List of Energy monitoring tools : devices, software and home automation


Home Energy Monitors

Home Energy Monitors

With all the buzz from the announcement Google made regarding their partnership with Energy, Inc. and the TED 5000 I decided now would be a good time to provide a summary of all the companies in the residential energy monitoring space.  This list was compiled with the help of articles I read posted on Earth2Tech and Open4Energy.  I'm not doing an in-depth review of each company, just a link to their site and a few thoughts.  This list is a work in progress so please let me know if I am missing products or if you have experience using any of them.

***Update 10/8/09 - I've updated the list with companies focused mainly on solar PV monitoring as well.

***Update 10/28/09 - Two companies on this list have teamed with Google and their PowerMeter software.  See my posts here: TED 5000 and iGoogle and AlertMe.

***Update 12/31/09 - If you are new to Energy Monitoring see our post on Energy Tools for Newbies - Real-time Energy Monitors!

  • Wattson - Device. Stylish. UK and Australia
  • Wattvison - Soon to be released.  Looks like a combination of TED 5000 and PowerCost monitor i.e. a web enabled meter reader.  Has the potential to be more popular than TED 5000 because you dont have to install it in an electrical panel.

I was surprised to see how far along the UK was in this area.  I will say that companies that dont have a web based component (i.e. log on to your computer or iPhone to see energy consumption) probably wont last long unless they are cheap.  I believe energy monitoring is most effective if it is done with history tracking, which is best achieved with web monitoring.

What other companies are out there?  How many of you have tried the devices on this list?

Simon, What about something like the option from <a href="" rel="nofollow">Computerized Electricity Systems</a>? Instead of having to install many different meters at each outlet, you can just install one master breaker pane. The only thing is that I dont know if it is rated to work in the U.K.?

They may, but I'm trying to focus solely on residential. It is a much different space than commercial/industrial.
Check out MillennialNet ( They have a wireless mesh sensor network for tracking energy usage in large commercial facilities and schools. They started out of MIT as a mesh network innovator and are gaining traction by providing the energy monitoring solution
I am very happy with TED 5000. I immediately learned my clothes dryer was cycling 30amps to start its motor every 5 minutes all night for wrinkle free tumble. Toggled that off, better to remove the clothes. I began replacing my outdoor landscape lighting (35 lamps 10-20 watts each) with energy efficient LEDs. TED says I saved 10-15% of my monthly bill after the initial LED bulb purchase. TED profiling doesn't seem to work very well for me. Thinking of adding more MTUs to monitor big appliances separately, A/C, Furnace fan etc.
Does anyone have any information on how large the residential energy monitor market is, as in not only the players involved, but current customer base/potential customer base, revenue, forecasting, etc.?
Spenc, Let me know if you find that data. I would love to look at it. I think you could look at the U.K. as a good model for it. Currently the market in the U.S. is still probably small, but as energy prices rise and people become more "energy conscious" there will be a greater demand.
Another product for your list - <a href="" rel="nofollow">Gridspy</a> " Gridspy provides you with an interactive view of resource usage in your building. The Gridspy allows you to access and monitor your consumption patterns in real-time using a standard web browser on your PC, laptop or mobile phone. The data is presented in high resolution and updated each second as you watch.

" We have a <a href="" rel="nofollow">development blog</a> and a <a href="" rel="nofollow">live demo</a>. Our devices monitor several circuits from your switchboard and upload data each second for immediate consumption in the web-based interface. We are currently deploying prototypes and slowly scaling up our hardware production. Accepting orders in New Zealand with plans to enter wider deployment early next year.
Pulse Energy has a SaaS commercial building energy monitoring product.
This is great blog! If you want to see the ultimate product for real time monitoring of energy consumption by circuit combined with managing alternative energy source checkout this link for the product video: The product sells at a starting pprice of $575 (can monitor up to 48 circuts)and can be field upgraded to the highest end product with alternative energy monitoring and utilization. Feel free to contact me with any questions. Shlomo,
Shlomo, I'm very intrigued by the C-E-systems product. How long has it been for sale in the U.S.?
