Today, millions of consumers are having difficulties buying connected devices for their home, car, office and soon the Metaverse. There is insufficient product information, high upfront costs, lack of concise value proposition and low awareness of product benefits. Manufacturers, installers/service providers, and retailers need to improve the connected device purchase process. Driving consumer awareness and improving consumer access to comprehensive product information will help as well as educating their sales teams on selling these smart products. All will require significant time and capital investments. In addition, trying to find products online is challenging because search engines are not designed to "find" products.
