XY Sense launches PremLink for on-premise occupancy data

XY Sense has launched PremLink, an on-premise appliance that sends real-time occupancy data directly into building management systems using BACnet/IP and UDMI. The move targets enterprise and regulated buildings that want faster automation without relying on a cloud round-trip.

Why it matters: - PremLink lets buildings act on live occupancy data locally, which can speed automation and reduce dependence on cloud connectivity. - The appliance is aimed at enterprise and regulated environments where resiliency, security and OT isolation matter. - XY Sense positions the product as a way to connect occupancy intelligence to actual building control, not just dashboards.

What happened: - XY Sense announced PremLink on September 9, 2026. - PremLink is an on-premise appliance that converts occupancy signals into formats a building management system can use. - The device supports BACnet/IP and UDMI output. - XY Sense said the appliance delivers occupancy data to a BMS in under a second. - The launch includes early-access deployments with enterprise customers, including active rollouts at global financial services firms.

The details: - PremLink hosts occupancy status, headcount and percent-occupied as standard BACnet objects on the device, and a BMS can read them or subscribe to change-of-value. - PremLink publishes UDMI v1.5.2-compliant occupancy events to an on-premise MQTT broker. - The appliance supports both virtual space and physical sensor devices. - Local processing lets building systems respond when occupancy changes, without waiting for a cloud round-trip. - XY Sense says the same 2-second sensor updates carry through to the automation layer in under a second. - PremLink keeps feeding the BMS during cloud outages, with local caching and auto-sync on reconnect. - XY Sense Cloud still handles fleet analytics, organization-wide access, sensor health monitoring, calibration at scale and continuous feature delivery. - The security setup includes no inbound connections, dedicated OT network isolation, mTLS sensor-to-gateway encryption and no local CLI or SSH access. - PremLink is a fully managed appliance that XY Sense provisions and maintains. - The appliance is purchased per building with an annual managed service covering infrastructure, remote monitoring, firmware management, technical support and partner liaison.

Between the lines: - The product addresses a long-running gap between cloud-first occupancy tools and on-premise building systems. - XY Sense is betting that building operators want both cloud analytics and local control, instead of choosing one architecture over the other. - The pitch also reframes occupancy data as an operational input for HVAC and compliance use cases, not just a workplace reporting metric. - XY Sense says live headcount can support ventilation control, with potential HVAC energy savings of 20% to 40%. - The company also links the data stream to WELL, ESG and carbon reporting needs. - XY Sense calls PremLink the only enterprise occupancy platform with dedicated on-premise hardware and native BACnet/IP and UDMI output.

What's next: - XY Sense said more information is available at the PremLink page. - The company is offering briefings on real-time occupancy-driven building automation. - XY Sense will showcase the product at PropTech Connect London from September 9 to 11. - The company will continue rolling out early-access deployments with enterprise customers.

The bottom line: - PremLink is XY Sense’s bid to move occupancy intelligence from reporting into direct building control, while keeping cloud analytics in the mix.
