Sometimes, even with a working router and correctly connected LAN cable, the UGE600 gateway fails to go ONLINE (blue LED missing). Below are possible reasons and a fallback configuration in Offline (Local) mode.
1. Basic checks
- Power on – green LED = OK.
- LAN cable plugged into router.
- Try a different LAN port or cable.
- Blue LED = ONLINE – if missing, continue troubleshooting.
2. Possible reasons
- Router blocks outgoing traffic (ports, MAC filter).
- Gateway requires firmware update (OTA).
- IP address conflict in LAN.
- LAN port fault (rare).
- The phone/tablet running the app is on a different network, or a VPN is enabled – the gateway and the app device must be on the same router Wi-Fi/LAN. If they are not (or a VPN is active), the app will hang when searching for the gateway via LAN.
3. Temporary fix – Offline mode
If Internet is not available, use Offline mode:
- Power the gateway (green LED).
- Press and hold button for 5 sec → flashing red LED = ZigBee open.
- Pair devices (KL08RF, TRV, RX10RF).
- Press button again (5 sec) → solid red LED = ZigBee closed.
- Gateway now works in local mode.
When Internet is restored, scan gateway in SALUS Premium Lite app – the system will automatically switch to ONLINE mode
4. Firmware update (for new devices)
If UGE600 never connected to Internet before, it may need OTA update:
- Connect via LAN to router.
- In SALUS Premium Lite app: “Local WiFi Mode” → “Scan My Home” → start OTA update.
- LED sequence: red → green → blue = update complete.
Checklist
✔ Green LED on
✔ LAN cable checked, router active
✔ Other devices online
✔ Blue LED off
✔ Use Offline mode (red LED)
✔ After OTA/Internet – switch to ONLINE
✔ App device on same Wi-Fi as gateway; VPN disabled
