I have just come across this, having been thinking for a long time about how to best monitor my energy, and this could be cost effective vs buying zwave devices for sockets and relays etc to monitor more applicances.
I am guessing from the fact this has been written, and that I dont see major complaints of the device even from @durosity, that it works well. Do people use it to monitor appliances, or just overall energy.
I also am interested in the gas as well. Would I see spikes in use etc when the boiler kicks in, is it that real time? That would be awesome.
