Home Assistant Connect AUX-2 takes power from either a Power over Ethernet (PoE) switch or injector, or a USB-C supply. Use one source at a time. Wired Ethernet works with either power source.
| Power source | Wired Ethernet | Wi-Fi |
|---|---|---|
| PoE | Yes, power and network over the same cable | Off |
| USB-C | Yes | Yes, when no Ethernet cable is connected |
Wired and Wi-Fi together
Wi-Fi is off while Connect AUX-2 has a wired connection, over PoE or Ethernet.
On USB-C power, if you unplug the Ethernet cable, Connect AUX-2 falls back to Wi-Fi, as long as Wi-Fi was set up on it before. On PoE, unplugging the cable also cuts power.
Turning Wi-Fi off doesn't affect Bluetooth.
Recommendations
- PoE: one cable for power and network. Recommended where PoE is available.
- Wired (PoE or Ethernet): recommended when using a Connect radio adapter, or when you want the most reliable link.
For electrical figures and the Wi-Fi standard, see Specifications.
