6.2. VLAN and Network Interface Configuration

(available only on Domotz Hardware)

These details are meant for users who have multiple VLANs or want to configure the Domotz Hardware on a Static IP and are already aware of related configuration and procedures. For further details and step-by-step guides on how to configure VLANs on switches and Domotz Agents, the user should refer to detailed guides (for example, please refer to:

In order to allow Domotz to discover and monitor devices on two or more VLANs, the user should configure both the switch and the Domotz Agent for multiple VLANs:

6.2.1. Switch Configuration

The interface port of the switch which will be used to connect the Domotz Box/Pi, should be configured:


  • in Access mode / Untagged for the main interface used by the Domotz Box/Pi to communicate with the gateway (e.g. eth0).
  • in Trunk 802.1q mode / Tagged for the additional VLANs to be monitored (e.g. the eth0.10 used for lan 10)
  • Please refer to your specific switch/model guide on how to configure Trunk 802.1q and Access mode (Untagged/Tagged) for the port.

6.2.2. Domotz Agent Configuration

You can find all the necessary information for configuring the Domotz Box to monitor multiple VLANs or to configure the Domotz Box with a Static IP in the Network Info section of the http portal.


Network Info:

When you press the Edit button you will see:

Switching the DHCP toggle to Off you will be allowed to specify Static IP and non-DHCP based subnet mask, Gateway and DNS servers.


When pressing the VLAN Config button you will see the following screen which will assist you in this configuration.

For every VLAN that you want to add, you need to specify:


  • the Identification number of the additional VLAN
  • the Static IP address of the Nework Inteface of the Domotz Box on the additional VLAN
  • the subnet mask on the additional VLAN

Make sure that the IP Address on the additional VLAN is not in use, and it is not the *.*.*.0 of that subnet (e.g. do NOT use IP addresses like

Devices discovered on the tagged VLANs cannot be blocked/paused through Violet - Customer Facing App (Violet Digital Support Client App) due to technical limitation to the implementation of the pausing functionality. Domotz recommends configuring the Domotz Box on the same subnet as primary interface where devices which might be blocked through Violet Digital Support Client App are expected to be.
