OPENweb CLOUD
Operate and manage buildings without on-site server infrastructure. OPENweb Cloud provides secure remote access, automatic updates, backups and scalable deployment across multiple locations.
pro.Building Suite for digital monitoring
The pro.Building Suite is an Cloud-based Software for digital monitoring and reporting as well as control of buildings and building data.

Energy monitoring
Monitor energy consumption, compare actual values with targets and generate automated reports.
Digital twin
Bring all building data together in a cloud-based digital twin. Structured information provides a single source of truth for dashboards, reports, and third-party systems while improving transparency.
Customizable dashboards
Create customized dashboards and interfaces to monitor and control HVAC and other building systems from any standard web browser on PC, tablet or smartphone.
Building blocks for efficient BACnet engineering


1. Project planning & BACnet engineering
AMEV-compliant BACnet macro and template libraries cover a wide range of requirements for heating, ventilation, air conditioning and refrigeration applications. Integration libraries for Modbus, M-Bus and KNX help simplify system integration and support efficient project delivery.
During this phase, the system architecture, data points, integrations and BACnet configuration are defined using standardized libraries and engineering workflows.

2. Commissioning & validation
OPEN FXL supports efficient commissioning through optimized workflows, mass parameterization and integrated 1:1 testing. Access to live data points and project information helps verify functionality, improve project quality and reduce engineering effort.
During this phase, controllers, data points and system functions are configured, tested and validated before operation.

3. Building management & optimization
OPENweb provides a scalable building management platform for DEOS BACnet controllers and third-party BACnet devices. Together with BACnet/SC-capable controllers, it supports secure and efficient building operation.
Building performance can now be monitored, managed and continuously optimized through dashboards, alarms and real-time data.
