3 Way Switch Turn On//OFF a device with the same command

[estebanhirzfeld]

i Want to Turn On//OFF a device with the same command
example:

"Alexa Turn on D8" D8 now turned On

"Alexa Turn on D8" D8 now turned Off

for that i need to know the actual status from "D8" so when i call the routine, execute the oposite command, i tried with this
but does't work :

`
#ifdef ARDUINO_ARCH_ESP32
#include <WiFi.h>
#else
#include <ESP8266WiFi.h>
#endif

#include <Espalexa.h>

#define D0 4
#define D1 16
#define D2 5
#define D3 14
#define D4 12
#define D5 13
#define D6 15
#define D7 3
#define D8 1

int opo;

const char* ssid = "ssid";
const char* password = "password";

Hi, you've got the right idea!

This should work (also please change the type of opo from int to bool, it is not a number)

void Funcion_D8(uint8_t brightness){
if (brightness){
   opo != opo;
  digitalWrite(D8, opo);
}
  else {
    opo = true; //might need false here instead, depends on if your device turns on if pin is LOW or HIGH
    digitalWrite(D8, opo);
  }
}

Hope it helps :)

The Best Solution was this, now when i say "Alexa Turn Off Light 1" and the Light is already Off, it turns On, Works Great!

/////////////////// Function For Light 1 ///////////////////////////// Light 1 (pin D1)
void Funcion_D1(uint8_t brightness){
     if(brightness){digitalWrite(D1, !digitalRead(D1));}
     else{digitalWrite(D1, !digitalRead(D1));}}
