Home Energy Management Systems  Favorite




Freescale's home energy management systems allow every point of the smart home to be connected and controlled from a central point, enabling power efficiency and energy optimization.

Leveraging the deployment of communications-enabled electricity meters, many applications can be offered to home owners for optimizing overall energy management, and to utility companies as a means of managing the load of their grid and preventing power demand peaks. Freescale's home energy management systems are the interface between the utility-controlled smart grid and energy-consuming in-house objects.

Functions of the Home Energy Management Systems:

  • Collect real-time energy consumption from smart meter and power consumption data from various in-house objects
  • Control activation/deactivation of home appliances
  • Generate dashboard to provide feedback about power usage
  • Provide control menus to control appliances
  • Provide a link to the utility and/or Internet

Target Applications

  • Home Area Network (HAN)
  • Home Energy Gateway
  • Home Automation
