V_UP and V_DOWN are a great suggestion. I use a distance sensor on my garage door for the state. This will let me know when a button push occurred or a remote open was used.

I like that you were able to keep all the electronics inside the gang box. I would like to do something similar for my light switches but I not worked out how to power the components via the mains. Stuffing a charger in the box seems like overkill but it is one solution.

Any other options for powering that node? Any safety issues with having a charge stuffed in a gang box and left inside the drywall?

Thanks in advance

Is that a hardwired smoke detector? I am looking for a hardwired solution that utilizes/runs off the power from a hardwired connection. Not sure if I would have access to 3.3 volts to run the Pro Mini and radio.

If you have the hardware, hook up a sniffer and see what is happening with wireshark at the network layer. I had similar issues and found with the help of the sniffer, my node was having resend/timeout issues even being a couple of feet away. Playing with the channel and data rate, I was able to get a better signal and those st fail messages have stopped. This node is normally in the garage so the interference I had on the default channel was causing issues. Use the sniffer to see what is happening at the network layer.

It forces a status update at a predefined interval.

Alarm.timerRepeat(720, updateState); // update relay status every 2 hrs

Here is one example with a few extras.

// Simple binary switch example 
// Connect button or door/window reed switch between 
// digitial I/O pin 3 (BUTTON_PIN below) and GND.

#include <MySensor.h>
#include <SPI.h>
#include <Bounce2.h>
#include <Time.h>        //http://playground.arduino.cc/Code/Time
#include <TimeAlarms.h>  //http://playground.arduino.cc/Code/Time

MySensor gw;

#define RADIO_ID 12
#define noReeds 5
const int BUTTON_PIN[] = {14, 15, 16, 17, 18};            // Arduino Digital I/O pin for button/reed switch, A0 - A4
boolean reedState[] = {HIGH, HIGH, HIGH, HIGH, HIGH};


Bounce debouncer[noReeds];
MyMessage msg[noReeds];

void setup(){
  Serial.println("Starting setup" );
  gw.begin(NULL, RADIO_ID, true);  //stattc RADIO_ID an enable repeater
  Alarm.delay(250);
  gw.sendSketchInfo("Alarm Pannel", "1.0");
  Alarm.delay(250);
  gw.requestTime(receiveTime);
  // initialize Relays with corresponding buttons
  for (int i = 0; i < noReeds; i++){
    msg[i].sensor = i;			// initialize messages
    msg[i].type = V_TRIPPED;
    debouncer[i] = Bounce();		// initialize debouncer
    debouncer[i].attach(BUTTON_PIN[i]);
    debouncer[i].interval(5);
    // Setup the button
    pinMode(BUTTON_PIN[i],INPUT);
    // Activate internal pull-up
    digitalWrite(BUTTON_PIN[i],HIGH);
    gw.present(i, S_DOOR);		// present sensor to gateway
    Serial.print("setup for switch: ");
    Serial.print(BUTTON_PIN[i]);
    Serial.println(" complete" );
    Alarm.timerRepeat(720, updateState); // update relay status every 2 hrs
    Alarm.delay(250);
  }
  Serial.println("Setup complete" );
}


//  Check if digital input has changed and send in new value
void loop() 
{
  gw.process();
  for (int i = 0; i < noReeds; i++){
    debouncer[i].update();
    // Get the update value
    int value = debouncer[i].read();
    if (value != reedState[i]) {
       // Send in the new value
       gw.send(msg[i].set(value==HIGH ? 1 : 0), false);
       reedState[i] = value;
       Serial.print("updating state for swicth: ");
       Serial.print(BUTTON_PIN[i]);
       Serial.print(" state: ");
       Serial.println(reedState[i]);
    }
  }
}

void updateState(){
  Serial.println("Start state info");
  for (int i = 0; i < noReeds; i++)
  {
      Serial.print("sending update for switch: ");
      Serial.println(BUTTON_PIN[i]);
      gw.present(i, S_DOOR);
      Alarm.delay(250);
      //MyMessage msg(relayPin[pin],V_LIGHT);
      gw.send(msg[i].set(reedState[i]), false); // Send last state from eprom to GW
      Alarm.delay(250);
  }
}

// This is called when a new time value was received
void receiveTime(unsigned long time) {
  setTime(time);
}```

You should check if the value changed and only send updates when true. Something like this.

if (lastTripped != tripped ) {

That usb housing is pretty sweet. A nice shell for a PIR and Temp sensors.

You may look at the node js controller. It has database support. https://github.com/mysensors/Arduino/tree/master/NodeJsController Also check out the controller section of the form. http://forum.mysensors.org/category/3/controllers

Thanks, changing type from 4 to 1 fixed it.
