Setting up the app is easy to configure the switch and adaptation of the sensors is also very simple and with Deutsche manual a breeze. Among the features I do not need much to write, is indeed already written everything or just ask the dealer. The range of the sensors is impeccable, from the basement to the second floor no problem, and even into the 25 meters distant garden shed. Let's see how the long-term test will be.
Update 03/10/2015 The system is now more than a year in operation with the first batteries. Everything still perfect with no false alarms. In total, there are three plants (of me and my friends) all without problems.
