This device can be used to alert a member of the household that his or her presence is required in the area where the pulse has been made or in case of emergency with persons of reduced mobility, which is the most useful function.
It is powered by a 3V CR1632 button cell battery, which can be easily replaced when it is exhausted. Its dimensions are 3.6 x 3.6 x 1.15 cm for a total weight of 200 gr. It is made of fireproof plastic and is only available in a white finish. It features 2.4 GHz WiFi based on the Zigbee Protocol and is compatible with both Android above version 4.0 and iOS above version 7.
The device supports three different keystroke types: short press, double press and long press. Each of these modes can be assigned to an action related to home automation. For example, one of the pulses can be associated with making a call to an emergency number or to a pre-set number, but the possibilities are practically infinite.
