Verwendung von MQTT, um Ihr Smarthome zu informieren, dass ein Alarm ausgelöst wurde



Diskutieren Sie diesen Artikel im INSTAR Forum

Q: Ich habe Ihren Leitfaden zur Verwendung des INSTAR (HTTP)-Alarmservers gefunden. Wäre es nicht sinnvoller, diese Ereignisse über den MQTT-Dienst zu veröffentlichen, den jede Full-HD-Kamera bietet? Auf diese Weise könnte ich sicher sein, dass jedes Alarmereignis von meinem Smarthome-System registriert wird.

A: Alle Alarmereignisse, die vom INSTAR HTTP Alarmserver veröffentlicht werden sind jetzt auch über den MQTT-Service erhältlich! Das entsprechende MQTT-Topic ist:

alarm/triggered

Sie müssen lediglich ein Abonnement zum Status-Topic hinzufügen, und Sie erhalten Updates über Alarmereignisse sowie darüber, welcher Dienst den Alarm ausgelöst hat:

Angehängte Alarm Trigger

  • Alarmbereich Bereich 1 ausgelöst: 1
  • Alarmbereich Bereich 2 ausgelöst: 2
  • Alarmbereich Bereich 3 ausgelöst: 3
  • Alarmbereich Bereich 4 ausgelöst: 4
  • Alarmeingang / PIR ausgelöst: 5
  • Audioalarm ausgelöst: 6
  • PIR & Bereich 1 ausgelöst (gekoppelt): 7
  • PIR & Bereich 2 ausgelöst (gekoppelt): 8
  • PIR & Bereich 3 ausgelöst (gekoppelt): 9
  • PIR & Bereich 4 ausgelöst (gekoppelt): 10

Im folgenden Beispiel fügte ich die erforderliche Subskription zu einen Node-RED Flow hinzu und übersetzte die Nachricht 1-10 in etwas, das für Menschen besser lesbar ist:

INSTAR MQTT Alarmserver

Sie können nun mit dem Hinzufügen dieser Status Ausgabe zu Ihrem Node-RED Dashboard fortfahren und diese danach auch mit Aktionen verknüpfen, die Node-RED bei jeder Aktualisierung eines Alarmauslösers auslösen soll:

Unten finden Sie den vollständigen Node-RED Flow, den Sie in Node-RED importieren können:
