If the OWL CM119 Wireless Energy Monitor is a bit expensive and feature rich for your requirements, then the new OWL Micro (CM130) could be the product for you.

OWL Micro

The OWL Micro is back-to-basics wireless energy monitor which only displays four values: current power usage, cost per hour at current power usage, total power used, and total cost of power used. Setting up the OWL Micro is very simple with just the average cost per kWh (unit) of electricity to be entered by the user (after checking their electricity bills).
