Sonoff / Tasmota mit OpenHAB 2.4 MQTT

Print Friendly, PDF & Email

In OpenHAB 2.4 wurde die Anbindung an MQTT umgestellt. Es sieht jetzt alle wesentlich strukturierter aus – man muss aber alles in OpenHAB umstellen.

Für die SONOFF Geräte verwende ich die firmware von Theo Arends. Es werden viele Geräte unterstützt und das ganze ist sehr gut dokumentiert. https://github.com/arendst/Sonoff-Tasmota

Hier gehe ichbewusst den Weg über die Text-Dateien und nicht über Paper-UI. Bei jedem Upgrade, setze ich das System neu auf. Mir ist noch nicht klar, wie man die Konfiguration aus PaperUI in ein neues System übertragen kann. Bei den Text-Dateien geht dies aber problemlos.

 

MQTT Bridge definieren

Hier legt man die Anbindung an den MQTT Broker fest. In einigen Beispielen sieht man hier auch die Definition der MQTT Things. Davon rate ich ab, da es zu einem seltsamen Effekt beim Aufbau des Systems kommt: Wenn man eine kleine Änderung an den Things vornimmt, aktualisiert sich das System entweder nicht, oder mit einer langen Verzögerung, da jedes mal die Bridge neu definiert wird. Wenn das separat erfolgt (in zwei Dateien) werden Änderungen an den Things sofort übernommen und sichtbar.

MQTT Things definieren

Zuerst kann man sich die Nachrichten mit MQTT.fx ansehen. Daraus lassen sich die Channels ableiten:

MQTT Items

Hier werden die Channels an ein item gebunden. Die Gruppen könne für die Speicherung (persitance) und die Anzheige (sitempas) verwendet werden.
