Thanks i will test it today in the evening.

Btw thanks for your great implementation!

i dont know if its in process but an IR receive via the dev panel would be awesome ;-).

Can i shoot you a beer or smth? ;-) or smth from ali?

void incomingMessage(const MyMessage &message)
{
  if (message.type == V_STATUS) {
     // Change sirene state.
     digitalWrite(PIEZO_PIN, message.getBool() ? 1 : 0);
     gw.send(sireneMsg.set(message.getBool() ? 1 : 0));
  }
}

That you mean with receive feedback right?

so smth like:

void setup()
{
#ifdef DEBUG // turn on the Serial monitor if #define DEBUG is uncommented in MyConfig.h (MySensors library)
  Serial.begin( 115200 ); // only debug to serial monitor during development
#endif
  // setup a connection to the MySensor's gateway and request an ID if we do not have one yet.
  gw.begin(incomingMessage);
  gw.sendSketchInfo(SN, SV);
#ifdef DEBUG // Print some debug info
  Serial.println( "Radio is connect right." );
#endif
  // Initialize the digital pin as an output.
  pinMode( PIEZO_PIN, OUTPUT);;
  gw.present(CHILD_ID, S_BINARY);
  gw.send(sireneMsg.set(0));
}

How does the feedback looks like in the receive part?

@martinhjelmare i'm rather new to active nodes, do you have an example or could you edit the code above?

I just used reporting nodes till now, first try with my active one :-).

Didn't find much examples for home-assistant with active nodes, basically it could be a switch sketch either i assume.

Sorry for the late reply, i was a bit absent.

I miss the add entity line, like for the other sensor nodes:

 Adding new devices: <Entity S SP 6 1: None>

Config as usual:

gateways:

• device: '/dev/ttyUSB0'
  persistence_file: '/root/.homeassistant/mysensors/mysensors.json'
  baud_rate: 115200
  debug: true
  persistence: true
  version: '1.5'
  #optimistic: 'true'

Gateway sketch should be 1.6, i want to update soon to 2.1 but as i have plenty of nodes and no OTA intentionally running it will take a while and especially because of a lack of time.

Thats the node sketch:

I changed already a couple Values in the sketch for and backward, but it didn't change anything.

thank you for your help.

Hi there,

i have problems to get my piezo node working, it's my first "active node" which should get triggered on special events like intruder detected "arm_home"

I used the Example Sketch "Alarm" i changed as well already the V_Status to V_Triggered as i saw it is deprecated in HASS.

Mysensor version is still 1.6.

Thanks for help in advance.
