Final answer:
Steve's new thermostat is part of the Internet of Things (IoT) trend, which includes internet-connected devices that can be remotely controlled and monitored.
Step-by-step explanation:
The new thermostat installed by Steve that allows him to monitor and adjust the temperature from his phone is a part of the Internet of Things (IoT). IoT refers to the interconnected network of physical devices that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the Internet. Steve's thermostat can be monitored and controlled remotely, showcasing how everyday objects like thermostats can be augmented with such capabilities, much like NASA's Embedded Web Technology (EWT) that enables remote monitoring and control over Internet-connected devices.
