PCgo + PC MagazinSingle testReleaseJuly 2025

Emergency lighting, a control LED that can be deactivated and monitoring of the degree of contamination: the second-generation Homematic IP smoke detector impresses with features that many other detectors lack. In combination with solid workmanship and Q-label certification, this justifies the price of just under 60 euros.
