the decision$-$making process for purchasing smart home devices involves recognizing the need, conducting information search and evaluation, making the purchase decision, and evaluating post$-$purchase satisfaction. Determinant attributes that differentiate smart home devices from Amazon, Google, and Apple include integration and compatibility, voice assistant and AI capabilities, ecosystem and app support, and design and aesthetics. Factors such as privacy and security concerns, compatibility issues, reliability, and cost can impact consumers' propensity to buy. Post$-$purchase cognitive dissonance may arise, but sellers can address it by providing support, communicating product benefits, encouraging positive reviews, and offering return policies. In a competitive market, marketing mix factors such as product innovation, pricing, promotion, and distribution are crucial. A new product can focus on unique features, integration, privacy, user experience, pricing, customer support, differentiation, and early adopter incentives to compete effectively. By considering these elements, businesses can successfully navigate the smart home device market and meet consumer needs.
