An integral part of the LOYTEC hardware is a configurable firewall, which can be enabled and configured over the built-in web server, over OPC XML‑DA, or OPC UA. The built-in web server is accessed via the secure HTTPS protocol. A pre-installed certificate allows a quick setup and can later be replaced by a locally generated certificate or by a certificate issued by a certification authority. Data communication is encrypted by TLS encryption methods. The use of secure certificates prevents man-in-the-middle attacks. Furthermore, the OPC UA server provides a secure alternative to OPC XML‑DA. It uses the installed server certificate and authorizes OPC clients by certificates.

LOYTEC devices can also be operated as part of a virtual private network (VPN) based on the OpenVPN technology. In a VPN setup, the device connects to a VPN server with an authenticated VPN certificate. The VPN provides a secured network channel that can carry any of the IP-based protocols. In combination with a VPN server on a public address, VPN devices can be accessed without having a public address. This provides a secure alternative to NAT forwarding and makes secure access to remote sites very simple. In combination with LWEB-900, setting up a VPN on the device is as easy as entering the LWEB-900 VPN project PIN code. LWEB-900 fully automatically generates the VPN certificates and enrolls the device in its own VPN.

LOYTEC multisensors and LOYTEC controllers with Bluetooth interface use BLE for asset tracking. In addition, LOYTEC multisensors are able to advertise either standard beacons with configurable identifier like iBeacon or EddyStone-UID which allows them to be perfectly integrated in indoor navigation systems. The L-WEB beacon enables secure room operation using the LWEB-App, as it restricts access to LWEB-900 functions to the close vicinity of the L-WEB beacon.

The corresponding LOYTEC devices require the LTE-800 Interface connected to a USB port, which provides for an easy and simple solution to connect remote sites together via a VPN network and expose defined on-site services. The LTE interface can also be used to send SMS directly. Typical LTE applications include remote management, energy monitoring, site visualization, SMS alarm notification.

LOYTEC devices with a BACnet interface can also use BACnet trend log objects for historic data recording. These objects can be accessed over the BACnet network and expose trend data to other BACnet devices and operator workstations (OWS). Each BACnet trend log object can record data for a single data point only. The recorded data point is limited to the BACnet technology, either to a local BACnet object or to a remote BACnet object (configured by a client mapping).

LOYTEC devices for LonMark Systems (CEA-709) use generic trend logs. There exists no LonMark functionality that allows transparent LonMark access to trend log data.

Trend log data of the different trend log objects can be displayed by LWEB‑900, LWEB‑802/‌803 and L-VIS. Trend data can be viewed either in a table view or in a trend graph. In addition, the LWEB‑900 server allows long-term storage of the historic trend data. For doing so, the recorded data is periodically read out from the device and stored in a database. If no permanent IP connection should exist between the L-WEB server and the respective LOYTEC devices, the devices can be configured to send trend data automatically as an e-mail attachment to the L-WEB server. Trend data can also be exported as a CSV file (via FTP access), or stored to SD card or USB memory, if the device supports it.

For certain applications, historic values of a given base data point, both recent and far into the past, can be of interest. This can be accomplished with historic filters. They allow processing historic values of the base data point according to a filter function. One or more such functions can be defined per base data point. The result of the historic filter is written to “historicFilter” property relations. For each historic filter function, a time period can be defined at which the base value is sampled, e.g., every first of the month at midnight, and how many samples ago. Historic filters can be created for any analog, binary, or multi-state data point. It is not necessary to create a trend log.
