The new SUPERVISOR app allows you to control your smart buildings from smartphones and tablets quickly and intuitively, both when you are inside them and remotely, thanks to the integration with the supervision webservers and the Domotica Labs cloud platform. Do you have a KNX or MyHOME home automation system, or a technological system based on one or more of the numerous protocols with which we are compatible? Have your trusted installer install and configure one of our supervision webservers - IKON SERVER or PIKO - and take complete control of it thanks to this app. SUPERVISOR allows you to simultaneously manage more than one home automation system, thanks to the possibility of storing the access data of multiple web servers; the app automatically establishes the best connection (whether local via WIFI or remotely) based on where you are. Thanks to integration with the Domotica Labs cloud platform, SUPERVISOR allows access to the various systems without any intervention on the internet router. Furthermore, it is possible to control the most frequently used functions directly from the main screen of the app, without necessarily having to connect to the system itself. SUPERVISOR is also an indispensable tool for installers and system integrators, who through this app can check the correct functioning status of all the home automation systems they are responsible for in terms of maintenance, anticipating their customers' support requests, and offering an cutting-edge service saving time and optimizing travel.
