Athom Homey Pro

Installed in an electricity box, the energy meter will monitor the total consumption of electricity, used by an entire building. And its intelligent clamps will report, that energy use back to your Z-Wave gateway or controller in real time. So you can see, how much electricity you really use and when you use it.

Fantastic wireless range
It wires into your electricity box for improved performance, and it also offers great wireless communication. In fact, when perfectly positioned, the home energy meters will be able to communicate your home's electricity use to Z-Wave devices.
   
Improved accuracy
Now you'll have access to all the data you need, whether that's the amount of watts your home is using or the amount of kilowatt-hours you should be charged for, and all in real-time.
