What do the different LEDs on the HomePlug adapter mean?

EG4xxx and EG30xx meters can function with a wide variety of HomePlug AV compliant powerline communication adapters. Some officially supported adapters and their LED keys are shown below.

NOTE: Other HomePlug adapters from different manufacturers may work. However, since they have not been tested by eGauge we cannot guarantee full functionality. Troubleshooting and support may be limited in these situations. HomePlug 1.0 adapters are no longer available directly through eGauge - please see our article on locating replacement HomePlug 1.0 adapters for more information.
