EG41xx and EG3010 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.
- 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 but may be found used or as old stock from other sources.
