LOYTEC LWEB-900 is building management software for monitoring, operating, configuring, and visualizing LOYTEC building automation systems. It is suited to facilities teams managing HVAC, lighting, alarms, schedules, and trend data across one or multiple sites. The client-server architecture combines a Windows server and client with web-browser access and mobile access through LOYTEC apps for iOS and Android. Graphical building views display dynamic real-time data, while user access controls help govern system access.

Pricing follows a quote-based model, with licensing determined by device and client counts. The standard license includes five LWEB-900 clients and 20 LWEB-802, LWEB-803, or LWEB-APP clients. This structure fits organizations that need to align licensing with a managed building portfolio, but buyers should plan procurement around both the automation device estate and the number of users or client connections required. The software also includes backups and recovery, device configuration, firmware updates, VPN configuration, and reporting from trend logs using templates.

Its strongest fit is a LOYTEC-centered, multi-site environment that needs operational depth rather than a narrowly focused dashboard. Alarm visualization supports acknowledgement, disabling, and notification; hierarchical scheduling can span devices and the server; and trend logs can be presented as charts or tables. Integrations include LOYTEC L-INX Automation Servers, L-ROC Room Controllers, L-GATE Gateways, and L-DALI Controllers, alongside BACnet, DALI, M-Bus, Modbus, KNX, CEA-709, OPC, and XML-DA. Organizations seeking cloud-first deployment or a platform outside an on-premise, LOYTEC-oriented architecture should consider alternatives.
