The problem can be articulated as follows: "Users of conventional hot water shower heaters often face the hassle of manually setting and adjusting the temperature, which sometimes requires them to wake up early or wait for the water to heat up before taking a shower. Our solution seeks to deliver a more convenient and efficient experience by enabling users to control their shower water heaters remotely, thereby saving time and enhancing comfort." The MVP may consist of: "Our MVP will feature a user-friendly app interface, along with straightforward hardware that can be connected to existing shower heaters. The app will include essential functions such as turning the heater on and off, adjusting the temperature, and monitoring energy usage. Additionally, a timer feature can be added to let users schedule heating times."
