Hello all,
I need your help.
I will use a motion detector connected to a Wemos D1 Mini (ESP8622) to control a relay device (Devolo or Sonoff).
To bridge blynk to Devolo or Sonoff, I would like to use IFTT with Webhooks.
Here’s the code. Instead an DHT11, a motion detector will be installed.
/***slo-slo-nodemcu09

#define BLYNK_PRINT Serial // Comment this out to disable prints and save space
#include <SPI.h>
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <SimpleTimer.h>
#include <DHT.h>
char auth[] = "dein Blynk Auth Token";
char ssid[] = "dein WLAN-Name";
char pass[] = "dein WLAN-Passwort";
#define DHTPIN 2 // What digital pin we're connected to, d.h. D4 in NodeMCU
// Uncomment whatever type you're using!
#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22, AM2302, AM2321
//#define DHTTYPE DHT21 // DHT 21, AM2301
DHT dht(DHTPIN, DHTTYPE);
SimpleTimer timer;
// This function sends Arduino's up time every second to Virtual Pin (5).
// In the app, Widget's reading frequency should be set to PUSH. This means
// that you define how often to send data to Blynk App.
void sendSensor()
{
int h = dht.readHumidity();
int t = dht.readTemperature(); // or dht.readTemperature(true) for Fahrenheit
if (isnan(h) || isnan(t)) {
Serial.println("Failed to read from DHT sensor!");
return;
}
// You can send any value at any time.
// Please don't send more that 10 values per second.
Blynk.virtualWrite(V5, h);
Blynk.virtualWrite(V6, t);
}
void setup()
{
Serial.begin(9600); // See the connection status in Serial Monitor
Blynk.begin(auth, ssid, pass);
dht.begin();
// Setup a function to be called every second
timer.setInterval(1000L, sendSensor);
}
void loop()
{
Blynk.run(); // Initiates Blynk
timer.run(); // Initiates SimpleTimer
}
So, my question is:
What do I have to do in IFTT, to tell the relay device to power on, if the motion detector changes from 0 to 1 in Blynk?
Best regards
Norman
