Zwei Fehler am Gerät gefunden. Einzonen-Boxen als Doppelzone erkannt: Manche senden den langen Datensatz einer Zweizonen-Box mit, füllen den zweiten Block aber mit Nullen. Die Nutzlastlänge allein taugt deshalb nicht als Kriterium. Als zweizonig gilt jetzt nur, wo dieser Block überhaupt Inhalt hat, und in den Geräteeinstellungen lässt sich die Erkennung auf "Eine Zone" oder "Zwei Zonen" festnageln. Einschalten reagierte nicht: Ein/Aus und Betriebsart schicken den kompletten Einstellungsblock, der mit dem langen Datensatz auf 31 Byte kommt. Ohne ausgehandelte MTU nimmt BLE aber nur 20 Nutzbytes je Schreibvorgang an, der Rest wurde stillschweigend verworfen. Die Solltemperatur ging als kurzes Paket durch, alles Längere nicht. Lange Pakete werden jetzt anhand von maximumWriteValueLength aufgeteilt und versetzt geschrieben; die Statusabfrage danach wartet entsprechend länger. Aus dem kurzen Datensatz ist der Befehl übrigens genau 20 Byte groß und hätte gerade noch gepasst - deshalb trat es nur an dieser Box auf. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
