Wattvision (YC W09) Shows The Power Of Simple, Realtime Energy Monitoring

Honest question, is this solving a problem and who has this problem? I pay about $30/month for electricity and I already know it goes up to about $80/month during the winter months. $200 seems like a lot of money to pay for someone to tell me what I already know.

I'm one of the alpha users, and I've found it surprisingly interesting. When you install Wattvision, you can suddenly see all sorts of things you never knew about. For example, how much power electric kettles use. When I switch on our electric kettle, it doubles the power consumption of our house. Who knew? So now when I use it I only put in as much water as I need.

Let me save you $200:<p>- turn stuff off when it is not in use<p>- get rid of your old fridge/freezer<p>- get rid of any crts that you still have<p>- take a good look at wall warts and decide which ones really need to be plugged in when they're not charging something<p>- use a laptop, not a desktop, and enable powersaving<p>- use CFLS instead of bulbs<p>- run your heater at 18 degrees celsius (whatever that is in Fahrenheit)<p>- do <i>not</i> use electric heat for anything other than your quick-boil kettle, so no electric range etc.<p>There, that will save you $200 and at least that much in electricity.<p>The above list is a compilation of the outcome of a years worth of experimenting in a house that was powered by solar cells, the great insight of all that is that it is 10x as cheap to save a Watt hour than to generate one.

I saw a CNN story last week about Google's free energy monitoring software. Then at the end of the story was a huge let down: you need special hardware to get it running.<p>I checked Wattvision right after that and there were no updates, so today I'm super happy to see that the hardware is available. If it proves to work well, hopefully we'll see a story on CNN (i.e. to the public at large) in the next few months.

With the wealth of data that they collect, this would be a great place for an economist (like myself:)) to study usage patterns and possibly conduct experiments.<p>Of course, the set of people that buy this device are more "green" than the average consumer and also more likely to change habits. Nonetheless, looking at correlations of household-level usage with location specific variables like weather, sporting events,etc. could be really interesting. Moreover, conducting experiments where alerts are different for 50% of the users to test how responses differ would really illustrate how public policy should move forward. Think of the A/B testing web developers use, but with possibly wide-ranging consequences.<p>Great work!

I've been using a similar device for a year now - the Wattson Home Energy Meter (<a href="http://www.diykyoto.com" rel="nofollow">http://www.diykyoto.com</a>). It's not as full featured as Wattvision and doesn't connect over WiFi, but the information it reveals is extremely interesting and enlightening.<p>It's easy to merely understand power usage (I always have done), but to see it revealed and presented like this is particularly fascinating. It's makes you stop and think. This is a good thing, for both environmental and educational reasons.<p>I can't wait to get my hands on Wattvision, and good luck to them!

If you're interested in non-realtime energy monitoring (and speak German), check out my skunkworks project from way back: www.stromverbrauch-online.de<p>You sign up, regularly put in your current meter readout and get an estimate of your monthly and yearly electricity bill. No hardware required. I've gotten a number of signups since and some people really get religious about putting in their data - some do it every other day!<p>Getting your energy consumption down can be an interesting sport, see the Tweet-A-Watt.

People won't pay $200 to save a little money on their heating bill. People WILL pay $200 to have a facebook widget that says they were the #1 greenest home in their neighborhood/city. A little game theory applied to reducing energy consumption. Doesn't really have to be realtime either, if I could plot the energy usage of all my neighbors on a google map it would certainly shame people into submission.<p>Nobody really gives a damn about being green, green chic on the other hand... I can't wait to try it out.

This looks like a great product. Nobody seems to have mentioned the competitors, though, which include some pretty mainstream brands.<p>Black &#38; Decker EM100B Energy Saver Series Power Monitor: <a href="http://www.amazon.com/Black-Decker-EM100B-Energy-Monitor/dp/B001ELJKLE/" rel="nofollow">http://www.amazon.com/Black-Decker-EM100B-Energy-Monitor/dp/...</a><p>Blue Line PowerCost Monitor: <a href="http://www.amazon.com/PowerCost-Monitor-BLI-2800/dp/B0028LS5GA/" rel="nofollow">http://www.amazon.com/PowerCost-Monitor-BLI-2800/dp/B0028LS5...</a><p>I believe I saw the B&#38;D model on an episode of "Ask This Old House". Not sure if any competitors offer a web or iPhone interface, or just the receiver devices, but in any case this is a useful form of feedback that will likely become a standard feature as the monitoring equipment gets cheaper.

Very nice seamless implementation: device, connection, web-based, iphone. Full circle. Very professional. Great Name.

After my parents got a prius, they noticed that their gas mileage in their other car went up as well, because they learned how to drive more efficiently. What they really needed was feedback.<p>This looks like it could have the same benefit.<p>But the name...

No analog meter support. I'd have bought.

Very well executed. Hope it doesn't turn out to be an ice cream glove.

I couldn't find any info on how the thing reads the meter. Is it plugging into the meter via an open port, do these digital meters all have wireless transmitters themselves, or does it do something crazy like use a camera?

I live in a condo. Can I make use of the Wattvision?

Why do I have to click checkout to find out what the sensor price is? Even the pricing tab doesn't help...

I would buy this except $200 seems a bit steep.

Wow this is cool. I thought you were in the deadpool. Your pricing scheme is a bit confusing. It's very Microsoft-esq.
