Trying to get a better grip on power usage both for our own household and the MIL, who lives in the flat next door.  In particular, she is running up massive power bills for someone living alone and I can't make sense of it.  Every time I look at the meter, usage seems normal for whatever is switched on at the time.  And I tried various isolation tests, also seemingly normal.  Seems like something is happening when I'm not watching ;)

As getting her to change providers (Contact - who only give monthly readings and nothing else) is going to be a hassle, and it seems like none of them give you good granular data in a timely manner anyway, I opted for a SmartNow gateway and two Senseable transmitters (one for our meter as well because why not).

These should provide readings every 5-6 seconds for both households.  I figure the initial outlay (close to $300) should pay for itself in power savings as problem usage is identified and resolved.

I've got them both working and giving readings but having trouble getting the gateway registered on the website, my.currentcost.com - I've let them know about it and I'll let you know how I get on.
