I suspect that this sort of device could be removed by the power company should they discover it.The homeowner/tenant does not, in most cases, own the meter and some power companies could consider this a modification of the meter and have it removed. Heck, they might even bill you for the removal. I'm speculating, of course, but it seems like a real risk to me.

Either that, or the power company might start an investigation with law enforcement to determine if you have fitted the power meter with a device that misrepresents your electricity use.

I can only imagine the look on my meter reader's face if he saw a device like that attached to the meter.

One would hope that Wattvision launched(s) an education campaign aimed at the power companies to let them know of this device.

Earlier quoted context omitted.

Yes, it has. The sensor survived the harsh winter storm that dumped a couple feet of snow last winter in the Northeast.

What about other forms of harsh winter conditions - extremely low temperatures (including wind chill)?

Wind chill doesn't affect things that don't attempt to maintain a warmer temperature than the environment.

Wind chill is the effect of cool air passing by a warm object taking away it's heat energy more rapidly than stagnant cool air surrounding the object.

Wind does not cause an object to get colder than the air around it.

Ping confirmed that you are using google appengine.

>ping www.wattvision.com PING ghs.l.google.com (74.125.113.121) 56(84) bytes of data.

When you use federated login, google appengine is behaving as if request came from the same google assets. This is a major hole. However it is recommended you use following login method.

EDIT: Just reported the bug with appengine groups. http://groups.google.com/group/google-appengine-python/brows...

Sweet! We installed one at Anybots and it's surprisingly useful to know how much power the building is using. You make what you measure, or in this case use less of what you measure.

>>> UPDATE: Google confirms (see post by sean_lynch below): Google here, confirming this is an issue with the Users API on App Engine. On-call team is working on the fix now. >>> They rolled out a fix at 12:30PT. Ok will read up on that, thanks for confirming. We still cannot repro the exact issue, however.

Here are our repro steps:

- Inside an Incognito Window in Chrome, created a new Gmail account, signed out, signed in and checked "remember me". - In another tab, visited wattvision. Clicking my house brings up "wattvision uses google accounts for sign in" log-in window which asks for password.

Thanks for your help and support here!

I like it. Will you be shipping internationally? Just a note, the size comparison is not very useful since I:

1) Do not know how large that particular candy bar is. It could be a tiny one or it could be a huge one. 2) I have no idea how large that Reddit toy is.

:-)

Just use a different browser for the new account that you created. So many users reported the problem.

Incognito mode is not the one you should test with.

I think this is incorrect speculation. Black&Decker, for example, sells a similar looking device. I've had one on my meter for months and no one's said anything.
