GreenWave Reality launched its Z-Wave based home automation system with energy, water and gas consumption meter. It includes a GreenWave Reality Gateway, Energy Display and PowerNodes (intelligent power strips). Any other Z-Wave devices produced by different manufactures can be used as well (viva Z-Wave!). The Gateway communicates with Z-Wave devices, control them and collect energy/water/gas consumption data. The Energy Monitor grubs that information and shows it to consumer in clear way. It also can be used separately in any Z-Wave compatible system.
The Gateway can be connected to Internet. In that case the system can be managed remotely as well as update its firmware. There is no any info about price and availability yet. But GreenWave Reality system looks very promised.
