Node.js Script in iobroker integrieren

[UncleSam]

@rettroo Du hast das Skript nicht genau so übernommen sondern noch Anpassungen gemacht. Kannst du bitte deine Version des Skriptes hier posten - sonst muss ich raten.

Und wenn wir schon beim Raten sind: dir fehlen Anführungszeichen.

 * When an event is received, it forwards it to the MQTT broker so other systems
 * can received those events. This behavior is very generic, users need to listen
 * to those MQTT messages and create their own integrations using something like
 * node-red for instance.
 *
 * In time this could be used to create a more user-friendly integration in home assistant,

@rettroo sagte in Node.js Script in iobroker integrieren:

this.dahua_host = 10.0.0.11;
this.dahua_username = admin;
this.dahua_password = admin123;
this.mqtt_broker_host = 10.0.0.10;

Wie ich gesagt habe: dir fehlen Anführungszeichen. Strings müssen immer mit Anführungszeichen geschrieben werden. zB: this.dahua_host = "10.0.0.11"; Und leere Strings natürlich auch!

[UncleSam]

@rettroo Jawohl, alles richtig. Das einzige was du wohl noch anpassen musst: alles was console.<irgendwas>()ist musst du umschreiben nach log(). Denn Konsolen-Logging gibt es keines im JavaScript Adapter.

[rettroo]

@unclesam
Danke, das Script läuft!

[rettroo]

Ich benötige hier bitte noch Unterstützung. Ich bekomme in MQTT folgenden String

{"Data":{"CardNo":"b01xx636","CardType":null,"LocaleTime":"2021-01-28 15:47:08","Method":1,"Name":"OpenDoor","Password":"","ReaderID":"1","RecNo":96,"SnapURL":"","Status":1,"Type":"Entry","UTC":1611848828,"UserID":"2"},"deviceType":"VTO4202F","serialNumber":"6K0xxxxxxx20A0"}

Ich benötige in dem Fall nur die User ID in 0_userdata.0.DahuaUserID

[rettroo]

@UncleSam
Ich habe mir nun was zusammengebastelt.
Der Datenpunkt "serialNumber" wird geschrieben, der "UserID" nicht. Wie gebe ich den richtig an, da er ja nochmal in "Data" verschachtelt ist.

on({id: "mqtt.0.DahuaVTO.AccessControl.Event", change: "any"}, function (obj) { ParseCommand(obj); });
 
function ParseCommand(obj) {
 
  let value = obj.state.val;

  let serialNumber = "";
  let UserID = "";
 
   
  try { 
    obj = JSON.parse(value);
  
    serialNumber = obj.serialNumber;
    UserID = obj.UserID;
   
    setState('0_userdata.0.serialNumber', (serialNumber));
    setState('0_userdata.0.UserID', (UserID));
    
  } catch (e) {
    return;
  }
}

Sonst sauber programmiert?

[UncleSam]

@rettroo sagte in Node.js Script in iobroker integrieren:

Wie gebe ich den richtig an, da er ja nochmal in "Data" verschachtelt ist.

Einfach mit einem Punkt dazwischen: obj.Data.UserID

[pseudoreal]

könntest Du bitte eine Anleitung für "Dummies" erstellen? Was genau muss zu erst installiert werden? Danke

[rettroo]

@pseudoreal
Hi, kann ich machen sobald ich alles fertig habe. Die Dahua hängt zur Zeit auch noch nicht an der Tür sondern in meinem Büro

[rettroo]

Hi @unclesam,

das Script hat soweit schon ganz gut funktioniert, nun startet es aber nicht mehr und ich bekomme folgenden Fehler.
Was hat es mit dem MD5 auf sich?

[UncleSam]

@rettroo Hast du das md5 Modul installiert?

const md5 = require('md5');

Sollte eigentlich schief gehen, wenn du md5 nicht installiert hast, was ich etwas komisch finde. Hast du das etwa aus dem Skript gelöscht?

[pseudoreal]

@rettroo
also ich habe jetzt den MQTT server installiert. Das Script in Javascript erstellt und alle Instanzen gestartet. Ich bekomme den Fehler:
(20360) FetchError: request to https://192.168.178.10:443/cgi-bin/magicBox.cgi?action=getSystemInfo failed, reason: unable to verify the first certificate

Unter Instanzen ist jedoch MQTT gelb und auch im Script sebst sind mir einige Zeilen als Fehler unterstrichen - zB const DigestFetch = require('digest-fetch');
md5 und digest-fetch sind aber in der JavaScript instanz aktiviert.

[UncleSam]

@pseudoreal sagte in Node.js Script in iobroker integrieren:

request to https://192.168.178.10:443/cgi-bin/magicBox.cgi?action=getSystemInfo failed, reason: unable to verify the first certificate

Da steht ja die Fehlermeldung. Du machst HTTPS und das Zertifikat ist ungültig. Muss es denn HTTPS sein? Wie du die Zertifikatsüberprüfung ausschaltest, kann ich dir leider auch nicht sagen (ich kenne digest-fetch nicht).

[rettroo]

@pseudoreal

Hi,

wie von @UncleSam angemerkt würde ich das "s" mal weglassen also "http://

MQTT sollte erst grün werden wenn sich das Script mit Dahua verbindet

[pseudoreal]

@rettroo @UncleSam
ok, ich habe das https weggelassen uns nun klappt die Verbindung und ich sehe auch im Script log, wenn sich jemand bewegt (VideoEvent) oder jemand klingelt (Invite).

Jetzt fehlt mir nur noch die Information wie ich diese in iobroker weiterverarbeite, damit mir zB eine WhatsApp geschickt wird. Habe hier schon gesucht, aber leider nichts gefunden - wahrscheinlich falsche Suchbegriffe. Habt ihr irgendwo ein gutes Tutorial, wie man nun mit den Werten in MQTT weiterarbeitet?

@pseudoreal Du füllst Datenpunkte ab und schreibst Skripte, Blocklys oder machst Rules. Das hat dann nichts mehr mit deinem Skript zu tun sondern ist ganz gewöhnliches Skripting in ioBroker.
