This product belongs to the indoor intelligent home control host and is used to control all IoT terminals in the room. As a well-known brand in the industry, ISSFREE is mainly used in office buildings, public and landmark buildings and villas. First of all, the coordination with the design style of the home and the attachment feeling of the wall are the basic attributes. Secondly, the product design is inspired by the picture frame, which turns the original icy electronic product into a reduced oil painting, and at the same time cleverly combines the display installation method with the modeling level. In addition, this product is ingeniously solved in the same industry products, which have not solved the problem of uneven wall and assembly holes.
