Problem
Building operators often face fragmented control systems where legacy BACnet devices cannot communicate with newer IoT protocols, leading to vendor lock‑in, high integration costs, and limited ability to implement energy‑saving strategies.
Solution
OpenBMS provides a community‑driven, open‑source building management platform that bridges BACnet, MQTT, and other modern IoT protocols while complying with ASHRAE standards such as 223P and 231P. The system enables operators to integrate legacy equipment with contemporary sensors and cloud services without proprietary constraints. Built‑in ASHRAE G36 sequences automate HVAC optimization, delivering measurable energy reductions. Because the software is vendor‑neutral and openly extensible, facilities can customize automation logic, add new device types, and scale deployments while maintaining full transparency and control.
Target Audience
Primary customers are commercial building owners, facilities managers, and system integrators seeking a flexible, standards‑compliant automation platform that can unify existing BACnet infrastructure with modern IoT solutions.
