ConnectPort X2e SEP 2.0 Compliant Home Energy Gateway with Zigbee Connectivity

Digi International announced the “ConnectPort X2e for Smart Energy”, a Linux-based Home Energy Gateway with Zigbee connectivity based on Freescale Home Energy Gateway Reference Platform powered by Freescale i.MX28 processor.

The “ConnectPort X2e for Smart Energy” is upgradable to comply with the new Smart Energy 2.0 Profile (SEP 2.0)  and  enables ZigBee devices on a Home Area Network (HAN) to communicate with an energy service provider.

The new gateway is a low-cost, enhanced version (hence the “e” in X2e)  of Digi’s ZigBee Smart Energy Gateways.  The device connects ZigBee Smart Energy devices from a Home Area Network (HAN) to an energy service provider via broadband. It supports over-the-air updates of connected Smart Energy devices, making it easier for utilities and application partners to establish and maintain large Smart Energy device deployments.

The company offers two models namely:

  • ConnectPort X2e, ZigBee SE Coordinator for stand-alone Smart Energy networks that do not have smart meters.
  • ConnectPort X2e, ZigBee SE Router to connect and read the smart metering system which has been installed at the site.

End-users can use Digi’s Smartlee application for iPhone and Android and/or utility-hosted websites to monitor and even control their electricity consumption in real-time.

The ConnectPort X2e uses the iDigi Device Cloud service to manage connectivity, configuration and software upgrades as well as application integration enabling  the Home Area Network (HAN) and Smart Energy devices, such as Programmable  Communicating Thermostat (PCT) and In-Home Display products from other manufacturers.
