This module is a part of the NetHomeServer. The NexaSmokeDetector communicates with the Nexa wireless smoke detectors, and can trigger an action in NetHomeServer when the alarm is activated. The Item can also trigger the alarm to go off. Note: NetHome may never be used as part of a real fire alarm system, the reliability of the hardware and software is way to low for that kind of application. It may only be used to provide supplementary functions.
