[RE-wrenches] Smappee anyone?

Hi:

Haven't seen such before and don't have any experience with it, but 
personally I see this as a very cost effective and powerful approach to 
load/energy monitoring.

With just the one set of sensors, (two if you have solar), you can gather 
a detailed load use and solar harvest profile.

Regarding identifying load signatures, from what I can gather you wont 
need to tinker with it to get the data.  It will recognize and log the 
load data, it just wont know what the various loads are called so they'll 
be labeled as LOAD1, LOAD2,....etc.

Looking to the future, I'd be surprised if you don't get firmware updates 
as their software engineers get better and better at load recognition.

I like this one.

Happy Holidays,

http://blog.stefangrosjean.net/2014/08/30/find-my-appliances/

Here is a link to the inventor’s website which explains the theory behind 
the “Smappee” energy monitor; i.e. that each load has its own unique 
electrical use signature “DNA” and that (over time) Smappee can identify 
such signatures and track them. This without the need for plug-in modules 
or individual current transformers on each load, which we have done in the 
past.

This originated in Europe, I believe the Netherlands, and was launched in 
the US 12/10/14. They have both a droid and iphone app, I found no reviews 
for the iphone.
Interesting in concept, but if you read the inventor’s blog it sounds like 
it will take time for the monitor to actually sort out multiple load 
signatures. And then the homeowner has to label them as furnace, fridge, 
etc., for the monitor only knows a particular signature is unique, it 
can’t identify an appliance on its own. So it sounds to me a lot of 
potential tinkering would be required for it to ultimately be useful. 
Definitely not a plug-and-play item. Anyone perchance have experience with 
this? Thanks.
