Hi, I'm building a probably simple project but i cant make it work.
I have one PIR sensor, i need when it detects motion to post this "http://192.168.2.100/cm?cmnd=Power0%20OFF" (its a simple request to turn off a 4ch sonoff/tasmota wifi relay).
I have the uno connect to the network, the PIR is working and i get back message and led notification but i cant post the request.
Please see my code here bellow (its the wifi connect from the library + pir code)
#include <SPI.h>
#include <WiFiNINA.h>
#include "arduino_secrets.h"
///////please enter your sensitive data in the Secret tab/arduino_secrets.h
char ssid[] = SECRET_SSID; // your network SSID (name)
char pass[] = SECRET_PASS; // your network password (use for WPA, or use as key for WEP)
int status = WL_IDLE_STATUS; // the Wifi radio's status
int led = 12; // the pin that the LED is atteched to
int sensor = 2; // the pin that the sensor is atteched to
int state = LOW; // by default, no motion detected
int val = 0; // variable to store the sensor status (value)
WiFiClient client;
void setup() {
pinMode(led, OUTPUT); // initalize LED as an output
pinMode(sensor, INPUT); // initialize sensor as an input
Serial.begin(9600); // initialize serial
//Initialize serial and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
// check for the WiFi module:
if (WiFi.status() == WL_NO_MODULE) {
Serial.println("Communication with WiFi module failed!");
// don't continue
while (true);
}
String fv = WiFi.firmwareVersion();
if (fv < WIFI_FIRMWARE_LATEST_VERSION) {
Serial.println("Please upgrade the firmware");
}
// attempt to connect to Wifi network:
while (status != WL_CONNECTED) {
Serial.print("Attempting to connect to WPA SSID: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network:
status = WiFi.begin(ssid, pass);
// wait 10 seconds for connection:
delay(10000);
}
// you're connected now, so print out the data:
Serial.print("You're connected to the network");
printCurrentNet();
printWifiData();
}
void loop() {
// check the network connection once every 10 seconds:
// delay(10000);
// printCurrentNet();
val = digitalRead(sensor); // read sensor value
if (val == HIGH) { // check if the sensor is HIGH
digitalWrite(led, HIGH); // turn LED ON
delay(100); // delay 100 milliseconds
if (state == LOW) {
Serial.println("Motion detected!");
state = HIGH; // update variable state to HIGH
client.println("POST / http://192.168.2.100/cm?cmnd=Power0%20OFF");
}
}
else {

Serial.println("Motion stopped!");
state = LOW; // update variable state to LOW
}
}
}
void printWifiData() {
// print your board's IP address:

Serial.println(WiFi.SSID());
// print the MAC address of the router you're attached to:

// print the received signal strength:
