When working on large sites it is common to split the Z-Wave mesh over several gateways, for example creating separate networks upstairs and downstairs. This has the advantage of splitting communication and improving reliability but the downside of splitting devices across multiple separate My Nero connections.
This can be resolved by selecting a primary gateway and linking all the other gateways to it, allowing the Z-Wave networks to operate independently but showing the user a single unified interface on a single connection.
UPnP scanning time
It can take quite a while for the chosen primary gateway to perform a full UPnP scan of your network. This scan can be started at any time before you plan to link the gateways together, allowing you a quicker linking process when the gateways are ready.
To start the scan ensure all of your gateways are connected to the network and fully powered up. Then follow steps 1 through 5 of the linking process below. Once you have reached this point you can continue building your Nero network or perform other tasks before coming back to this wizard to complete the linking.
Linking the gateways
Before linking gateways together ensure that all of the devices are working correctly. Troubleshoot any errors or issues before linking gateways together for a smoother linking experience.
Make life easier, ensure that you name all devices, including child sensors of the NERO-MULTI, sensibly before linking the gateways together.
- Select a gateway to use as the master. For optimal performance, we recommend selecting the gateway where the most scenes/automations will have direct Z-Wave communication paths but any gateway can be selected.
- Log in to the web interface and go to Devices then select Add New Device.
- Select UPnP devices.
- Select the checkbox to Scan for UPnP devices and then click Next.
- Wait for around 15 minutes if the checkbox was not already activated. You can exit the wizard while you wait and complete other tasks.
- Select the gateway from the list you want to pair to this primary gateway. The serial number will help you identify the gateways found.
- Repeat for each secondary gateway you need to link.
Cleaning up the interface
After a few minutes, the devices on the secondary gateway will be replicated on the primary gateway. You can not assign them to rooms so that the interface is easier to use.
Be patient. When re-homing many devices the engine can sometimes slow down as it processes all the steps involved in moving a device. If you feel the UI is reflecting the wrong information try refreshing the page.
On some networks, UPnP scanning may not show the other gateways. There are a few steps you can try to resolve this.
- Temporarily disable the firewall on all gateways then search again.
- Go to Settings then Net & Wifi and select Manually configure (advanced) in the network section.
- Set the firewall to disabled.
- Click save and apply.
- Try a search for the primary gateway from the secondary gateway. If it is visible then try again from the primary.
- Plug both gateways into the same physical switch. If you only have a modem/router with built-in switch plug both gateways into these switch ports.
If you are still unable to locate the gateways from the wizard, get in touch and we can perform a manual linking for you. Submit a request to email@example.com with the following information included:
- Support codes for all gateways (Settings then Customer Care then click Enable at the bottom of the page. Copy and paste the code that generates, please do not send screenshots).
- Note which gateway should be the primary unit.
We will inform you once the pairing is completed.
