Which of the following is NOT a common feature of smart HVAC metering devices?

Smart HVAC metering devices are designed to enhance efficiency, facilitate remote management, and support advanced data collection and analysis. A key characteristic that distinguishes these devices is their ability to communicate data in real time, often using wireless systems. This allows for seamless interaction with various technologies and platforms.

The inclusion of both internet connectivity and integration with building management systems (BMS) are common features that enable users to monitor and control HVAC systems remotely, thus optimizing energy use and improving overall system performance.

In contrast, the option highlighting analog-only data output does not align with the advanced capabilities of smart devices. Smart HVAC metering typically employs digital data outputs, allowing for more versatile and rich data communications compared to outdated analog systems. This digital output is essential for supporting the interoperability and complex functionalities that modern HVAC systems require, making it clear that the analog-only output is not a feature associated with smart devices.
