Die Installation war kinderleicht. Dank der Bosch Smart Home App war die Einbindung der Sensoren in mein Smart Home-System schnell erledigt. Die Sensoren funktionieren zuverlässig an allen Türen und Fenstern und melden sofort, wenn diese geöffnet oder geschlossen werden. Besonders beeindruckt hat mich die Energieeffizienz. In Kombination mit meinem smarten Thermostat regelt das System automatisch die Heizung herunter, sobald ein Fenster geöffnet wird – das spart nicht nur Energie, sondern auch Heizkosten! Die Kompatibilität mit desertcart Alexa und Google Assistant ist ein großer Pluspunkt. So kann ich die Statusmeldungen der Sensoren auch bequem per Sprachbefehl abrufen. Das Design der Sensoren ist modern und unauffällig, sodass sie sich problemlos in jedes Raumkonzept integrieren lassen. Die Verarbeitung ist wie von Bosch gewohnt hochwertig und langlebig. Fazit: Wer sein Zuhause smarter und energieeffizienter gestalten möchte, sollte sich dieses Tür-/Fensterkontakt-Set von Bosch auf jeden Fall zulegen. Es funktioniert reibungslos und bietet echten Mehrwert.
