I went for the Efergy Hub Kit http://efergy.com/nz/products/energy-gateways/engage-hub-kit#.WQK7bMYlFaQ but paid a bit extra and swapped the transmitter for the DIN rail mounted one (cant find the link to that now). Makes the switchboard a bit neater.

I just hope whatever components they use in it are better than the ego they make. My 2 are both dead now, signs are dead caps - power light just dimly flashes. It used to come on eventually if I left it but now just flash away for weeks if left plugged in. Cant open them because they use a stupid screw to close it and I dont have a triangle bit that fits.

I had to search through my emails to find the order, but I purchased mine May 2013 and it has been fine.

neb: A lot of those use current clamps, which aren't nearly as precise as pulse-counting meters. Also if you've got a DIN-rail power board the meters are a lot less intrusive to install.

On our loads I find the current clamps to be pretty accurate. There might be a 10-20kwh difference to my actual bill over a month (550-600kw/h per month). Since I don't know the exact time of day the meter was read, there could be half a day on each read that I haven't included, which explains most of the difference.

less than 3.5% is pretty accurate

The Efergy unit is the only one with a display unit that I can wall mount for the whole family to see. If I'm the only one with the app on my phone or access to the web dashboard, then I can't drive behaviour change to decrease our usage. For me, that display unit is an important part of the equation to get something like this.

Does the display unit still log the data to the website? I find the most useful thing is looking at historical data rather than instantaneous. After a while you can look a the day's usage and see when you boiled the jug or turned the oven on, so you know when something different happened.

Their Elite hub unit & RCS @ $209 seems to do both.
