Hallo @Daendaralus,
habe deinen Link hier zu deinem Script auf einem anderen Forum gefunden. Grundsätzlich finde ich dein Script auch sehr interessant. Erlaube mir aber dazu mal ein paar Fragen da ich kein Coder bin: Ich nutze Fritz Dect 301 und habe diese mit der AVM Integration in Home Assistant eingefügt. Zur Steuerung nutze ich Better Thermostate da ich damit einfach mehrere Thermostate zusammenfügen kann und auch die Fenstererkennung und -steuerung verbinden kann. Aber aktuell stellt Better Thermostate die Regeltemperatur über die Differenz zum Sollwert ein anstatt dies, wie bei anderen Thermostaten (Zigbee, Zwave etc.), über das Offset einzustellen. Daher wird auf dem Display der 301er auch immer eine "falsche" Solltemperatur angezeigt. Wäre es denn möglich mit deinem Script eine solche Offsetsteuerung für ein vorhandenes 301 zu generieren was dann von anderen Anwendungen genutzt werden könnte? Oder ist es eine reine Einzelsteuerung über das Script?
Ich hoffe ich konnte mich halbwegs verständlich ausdrücken. Gerne können wir das auch an anderer Stelle als hier weiter erörtern.
Danke erstmal und hoffentlich bis bald.
Grüße
