Configuration

A device is a piece of equipment on the local network with an IP address or hostname that the Evolo Gateway is supposed to communicate with.

Add a device

The interface determines how the Evolo Gateway communicates with the device, for example via KNX, Modbus, MQTT, BACnet, or OPC-UA.

Add an interface

The fields you need to fill in depend on which interface the data point uses.

Add data points

When logging is enabled, the gateway collects values from the data point according to the selected type and interval.
