Product Description
The Rate$aver is an In-Home-Display (IHD) device capable of communicating with Smart
Energy Profile compliant Energy Service Portals (ESP) within electric meters to display
current energy consumption, utility rates, billing history, messages, alarms, temperature
and time. The device consists of display technology requiring no power consumption to
display graphical images enabling true, wireless battery operation. The device operates
on 2 AA batteries and incorporates a 100 mW high performance Zigbee radio.
