CEA Announces New Standard to Help CE Devices Communicate and Manage Power Consumption

At the Consumer Electronics Association (CEA)® Technology & Standards Forum in Seattle today, CEA announced that CEA-2047, CE-Energy Usage Information, has been approved as a new CEA standard. This standard enables consumer electronics devices to communicate how much energy they use to consumers’ computers, mobile devices running smart-energy apps and third-party energy management services.

The Green Button Initiative - an industry-led effort that provides consumers with easy access to their energy usage data - defines how consumers can access a history of their home’s energy usage from their smart meters. However, the initiative does not tell them how much energy a particular device or appliance uses, and getting that information requires either an external metering device or the device itself to make the measurement.

CEA-2047 recognizes that a manufacturer knows how much energy a device will use during operation based on its design. This information can be programmed into the device and used to calculate its energy usage over time, without adding complex metering circuitry. An energy management system or a smart-energy app can then gather the information over the network and present it to consumers on their TVs, PCs, or mobile devices. CEA-2047 is compatible with the Green Button initiative.

CEA-2047 also enables the Internet of Things to be energy-aware. The standard can be used by devices operating on any home network including Wi-Fi, Ethernet, ZigBee, Z-Wave, Bluetooth, and others. And because the standard uses estimation rather than real-time measurement, it is anticipated that almost any communicating device in the home will be able to easily add this capability.

Bill Rose, chair of CEA’s R7.8 working group that developed the standard said, “With CEA-2047/CE-EUI, energy consumption in the Internet of Things can be broken down to individual devices such as appliances, pool pumps and heaters, air conditioning systems, and other devices so consumers can see exactly where, how much, and when electricity is being used. The standard will also enable consumer-authorized, third-party developers and services to grow by providing them the information they need to help consumers save on their energy bills.”

Publication of CEA-2047 parallels other initiatives within the industry to reduce and monitor energy consumption. Other CEA standards in this area include CEA-2037-A, Determination of Television Set Power Consumption and ANSI/CEA-2043, Set-top Box (STB) Power Measurement.

CEA cooperated with the Smart Grid Interoperability Panel (SGIP) on the development of CEA-2047. The standard will now be submitted to ANSI to become an American National Standard.

In the 21st century, security on the Internet has become one of the most important issues. We hear more and more about cyber-attacks on the websites of large corporations, banks and even small businesses. When online we’re concerned not only for our own safety but also our privacy. We have to know that hackers usually start their preparation by investigating the private information of admins – the habits, interests, visited websites and so on. On the other hand, our own security is in danger bec...
Enterprises have been using both Big Data and virtualization for years. Until recently, however, most enterprises have not combined the two. Big Data's demands for higher levels of performance, the ability to control quality-of-service (QoS), and the ability to adhere to SLAs have kept it on bare metal, apart from the modern data center cloud. With recent technology innovations, we've seen the advantages of bare metal erode to such a degree that the enhanced flexibility and reduced costs that cl...
Fact: storage performance problems have only gotten more complicated, as applications not only have become largely virtualized, but also have moved to cloud-based infrastructures. Storage performance in virtualized environments isn’t just about IOPS anymore. Instead, you need to guarantee performance for individual VMs, helping applications maintain performance as the number of VMs continues to go up in real time. In his session at Cloud Expo, Dhiraj Sehgal, Product and Marketing at Tintri, wil...
As software becomes more and more complex, we, as software developers, have been splitting up our code into smaller and smaller components. This is also true for the environment in which we run our code: going from bare metal, to VMs to the modern-day Cloud Native world of containers, schedulers and microservices. While we have figured out how to run containerized applications in the cloud using schedulers, we've yet to come up with a good solution to bridge the gap between getting your conta...

DevOps theory promotes a culture of continuous improvement built on collaboration, empowerment, systems thinking, and feedback loops. But how do you collaborate effectively across the traditional silos? How can you make decisions without system-wide visibility? How can you see the whole system when it is spread across teams and locations? How do you close feedback loops across teams and activities delivering complex multi-tier, cloud, container, serverless, and/or API-based services?
Today every business relies on software to drive the innovation necessary for a competitive edge in the Application Economy. This is why collaboration between development and operations, or DevOps, has become IT’s number one priority. Whether you are in Dev or Ops, understanding how to implement a DevOps strategy can deliver faster development cycles, improved software quality, reduced deployment times and overall better experiences for your customers.
The Internet of Things (IoT), in all its myriad manifestations, has great potential. Much of that potential comes from the evolving data management and analytic (DMA) technologies and processes that allow us to gain insight from all of the IoT data that can be generated and gathered. This potential may never be met as those data sets are tied to specific industry verticals and single markets, with no clear way to use IoT data and sensor analytics to fulfill the hype being given the IoT today.
