1. eufy Rauchmelder E10
The Eufy Smoke Sensor E10 3-Pack provides comprehensive smoke and gas detection coverage across multiple floors of your home. This set includes three compact smoke detectors designed for simultaneous monitoring of key areas such as kitchens, attics, and laundry rooms. Each unit measures approximately 10 cm in diameter with a height of 3.5 cm, comparable in size to a standard coaster for discreet placement. The smoke detectors operate on a non-replaceable battery with an estimated lifespan of five years, after which the entire unit requires replacement.
