Meet the FIBARO Smoke Sensor: a Z-Wave wireless smoke sensor that alerts you when you need to pay attention to potential issues in your property. This elegant device has a minimalistic design and uses a multi-color RGB LED diode and built-in sound siren to get your attention. The device can also detect high temperature to alert you even if there is not enough smoke.
You can connect the sensor to an alarm hub to do more with it. Sensitivity settings can be modified easily. It has a built-in tester as well. You can find out more about it here.
