These 4 starter kits all consist of one or more sensors and 1 x Gateway with power supply. Data from the connected sensors is transmitted wirelessly and captured by the Gateway device that's connected to the home router or internet connection. From there the data is forwarded to your iOS or Android mobile phone.
This mobile alarm system can be extended to a complete house monitoring system. It is possible to connect up to 50 wireless sensors. New types of sensors are constantly being developed and thus the kit can be expanded almost endlessly. The installation of each new sensor is quite simple. Data and history are updated on your phone through the internet. If you have entered a limit, such as min. or max. temperature, you will receive a Push-notification on your phone the moment it is reached.
