Do you have to leave home often or simply want to be sure that your home is safe? It is enough to purchase ACME smart door / window sensor and in your phone you will always see, when the home doors or windows are opened or closed. First of all, the sensor can be fastened on different surfaces: doors, windows, cupboard doors, drawers. If you have children at home – the sensor on medicine cupboard will inform you, if the children decide to check what is inside this cupboard. Also if during being out the rain suddenly starts, the sensors fastened on the windows will allow to see their status in a special mobile app. If some unexpected guests visit your home and try to tear off the sensor – it will immediately send a warning message to your smartphone about attempt to tear off the sensor. Create ACME ecosystem in your home by purchasing other ACME smart home devices. For example, if you have ACME SH2102 smart door / window sensor and ACME SH1101 smart “Wi-Fi” plug, you can create a scenario that upon opening the street-door, the illuminator will switch on (it must be plugged into smart plug.) Or put a setting that upon opening the window in the living-room, the air conditioner switches off automatically. Creation of a scenario is very simple – you only have to use your creativity and imagination. Another advantage of the sensor – very easy fastening. The sensor can be very easily and without much effort fastened with a double-sided tape without affecting the surfaces.
