Troubleshooting instructions for:
Version: 2019-07-23

General description:
The CAVIUS Gateway is designed as the “Hub” for the CAVIUS alarms on one frequency and to home automation devices such as door sensors and motion sensors on another frequency.

The Hub is connected to the router in the home with the ethernet cable.

The Hub will act as any other alarm in the system. 

From the app it is possible to send out a test signal just like the alarms can by pushing the test button for 3 sweeps. 

When the Hub receives an alarm or signal, the notification will be forwarded to the smartphone through the App and/or to an email.

The alarms from the wireless family are not depending on the Hub to be powered on or have internet connection. If the internet is down or the power disconnected, the alarms will still send alarm signals to each other and go into alarm if the signal is sent out, but the home automation sensors, like door and motion sensors, will not function until the hub is powered up and the internet is on again.

The CAVIUS HUB troubleshooting guideline:

For interconnecting the alarms please follow the direction given in the App and if you already have serial linked Cavius alarms please proceed directly to STEP 10: interconnecting alarms via the Cavius HUB

STEP 1: Update your router 

Check if the router has been updated (Firmware) and/or restart your router before connecting the Cavius HUB for the first time. To update the router, open the browser and key in

If the router has been provided by the internet provider – contact the provider and have them remotely update your router. 

STEP 2: Connecting the HUB to the router

The HUB needs to be connected to LAN gate and not the WAN gate or TV gate. If you are unsure about which gate is the LAN, you can connect your PC network cable and check if you are online on your PC. 

STEP 3: LED light

If the: 

  • RED LED light is flickering, the HUB is trying to access the internet
  • RED LED light is on, the HUB cannot access the internet and you should proceed with STEP 2
  • GREEN LED light is on, the HUB is connected to the internet

If the LED light is off, the HUB needs power. If the LED light does not turn on after being plugged in, please check your USB power source with another device. 

If the HUB does not work according to the manual and after you have gone through the trouble shooting guide, please contact the place of sales for further assistance. 

STEP 4: Internet connection

If the Hub is not able to connect to the Internet try to restart your home router or take out the RJ45 data cable also try to check with your local Internet provider for any fallouts in your area.

If the restart has not worked, please disconnect the HUB from the router and wait 12 hours before reconnecting the RJ45 data cable to the router. 

STEP 5: Does it work at your neighbour?

Before proceeding with more complicated steps, try connecting the hub to a router at another location. If the hub works elsewhere, then please proceed to step 4. 

STEP 6: Checking the router ports

If the Internet is working, you should check the router ports. A home router typically has 1-4 LAN ports. The hub should be connected to one of those. If you use a WAN port, then it will not work, and if your home router has ports reserved for TV or service then they will not work either. You may have to check the router manual, or simply try another port. Some routers require you to login to your home router to enable more ports. 

To test a port, connect your PC to the same port on your home router as the hub was plugged into and check for Internet connection.

STEP 7: Do you have to restart or update your Internet equipment?

Home routers are built as specialized computers with memory, software and therefore have data to process. The hub will continually try to communicate with router and is therefore often the first messenger with problems in your network. The router may work for some Wi-Fi connections, but not for others, due to network overload.

Having installed your own router behind equipment delivered by your Internet supplier to get more LAN ports is not a problem but will add to items to reboot and update. 

STEP 8: Company controlled network

Company networks are often controlled by an IT-department and will sometimes make use of advanced home router settings. If you have received your router through your company’s IT-department, please contact them to check if such advanced router settings are in place. 

Step 9: Advanced settings or router update

If none of the above steps works you either must proceed to advanced settings in your router or consider acquiring a new updated standard router. 

That said, in rare cases you will have proceed to advanced settings in your network equipment. 

  • Is DHCP enabled?

DHCP enabling guides are widely available online. 

  • Are some MAC addresses blocked or filtered?
  • Is UDP traffic enabled?
  • Is UDP connection timeout above 40-60 seconds to avoid frequent fallouts?

STEP 10: interconnecting alarms via the HUB

If you already have interconnected alarms, you need to disconnect them in order to re-connected via the HUB. 

Take the alarms – one by one – and put them into “learn mode” by switching the black slider-button on the back of the alarm. The LED must have a continuous light. Press the test button until you hear a short beep, release the test button and let the alarm beep for a few second before switching the black slider-button in to “normal mode”. Repeat with all connected alarms. When all alarms have been disconnected from each other please proceed with connecting them via the HUB by following the manual and instructions from the app. 

After following the above guideline and the HUB still does not work please note down or take a picture of the PIN and ID on the back and contact the place of purchase.
