Jaclaz, yes, you are right, there are quite a few companies in this field. Every company has its own approach. For example, Curb does not make device detection, but shows you statistics on the circuit level (you need to connect it to every circuit breaker), Neurio detects only devices which consume more than 400W, etc.

In our case, we are focusing on reliable device detection of major home appliances (we detect home appliances which consume more than 100W). We detect devices by our algorithms and users can teach the system via training mode for more precise recognition. Beside this, we support 3-phase electrical networks (for both grid and grid+solar) and we support 220V/50Hz networks (so Ecoisme works in both Europe and US).

Maybe it would be useful to highlight somewhere, maybe a small factsheet as a .pdf, such differences/enhancements, from a quick look at your site I couldn't detect those.

And - at least to me - it would be interesting if (without of course revealing any trade secret) you could describe how you can identify devices, i.e. which parameters allow you to distinguish (or classify) devices connected to the same breaker.

Something like this (now old) paper? http://abstract.cs.washington.edu/~shwetak/papers/ubicomp200...
