Push button to toggle lights etc

[MasMat]

Can someone help with how to make a toggling switch in Domoticz? I've only used blockly for automation, but I think I might have to do something else to make this work.

Push button sketch:

/**
 * Single button sending transmitter
 * Battery powered by 3V Li-bat
 */

#define MY_DEBUG
#define MY_RADIO_RF24
#define MY_NODE_ID 7

#include <MySensors.h>

int BATTERY_SENSE_PIN = A0;  // select the input pin for the battery sense point
int oldBatteryPcnt = 0;
#define BUTTON_PIN 2   //pin for button

MyMessage msgButton(BUTTON_PIN, V_STATUS);

int sentCounter = 2;
int reading;           // the current reading from the input pin
int previous = HIGH;    // the previous reading from the input pin 

void setup()
{
	pinMode(BUTTON_PIN, INPUT);
	digitalWrite(BUTTON_PIN, HIGH);
  analogReference(INTERNAL);
}

void presentation()
{
  sendSketchInfo("WCNappiBAT", "v08032019");
	present(BUTTON_PIN, S_BINARY, "WC Nappi");
}

void loop()
{
delay(10);
reading = digitalRead(BUTTON_PIN);
  if (reading == LOW && previous == HIGH) {
    previous = reading;
    send(msgButton.set(1));
    sentCounter++;
    delay(50);
    }
  else {
    previous = reading;
    }

if (sentCounter % 5 == 0) {    
  int sensorValue = analogRead(BATTERY_SENSE_PIN);
  // 3.44/1023 = Volts per bit = 0.003363075
  int batteryPcnt = sensorValue / 10;
  float batteryV  = sensorValue * 0.003363075;
  Serial.print("Battery Voltage: ");
  Serial.print(batteryV);
  Serial.print(" V, ");
  Serial.print("Battery percent: ");
  Serial.print(batteryPcnt);
  Serial.println(" %");

  sendBatteryLevel(batteryPcnt);
  }
 
  sleep(0, CHANGE, 0);
}

So the idea is it sends a "1" for every press. That should toggle the lights (controlled by another nodes relay). I had direct communication before but it keeps failing.

Any ideas? Or should I change the sketch? I thought about sending alternate 0 & 1 but then it will not "know" if the light is on or not...

@masmat
Just an idea...
As I recall, Domoticz only responds to changes. So if you send '1' to a switch that are already have '1' status, nothing happens. So I suggest that you first send '1' when the button is pressed. Then after for example 500ms you send '0'. That way the button switch will toggle.
Now - in the switch settings, you can send a ‘Toggle’ command to the node that controls the relay:
http://127.0.0.1:8080/json.htm?type=command&dparam=switchlight&idx=42&switchcmd=Toggle
In your case the ‘idx=42’ should correspond to your relay node.
With this setup, you should be able to toggle your relay with single presses on your button.

@lemme Great, I'll try that. Is that working for you?
Thanks for that json-code bit!

Hi
Yes, it works for me.
You can read more about the json part here:

@lemme said in Push button to toggle lights etc:

http://127.0.0.1:8080/json.htm?type=command&dparam=switchlight&idx=42&switchcmd=Toggle

Works brilliantly!!
