Verarbeitung von CaCrosse Sensoren TX29DTH

DerUwe

Hallo

Nach langem basteln habe ich nun meine CaLrosse Sensoren im Haus in den IOBroker geschafft und möchte Euch meine Variante der Implementierung nicht vorenthalten.

Ich würde mich über konstruktive Kritik und Anregungen sowie Idees wie man es besser machen könnte sehr freuen!

Wie funktioniert es:

Aufgrund fehlendem Wissen wie man serialport in iobroker.javascript nutzt, habe ich einen Node-Red Sketch erstellt. Dieser holt die Daten von der Seriellen Schnittstelle und speichert den String in javascript.0.Jeelink_RAW_data

Ein Javascript hat eine subscription auf diesen tag und wird bei Änderung entsprichend getriggert.

Das die Sensoren bei Batteriewechsel eine neue Addresse nutzen, wollte ich die Addressvergabe flexibel über die VIS managen. Daher nutzt das Script eine Struktur im iobroker für das Mapping.

btw: Das Script erstellt aufgrund des Arrays

var defrooms = ["Schlafzimmer","Dachboden","Keller","Terrasse","Garten","Wintergarten"];

Alle Variablen im iobroker selbstständig.

Sketchcode:

Für den Import in Nodered:

! [ { "id": "287186cc.30fe8a", "type": "serial in", "z": "2e8e9763.fece38", "name": "", "serial": "78ea7747.d23468", "x": 143, "y": 103, "wires": [ [ "1ed58d03.aa454b", "9e43317c.42e5e" ] ] }, { "id": "9e43317c.42e5e", "type": "debug", "z": "2e8e9763.fece38", "name": "Serial In Debug", "active": false, "complete": "payload", "x": 416, "y": 171, "wires": [] }, { "id": "26c364ca.e1767c", "type": "comment", "z": "2e8e9763.fece38", "name": "RFM12 Inbound", "info": "", "x": 134, "y": 55, "wires": [] }, { "id": "1ed58d03.aa454b", "type": "ioBroker out", "z": "2e8e9763.fece38", "name": "Jeelink Raw data", "topic": "javascript.0.Jeelink_RAW_data", "ack": "true", "autoCreate": "true", "x": 420.5, "y": 102, "wires": [] }, { "id": "78ea7747.d23468", "type": "serial-port", "serialport": "/dev/ttyUSB0", "serialbaud": "57600", "databits": 8, "parity": "none", "stopbits": 1, "newline": "\\r\\n" } ] !

Im Javascript Adapter habe ich dann ein script geschrieben das die Auswertung und speicherung vornimmt:

Für den Import in Javascript:

Über welche HW kommen die RawDaten rein?

Serial port im Javasciprt => einfach in der Konfiguration von JS-adapter, unter npm module "serialport" eintragen.

Und dann

var SerialPort = require("serialport");
var port = new SerialPort("/dev/ttyUSB0", {
  baudRate: 57600
});
port.on('data', function (data) {
  // hier sind die Befehle
  console.log('Data: ' + data.toString());
});
port.on('open', function() {
  console.log('Connected');
});
port.on('error', function(err) {
  console.log('Error: ', err.message);
})
// close port if the script stopped (to be able to open it again)
onStop(function (callback) {
    if (port && port.isOpen()) {
	port.close();
   }
   callback();
});

Es gibt doch einen LaCrosse Adapter….[emoji848]

Was kann deine Lösung besser!?

Würde mich sehr interessieren, da ich selbst inzwischen 9 TX 29 DTH-IT Sensoren mit dem Adapter verarbeite

Läuft der mit einem Jeelink oder über die CCU?

~~@Bluefox:~~

hmmm,…. so einfach soll das gehen?....

simpixo

Ich habe diesen mit dem Jeelink am laufen…. aber wird leider im Moment nicht weiter entwickelt [emoji53]

DerUwe

Cool!

Serialport in javascript läuft. Wieder ein Punkt von meiner Liste checked.

bald kann ich Nodered abschalten :-: Wieder 30MB mehr RAM auf dem raspi…

@simpixo: Kannst du kurz erklären wie du den jeelink ans laufen bekommen hast?

Dann gucke ich mir den auch mal an.

Bluefox

> Über welche HW kommen die RawDaten rein?
??

RFLink, CUL, selbstgebastelt?

DerUwe

Das ist ein Selbstbastel jeelink Clone.

Ein Arduino Nano aus China für ein paar Eur + ein RF12B

und die aktuelle LaCrosseITPlusReader Version

#define PROGNAME         "LaCrosseITPlusReader"
#define PROGVERS         "10.1q"

Das Ganze in einen Schrumpfschlauch verpackt

DerUwe

@simpixo:

Wenn das der Adapter vom KleinenDrachen ist, der speichert die Sensordaten unter seiner ID ab, richtig?

Also sowas wie Lacrosse_65_xxxx

Das wollte ich ja nicht!

Wenn ich die Batterien wechsel, will ich nicht immer das Projekt umbauen. Deshalb kann ich jetzt über die VIS den Räumen die neue Addresse mitteilen.

DerUwe

Hier mal die version 2 vom Script, die den Nodered Aufsatz überflüssig macht!

Dank an den blauen Fuchs

iobroker bringt mich noch dazu, das ich javascript auch noch gut finde…

Bzgl CUL:

Den habe ich auch noch am alten FHEM Aufsatz laufen, weil ich den CUL Adapter nicht ans laufen gebracht habe.

@Bluefox: Hast du eine Idee ob der adapter laufen müsste oder ist der veraltet / unbrauchbar?

Der CUL läuft unter /dev/ttyAMA0 auf 9600. Wenn ich den CUL-Adapter konfiguriere sagt er immer er will eine Zahl und nicht 9600… ?? :?

Der aktuelle Adapter läuft nicht - es wird gerade ein neuer entwickelt siehe diesen Thread

Jo, welche Firmware kommt auf den Nano drauf?

Richtig cool wäre wenn der Adapter den CC1101 auf ook stellen und die FS20 Geräte steuern könnte!

@simpixo:

Wenn das der Adapter vom KleinenDrachen ist, der speichert die Sensordaten unter seiner ID ab, richtig?

Also sowas wie Lacrosse_65_xxxx

Das wollte ich ja nicht!

Wenn ich die Batterien wechsel, will ich nicht immer das Projekt umbauen. Deshalb kann ich jetzt über die VIS den Räumen die neue Addresse mitteilen. `

Ja Beim Batteriewechsel muss ich auch die ID in meinen Script ändern, aber nur an einer Stelle!

Da historisiere ich auch die ganzen Daten! Das LaCrosse Objekt interessiert mich in der Hinsicht ja nicht! Also ist es fast genauso wie bei dir! Ich weise sozusagen die ID einem Raum zu [emoji1360]
