfig.h>

#define USERNAME "someuser"
#define DEVICE_ID "A001"
#define DEVICE_CREDENTIAL "some_credential"

#define SSID "SomeSSID"
#define SSID_PASSWORD "Some_Password"
int MOTION_SENSOR = 2;

ThingerWifi thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL);
//ThingerSmartConfig thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL);

void pinChanged() {
  thing.call_endpoint("MOTION_SENSOR");
  }
  
void setup() {
  Serial.begin(115200);
  delay(200);
  attachInterrupt(MOTION_SENSOR, pinChanged, RISING);
  thing.add_wifi(SSID, SSID_PASSWORD);

}

void loop() {
  thing.handle();
}

It should be a hardware issue. I think it is not safe to power ESP8266 from FT232RL as it won’t be able to provide enough current during some TX/RX operations, as the 3.3v output is not intended for power supply (it can provide 50mA at most, and the ESP8266 can consume up to 170mA + PIR sensor consumption). So I recommend you to test your setup using a external power supply to avoid burn your FT232RL. This is causing a random behaviour depending on TX/RX consumption, as it is not always the same, depending on the network, signal, etc.

From FT232RL datasheet:

3.3V output from integrated L.D.O. regulator. This pin should be decoupled to ground using a 100nF capacitor. The prime purpose of this pin is to provide the internal 3.3V supply to the USB transceiver cell and the internal 1.5k[ch937] pull up resistor on USBDP. Up to 50mA can be drawn from this pin to power external logic if required. This pin can also be used to supply the FT232R’s VCCIO pin.

After reading the code deeper, I also recommend you to avoid calling the call_endpoint method directly in the interrupt. As interrupts may execute so fast, but call_endpoint is not a cheap operation for a microcontroller. It also may provoke writing to the socket even before the device has logged in or connected, that will provoke unexpected behaviour. I recommend you to update your code to the following one:

#define _DEBUG_
#include <ESP8266WiFi.h>
#include <ThingerWifi.h> 
//#include <ThingerSmartConfig.h>

#define USERNAME "someuser"
#define DEVICE_ID "A001"
#define DEVICE_CREDENTIAL "some_credential"

#define SSID "SomeSSID"
#define SSID_PASSWORD "Some_Password"
int MOTION_SENSOR = 2;

ThingerWifi thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL);
//ThingerSmartConfig thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL);

bool motion_detected = false;
void pinChanged() {
  motion_detected = true;
}
  
void setup() {
  Serial.begin(115200);
  delay(200);
  attachInterrupt(MOTION_SENSOR, pinChanged, RISING);
  thing.add_wifi(SSID, SSID_PASSWORD);

}
void loop() {
  thing.handle();
  if(motion_detected){
    thing.call_endpoint("MOTION_SENSOR");
    motion_detected = false;
  }
}

Other alternative is to read the pin state in the loop, and avoid using the interrupt.

Maybe it solves your problem with the unestability, but anyways, I recommend you to use a external powe supply for this.

Noted well. Thanks for the advice. I will attempt an independent power source with >350mA and regulated 3.3V and post back the results.

5

I agree that sounds smarter as interrupt will take the processor to a new state where all other operates are suspended. Possibly causing the wifi or thing handle to time-out ?

Will re-program the ESP8266 and post the results back.

Kind of you to share your thoughts - thanks for the feedback.

Many Thanks Alvarolb; it seems you got it spot on. It was the interrupt routine taking too long causing this issue. I used your code as is.

Tested it for 2 hours with motion activities every 8 seconds.

Many thanks for the advice.

Great! Glad it worked… :slightly_smiling:

Just one question, what kind of IFTTT events are your calling? Reporting a motion activity every 8 seconds seems quite a lot!

Sorry I was not very clear. My PIR reports 3.3v on motion detection and it stays “ON” for 8 seconds. So can not detect multple motions within 8 seconds frame. It stays “ON” as long as the motion is being detected. Which is why I’m using the RISING edge only. Seems to do the job for me.

Upon motion detection the Thing handler is calling the EndPoint which in turn is communicating with IFTT event. On my iPhone I set the IFFT to send push notification upon Maker event.
For IFTT maker you need to make sure the event name is consistent with Endpoint and the ESP8266 code.

The funny part that it costs me $77AUD to buy a DLink motion detector; now it costs me $5AUD only.
I attached the Thinger config for reference.

It is much more clear now! It makes sense now. Thanks for sharing your configuration :wink:

In the future, it will be possible to send mobile notifications right from the thinger platform, without having to configure IFTTT channels, but in the meantime this is the perfect solution!

Keep us updated about the stability of your setup!

Thanks for the help. I just added an option to activate/de-activate notifications via Thinger. Also can be controlled with “DO Button” from IFTT.

Also working charm. Maybe I should stop making more comments in this thread.

int MOTION_SENSOR = 2;
bool NOTIFICATION = HIGH; // "HIGH" the handle will call endpoint and hence notify user. In the future initialize from cloud
bool MOTION_DETECTED = false;

ThingerWifi thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL);
//ThingerSmartConfig thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL);

void pinChanged() {
  MOTION_DETECTED = true;
}
  
void setup() {
  Serial.begin(115200);
  delay(200);
  attachInterrupt(MOTION_SENSOR, pinChanged, RISING);
  thing.add_wifi(SSID, SSID_PASSWORD);
  thing["notif"] << [](pson& in){
    NOTIFICATION = in;
    };
}
void loop() {
  thing.handle();
  if(MOTION_DETECTED & NOTIFICATION){
    thing.call_endpoint("MOTION_SENSOR");
    MOTION_DETECTED = false;
  }
}

I would improve your sketch by changing the resource notif as the following:

thing["notif"] << inputValue(NOTIFICATION,{
     /* here you could even attach/detach the interruption based on the updated NOTIFICATION
        value, turn off the PIR sensor, etc., but it is not really necessary */
});

This way, when you access your device from the API Explorer, from the Android APP, or from a control widget in the dashboard, you can see the current state of the NOTIFICATION (not always off) value, so you can turn it on and off more easily. Did you tried any of this variants to handle the notification state?

Maybe we can change the topic name to something more representative, as the conversation is evolving, what do you think about “ESP8266 Presence Detection Notification To Mobile via IFTTT”?

12

Taken. Thanks for the advice. Is there is a way to read the NOTIFICATION value from Thinger at boot?
In my code I initialized it to HIGH. But I would like the device to remember the last state and I guess that shouldn’t be maintained in the EPROM.

What do you think?

13

This is a planned feature for thinger.io! At this moment there is no other alternative than using the EEPROM/FLASH, which is so easy to manage. In this case you can use the notif resource to update the EPROOM value.
