The Current Cost Individual Appliance Monitor (IAM) allows you to monitor the power usage of either a single appliance or a set of appliances plugged into a multiway adapter.
The IAM teams up with a Current Cost EnviR and is added the same way as the additional transmitter. The readings can be seen on the main display of the Current Cost EnviR.
