Avia device LED status guide
What stable, blinking, or missing indicator lights mean, and what to do for each.
The Avia device uses indicator lights to confirm whether it is powered on and connected correctly. During installation or troubleshooting, checking the lights helps identify whether the device is ready, still connecting, or needs further support.
The three indicator lights
The device has three lights:
P — Power: the device is receiving power.
S — Connection: the device has a network/internet connection.
L — Transmission: data is being transmitted over Ethernet or PoE.
Normal case
Wired (Ethernet or PoE): P and S should be stable, and L can be blinking — this means data is being transmitted. This is the normal, healthy state.
Wi-Fi: only P and S should be stable. L does not light up or blink on Wi-Fi connections.
What to check
After connecting the Avia device to power and internet, check the indicator lights. In a normal setup, P and S become stable after the device finishes starting up. If P or S are blinking, off, or not becoming stable, the device may still be connecting or may need troubleshooting.
Stable lights
When P and S are stable, the device is powered and connected correctly. Continue with device registration or the next setup step.
Blinking lights
If P or S keep blinking, the device may be still starting up, connecting to the network, or unable to complete the connection. (On wired setups, a blinking L is normal and means data is being transmitted.) If P or S continue blinking for more than a few minutes, check:
The device is connected to power
The Ethernet cable is properly connected, if using Ethernet or PoE
The PoE switch or injector is powered, if using PoE
The Wi-Fi network is available, if using Wi-Fi
The device and phone are on the same network during setup, if using the mobile app
No lights
If no lights appear, check the power source.
If using a DC adapter:
Confirm the power adapter is plugged in
Try another power outlet if available
If using PoE:
Confirm the switch supports PoE
Make sure the cable is connected to a PoE-enabled port
If using a PoE injector, confirm the injector is plugged into power
