Next Gen Whole House Energy Monitor

EMonitorinstalled

Most of the energy monitoring tools on the market right now gather aggregate information about the overall electricity use of a home.  But the new eMonitor from PowerHouse Dynamics could change all this with circuit level monitoring.  The eMonitor solution combines hardware, software, and service elements to provide home electricity use, electricity cost, and carbon footprint information by the minute.  Past and present information is then available online and on the iPhone (starting in about Q2 2010).

Information gathered by the eMonitor is detailed and thorough and, in the hands of the right homeowner and home, could help save 5-20% or more on energy bills. 

The single-unit solution monitors 24 circuits, or 2 main and 22 additional circuits, in either the 120V or 240V variety.  eMonitor can also be integrated with solar PV, solar thermal, or wind installations. 

eMonitor has a ZigBee antenna to control various add-on devices, such as smart outlets, smart thermostats, etc, but these capabilities may not be available until Q3 2010, or thereafter. 

According to a press release, Energy Circle is selling the system online.  Purchasers should have the eMonitor installed by an electrician, but there's a video on Energy Circle's product page explaining how that works.  The single-unit system is available for pre-order for $799.00 and includes five-years of bundled monitoring service.

    Really interesting to see energy monitoring on circuit level in residential start having product development, thanks for sharing!

      EcoDog manufactures this already. They measure to the circuit level on ALL circuits, no matter whether you have sub panels, solar, wind, anything. http://www.ecodoginc.com
      EcoDog is currently selling into the market as well. They also net solar use versus generation, using REAL billing data, so you are able to see your bill in real time

    i am so glad to see manufacturers start getting into the residential energy monitoring market. i’ve been waiting for this kind of thing for a long time. all too often, we just keep paying the electric bill because it’s always been about the same, but that about the same doesn’t necessarily make it energy efficient. imagine if we could install these on all the home in the US and homeowners would be required to cut there energy usage by just 10% (easy to do if they monitor it). great post!

    Hey that looks like a great product. It’s a little pricey, but has so much more functionality than those which only monitor total household usage. With this level of granularity it becomes much more likely to engage occupants in energy saving measures. I’ll be offering it as an accessory for the green backyard cottages my company sells in Seattle – Backyard Box http://www.backyardbox.net

      Wow, your Backyard Boxes will be pretty slick. Can’t wait to see a few of these as they roll out.

    799? I can get an Envi from forward energy solutions for 129, doesn’t take much to buy extra current clamps to break up the circuits…and I am sure it would cost a lot less then 799. Check it out… http://www.forwardenergysolutions.com/energy-monitor.htm

    I was interested in this… until I spied the monthly fee :(

    I hate monthly fees even more than phantom power!

    Someone mentioned this solution on another site and it looks very promising:

    You can cascade units together to cover what you need – that means you can also incrementally expand so you don’t have to eat $800 all at once! And they offer support for pulse meters for water and natural gas. It looks like the natural gas meters have to be plumbed in – ack! I have no problem plumbing in a water meeter, but I dunno if it would be worth it to pull a permit and get a natural gas meeter installed – although it would be nice to know the split between my gas fireplace, furnace and water heater in the winter.

    I would like to monitor individual circuits to know exactly where the money is going. But I find the annual service fees for the eMonitor a big turnoff (not to mention the hefty initial cost).
