Figure 8: VPN client configuration on the Web interface
Setting up a VPN client on the LOYTEC device may solve NAT router issues, because no
port forwarding rules need to be configured. The device dials out to the OpenVPN server
running on a public IP and establishes the VPN channel. This VPN channel provides a secure
connection for building automation protocols, such as BACnet/IP, Modbus TCP or CEA-
852. Being part of a VPN the LOYTEC device is also reachable over multi-NAT access
networks, such as LTE.
An alternative method is to enable simple server mode on the LOYTEC device. In this mode,
the device provides an OpenVPN server and allows downloading a client configuration file
from the Web interface. This file can be installed on any OpenVPN client and allows that
client connect to the LOYTEC device over the secure VPN channel. Only one client may
connect at a time.
Data Point Web UI
The LOYTEC device is now tracking information on the source of a written value for each
data point. This information is shown on the data point details Web UI next to the
modification timestamp and can be used for troubleshooting, for example, whether a value
was modified over the Web UI or is written by a local connection.

Make protocol logs more verbose
LOYTEC devices have been improved to decode protocol logs of its supported technologies
to be displayed in a more verbose manner. This makes it easier for Modbus, M-Bus, MP-
Bus, SMI, DALI, EnOcean to analyze communication problems with other third-party
devices. Simply click the Protocol Analyzer link on the statistics Web page of the respective
protocol.
EnOcean over L-STAT
L-STAT devices with EnOcean capability can now be used by LOYTEC devices as remote
EnOcean antennas like a LENO-800 interface. This EnOcean over Modbus feature expands
the air coverage of EnOcean in a multi-room setup. An EnOcean repeater setup that is
cumbersome and difficult to troubleshoot is no longer needed. Simply add EnOcean L-
STATs to extend the wireless reach of the LOYTEC device.
