HomePlug AV Adapter

Current manufacturer information: TRENDnet model TPL-406E

The HomePlug AV adapter is used by compatible eGauge models to bring network communication over the existing building power lines. The HomePlug AV adapter plugs directly into a 120V outlet, connects to the router/switch using Ethernet, and compatible eGauge models can communicate over the power-line for network communication.

HomePlug communication is only recommended for residential uses, and is not needed when using an alternative communication method, such as Ethernet direct, cellular, or WiFi.

Hardware included:

1x HomePlug AV adapter

1x 5-foot Ethernet cable


  • Do not push or hold the button on the HomePlug adapter without full knowledge of pair/reset process. Pushing the button on the HomePlug adapter may result in communication loss.
  • Do not plug HomePlug adapter into surge protector or UPS.
  • Ensure HomePlug adapter is powered by same phase as eGauge meter L1 connection and is not more than 100 feet of wiring distance from the eGauge meter.

Assembly/installation information

Connect the HomePlug adapter to an outlet powered by the same phase as the eGauge L1 near the network router/switch. Connect the Ethernet from the HomePlug adapter to the network router/switch. All HomePlug devices and eGauge meters come with the same default encryption key of "HomePlugAV", and should link up if they have not been modified or paired with the push button pairing process.

Software configuration Information

The HomePlug adapter and eGauge can be paired with a unique encryption key. See this article for more information.
