NXP’s In-Home Energy Displays help track and manage energy consumption and costs. These displays are typically user-interactive and allow the operator to access real-time up-to-date information. Therefore, the handheld display must have a processor for system management, wireless connectivity to access consumption and cost data via multiple communication protocols.
