Hallo,
ich bekomme es nicht hin mein erstes Thread Gerät zu verbinden.
Ich habe einen Ikea MYGGSPRAY Bewegungsmelder.
Ich habe die CompanionApp gesynct. Dann hat er versucht das Gerät im Thread Netzwerk von HA anzumelden (Verbindung zum Netzwerk wird geprüft). Dann die Fehlermeldung “Keine Verbindung zum Thread-Netzwerk XY möglich. 
Ich füge mal das LOG vom Openthread ein. Vielleicht sieht jemand mit Erfahrung ob was verkehrt ist?
Danke Sebastian
