The Link-S² IoT Smart Switch is a Wi-Fi connectable indoor wall switch that incorporates an analog switch (twin-circuit), a motion sensor, and a NetSWITCH®-compatible circuit board. Until now, in order to make lighting "smart", it was necessary to replace the lighting itself with smart lighting from a specific manufacturer, but the main feature of Link-S² is how it enables the use of existing lighting as smart lighting simply by replacing existing wall switches with Link-S² units. My home is a second-hand apartment in Minato Ward, Tokyo, and when I had an electrical contractor come to change the existing wall switches over to Link-S² switches, it was a simple job that took less than a day to install a total of 11 units.

Since the installation, I have been turning the lighting on and off using the dedicated smartphone application, as well as via voice operation that links with voice assistants (Amazon Echo, Google Home). When I'm at home, for example, if I think I need more light while cooking, I don't need to go through the process of washing my hands and operating the switch. All I need do is say "Alexa, turn on the kitchen lights" for more brightness, and I can do something similar when adjusting the light when reading and in that way freely control the lights in the house by having them linked, which is both user-friendly and very convenient. It is also extremely convenient because you can use the smartphone application when you are out of the house to check whether you forgot to turn the lights off, or to turn them on in advance before you return home. Another noteworthy point is how the system also contributes to savings on power bills, as the user can see the amount of power consumed by each light displayed on the application's screen. There was great merit in installing Link-S² and making my lighting part of the IoT, and I feel that it was not just the convenience, but also the amenity of being able to create a comfortable space according to my own will. Furthermore, the motion sensors detect human movement, and in addition to automatically turning the lights on, also have an "Observer Function" that enables observation of the family lifestyle from a distant location or when the user is away from home, so this can see use in a new kind of security service leveraging IoT smart switches to play a role in keeping families safe and secure.
