No one wants to work or live in an oven. That’s why we install air conditioners at home or at work to ensure the room temperature stays comfortable enough for us to be productive or to relax. The Smart-Link mobile system lets you do that wirelessly and automatically from anywhere. The system consists of a physical button, chip, and infrared component. The button is controlled by the chip, which connects to the appliance in your house. This retrofitting device can easily make old appliances smart. In the near future of the smart home, old and new appliance can therefore coexist.
