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.
