This article applies to all TeamViewer Embedded users and requires TeamViewer Embedded Agent 2..11 or higher.


OPC Technology stands for “Open Platform Communications” and is an approved communication standard for the process industry. The OPC Unified Architecture (UA) is an interoperability standard and provides a secure and reliable data exchange mechanism.

OPC UA is a platform-independent system and ensures information flow between devices from multiple vendors.

For real-time data access, the OPC Data Access specification is being used.


TeamViewer Embedded provides an OPC UA Connector that connects to the OPC UA Server and collects values from OPC UA Variables. The connector finally communicates with TeamViewer Embedded Cloud with the help of Embedded Agent.


Connect with the TeamViewer Client to the device and use Remote Terminal

Run this command:

sudo teamviewer-iot-agent install opcua

Connector Configuration

In most cases, the OPC UA servers are being configured by other companies. And the configuration is specific to the installation and the environment where it is being used.

You need to configure the OPC UA Connector according to your server's configuration by providing the URL of the server, security settings, and authentication options.

To do this, you need to edit the opcua.conf file. The file is located in /var/lib/teamviewer-iot-agent/scripts/opcua/ directory of the Edge Device.

Below are the parameters included in the file:

# Server Information

# Security Policy
# 0 - None
# 1 - Basic128Rsa15
# 2 - Basic256
# 3 - Basic256Sha256
# 4 - Aes128Sha256RsaOaep
# 5 - Aes256Sha256RsaPss

# Message Security Mode
# 0 - None
# 1 - Sign
# 2 - Sign & Encrypt

# Authentication Settings
# 0 - Anonymous
# 1 - Username & Password
# 2 - Certificate & Private Key

# If "Username & Password" is selected

Adding a Sensor via OPC UA Connector

Login in TeamViewer Embedded Management Console From navigation panel click on Inventory. Select the Edge Device where the Connector is installed and from dropdown menu on the right select Add Sensor

Choose the OPC UA from the Connectors section.

Provide the Node IDs as they are specified in the server. Associate the OPC UA Nodes with a metric name that will be displayed in Teamviewer Embedded Cloud. All the metrics are grouped in a sensor instance. Finally provide the scan rate at which the data will be requested from the server and save your configuration.

Monitor the values received from the OPC UA Server by pining the configured metrics to the Dashboard.
