Free and compatible with all modern devices, the Comelit Simple App is designed specifically for the installation of art. 1406 for connected building systems, and allows you to receive calls from the outdoor entrance panel wherever you are, open gates or doors and switch on lights. Easy to configure using the QR codes provided; install the app with the first scan and configure the app with the second scan. The app uses push notifications, which means that it is only activated when a call is received, thus saving energy and data. Install a Comelit system and enjoy all the benefits of a portable door entry monitor.
