Link Essential is the new connectivity bridge in the Somfy Home Alarm Security System series. It is the heart of the network and enables the accessories to work together as a system. Link Essential maintains a secure connection to the internet via Wi-Fi, enabling users to check and control the system's status while on the move. “The look is low-interference and blends well into home environments,” praised the jury. The only visible trace of technology is the hidden LED on the top. The opening mechanism allows for convenient installation and maintenance of the bridge.
