Piezo Node is not visible in HASS latest Version

DuckY1987

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.

/**

MySensors RoomSensor with piezo alarm for audio feedback, like weather alarm when there's a huricane alarm.
The alarm is just a standard alarm in your Home Automation controller.
Version 1.0
Created 25-10-2015
release date 25-10-2015
Author by Theo
Parts used:
- Arduino ProMini 3.3V
- 3V Piezo buzzer (is actually surprisingly loud for such a tiny PIEZO), You can greatly improve on the volume by wrapping a paper tube around the piezo

Hi!

Please edit your post and put the code within code block markdown, ie three backticks, newline, code, newline, three backticks. It's hard to read otherwise.

Also, if you can capture a debug level log from home assistant after start, and post that, it would be great. Keep all mysensors related lines. See https://home-assistant.io/components/logger/ for how to set log level, using logger component.

Eg add this to your config:

logger:
  default: info
  logs:
    mysensors.mysensors: debug
    homeassistant.components.mysensors: debug

Please also post your home assistant config for mysensors.

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.

martinhjelmare

You need to send at least one initial value of the sensor to home assistant, to have the sensor added to home assistant. Also feedback the new value to home assistant in the receive function when a state change occurs.

DuckY1987

@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.

DuckY1987

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?

DuckY1987

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?

martinhjelmare

Yes, like that, for both cases.

DuckY1987

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?

martinhjelmare

No problem, glad to hear about user stories.

Can you explain a bit more, what you mean with IR receive via dev panel? IR receive is a sensor type, right? It should be possible already to update any states in the states dev panel. Maybe I'm not following completely?

Contributing in the form of feedback on what works and don't work is very appreciated. If you want to try Python, pull request for bug fixes or new features is also welcome. Thanks!
