Installation ZBT-2 an Home Assistant Yellow

Installation, HW & HA-OS
1

Hallo Zusammen,

ich hänge schon seit einigen Tagen an der Installation der ZBT-2 ZigBee Antenne.

Zum Hintergrund: Ich will meinen Home Assistant Yellow mit einer reichweitenstärkeren Antenne ausrüsten. Daher die Wahl der ZBT-2 die ja von Nabu Casa vertrieben wird. Nach dem Verbinden mit USB erscheint der Stick auch in Home Assistant unter “Geräte & Dienste”. Sobald ich ihn aber hinzufügen möchte, erscheint die Fehlermeldung “Die Installation des Zigbee-Firmware ist fehlgeschlagen.” Das Protokoll habe ich unten eingefügt.

Dabei ist es egal, welche Variante ich wäre (ZHA oder anderes), die Fehlermeldung ist die gleiche. Ich habe bisher verschiedene USB Ports ausprobiert und das System mehrfach neu gestartet.

Per “Device Toolbox” ( Home Assistant Connect ZBT-2 – Device Toolbox ) kann ich über den PC auf den Stick zugreifen. Die aktuellste Zigbee-Version habe ich so bereits installiert.

Leider weiß ich aktuell echt nicht mehr weiter und hoffe, es gibt hier in der Runde noch Ideen.

Hier das Protokoll:

Möchtest du einen Stick migrieren?

3

Nein, ich möchte die aktuell auf dem ZHA-Modul des Yellow laufende Zigbee-Installation auf den ZHA-2 migrieren. Wobei auch eine reine Neu-Inbetriebnahme des ZHA-2 (ohne Migration) scheitert.

Nach dieser Anleitung?

Ja, genau so. Beim Wechsel von Schritt 4 auf Schritt 5 erscheint die Fehlermeldung.

Die aktuelle Firmware, hast Du bereits aufgespielt?

Edit:
Aktuell wäre:
Firmware: EmberZNet Zigbee 7.5.1.0

Gruß Osorkon

7

Am Wochenende habe ich die über die Toolbox aktualisiert, ich glaube, das war die 7.5.0.0. Das checke ich mal heute Abend

8

So, neueste Version war bereits drauf.

Leider immer noch das gleiche Fehlerbild

9

Habe mir mal die Fehlermeldung genauer angeschaut. Es scheint so, dass immer wieder die Verbindung zum ZBT-2 abreist.

Du hast nicht zufällig ZigBee2MQTT parallel am Start? Oder der OTBR, der auf den ZBT- zugreift?

Hast Du auch schon mal versucht ZHA mit dem bestehenden Adapter zu deaktivieren, bevor Du den ZBT-2 als ZigBee Koordinator einrichtest?

Gruß Osorkon

Ich hatte Zigbee2MQTT einmal testweise installiert, danach aber wieder entfernt. OTBR läuft nciht.
Für Zigbee und Threat benutze ich die Build-In Varianten des Yellow. Habe bei deaktiviert, leider weiterhin das gleiche Fehlerbild.
Ein Update auf die neuste HA Version heute hat ebenfalls ncihts gebracht.

Ich bin grade echt überfragt… :frowning:

Hier noch mal ein Update. Ich habe mir testweise den Sonoff MG24 ZigBee Stick besorgt. Wir korrekt erkannt, aber auch hier scheint mir ein Verbindung-Problem vorzulegen. Anbei des Protokoll auf dem Sonoff Flasher:
