Wattvision tends to cut your power use, because you're probably wasting power in ways you don't know about. When you first install it, your initial reaction is generally "why are we using so much power?" Then you walk around turning things on and off and watching what happens to the graph. You usually discover some surprises in the process, and those change your behavior.
You make what you measure. Watch any number carefully enough and you'll tend to optimize it, and most households have significant room to.
- mikeryan 17y agoI can understand the first usage being kind of interesting and enlightening, but I'm not sure if its $200 kind of interesting. It seems like this would be of more interest for commercial applications.
- netcan 17y agoI've always thought that light switches & sockets should have meters on them.

- gridspy 17y agoUntil recently it was very difficult to get the data from the sensors to a useful place. Wireless networks and common always on internet connections have changed that.
- netcan 17y agoWhat are the chances some sort of clever metering will be built in to new, higher end houses?
- gridspy 17y agoExtremely likely. There are good chances that in 30 years most houses are as automated as our off-grid house on Great Barrier Island and come with power monitoring as standard. http://blog.gridspy.co.nz/2009/08/the-barrier-house.html http://blog.gridspy.co.nz/2009/08/the-barrier-house.html We plan to provide the devices today.
- savrajsingh 17y agoYes, extremely likely. Hey gridspy guys, do you want to see if we can find some common ground between wv and gridspy? :) ping info@wattvision.com
- brk 17y agoI wouldn't bet on it too soon. When I was involved in the home automation industry back in the mid/late 90's it seemed like that sort of thing was imminent. Invensys and CutlerHammer both had power-monitoring devices, electric meters and so on (I still have some CH power monitoring sensors on the main power lines at my house with a system that I put together that tracks KwH, heating oil consumption and a few other metrics). Anyway... I haven't really seen those products move an inch in the last dozen years (other than press releases). While I do believe that the real-time feedback is helpful, I also more strongly believe that people who really want to cut their power usage will do so by simply turning more things off or using things less. For the most part, a monthly feedback cycle isn't really THAT long. In some cases the month-long feedback loop let's you measure a more cumulative effect in dollars instead of cents.
- gridspy 17y agoInstalled cost for these home automation solutions quickly tends to exceed $1000 making them impractical as a cost saver. The sensor costs are suddenly dropping as competition heats up. Hopefully innovative, web enabled solutions from fast moving startups re-invigorate this sector. I'd sure love to.
- gcheong 17y agoWhat is the average time to recoup the cost of the meter and start actually saving money?
- gridspy 17y agoIf you believe the normal claim that you will save 10-30% and your average monthly power bill is > the cost of monitoring it will take you less than 1 year to pay itself off. So if your bill is $150 a month, this system (or similar) should pay for itself within a year - IF you try to save power using it.
- ivankirigin 17y agoSaving energy doesn't only have to be about money.
- alrex021 17y agoHow about a device that actually directly saves you power? Well that's what my friend's startup focuses on currently piloted in South Africa. The startup built a device that reliably saves power. You don't need to pay any fee up front for the device, you "pay as you go" on amount of saving made on monthly basis. No catch. Average savings currently are around 10-15%, engineering team is pushing the numbers up as we speak. Business has gotten necessary funding and even the primary energy supplier has come on board to put an initiative together that would implement the solution to all street lights in the country in the near future. South Africa is currently going through energy crisis due to huge demand and lack of supply. PS. My wife is one of the co-founders. :)
