### ⭐⭐⭐⭐⭐ Review
*by H***H on 23 January 2026*

War schnell und problemlos eingerichtet und funktioniert sehr gut. Wichtige Hinweise zur Anleitung: 1) Es existierte bei mir keine LED. Diesen Punkte kann man beim Einrichten überspringen. 2) Der (kleinere) Magnet funktioniert nicht, wenn man ihn mit der langen Seite zum Sensor ausrichtet. Im Gegensatz zur Anleitung musste ich diesen Magneten mit der kurzen Seite in Richtung des Sensors ausrichten. Nachtrag: Ich habe weitere Sensoren bestellt und habe dort nun die LED (siehe 1) gefunden. Sie leuchtet bei mir aber nur sehr schwach und ist deshalb leicht zu übersehen, wenn die Umgebungshelligkeit zu groß ist.
