OpenBMS

Free plan Web

Consider OpenBMS if you want an open-source, on-premise building management system for BACnet- or MQTT-speaking devices, with control logic configured through a visual interface. Look elsewhere if you need real BACnet device discovery now or require semantic modeling, BuildingMOTIF validation, the AI copilot, or G36 demand limiting before those capabilities are available.
