It does not require an internet connection but a wifi connection so that configurations can be made from mobile. Updates and remote access require an internet connection.

The Smartvest does not have a direct wifi connection. It needs a network cable from the router to the control panel. The control panel is then programmed from a mobile with internet. The external alarm is only sent via the Internet; unfortunately, it is not possible to send an alarm by telephone in Switzerland. I can access the system at any time via the Internet, see which window is open, whether an alarm is pending or switch the system on and off.

In my opinion yes
