Modern buildings waste up to 30% of energy due to poorly programmed BMS sequences and unmonitored HVAC control drifts. OxMaint's IoT-integrated CMMS gives facility managers real-time visibility into every setpoint, schedule, and alarm — so your building automation system works as designed, not as assumed. Start a free trial and connect your first BMS site in under 48 hours, or book a 30-minute walkthrough with our building automation specialists.
Why It Matters
BMS Programming Failures Cost More Than You Think
A sequence of operations that was correct at commissioning slowly drifts — sensors age, setpoints get overridden, schedules stop matching occupancy. Most facilities discover the problem on an energy bill or during a tenant complaint, not from a dashboard. Monitoring BMS programming in real time closes that gap before it becomes expensive.

Core Capabilities
What OxMaint Monitors Across Your BMS
01
Sequence Verification
Continuously validates that AHU, chiller, and VAV sequences execute as programmed. Flags deviations from design intent within minutes, not weeks.
02
Setpoint Drift Detection
Tracks supply air temperature, chilled water, and zone setpoints over time. Alerts when values drift outside commissioning-defined tolerance bands.
03
Schedule Compliance
Compares actual BAS runtime schedules against occupancy calendars. Auto-generates work orders when equipment runs during unoccupied hours.
04
Alarm Analytics
Aggregates BMS alarm history, identifies repeat offenders, and prioritizes by energy and comfort impact — so your team acts on what matters most.
05
IoT Sensor Integration
Pulls live data from BACnet, Modbus, and MQTT endpoints directly into OxMaint. No middleware required — connect your BMS in hours, not months.
06
Predictive Fault Detection
Machine-learning fault detection on sensor streams identifies control valve failures, damper faults, and sensor bias before they impact comfort or compliance.

Expert Review
What Building Automation Professionals Say
Most BMS problems are invisible until they're expensive. Continuous sequence monitoring closes that window — facilities that adopt it see energy waste drop by a quarter in the first year alone. The ROI on BMS analytics pays back faster than almost any other building investment.

The biggest issue we see is setpoint override creep — someone adjusts a temperature setpoint manually, it never gets reset, and six months later the whole sequence is fighting itself. Automated drift detection eliminates that entirely. It's not optional for any serious facility operation.

Frequently Asked Questions
BMS Monitoring: Common Questions
OxMaint integrates natively with BACnet IP, BACnet MS/TP, Modbus TCP, and MQTT. LonWorks and proprietary protocols can be connected via a protocol gateway. Most commercial BMS deployments — Johnson Controls, Siemens, Honeywell, Schneider — connect without custom development. Book a session to confirm compatibility with your specific BMS platform and firmware version.
Standard BMS alarms fire when a single point goes out of bounds. Sequence monitoring watches the relationship between multiple points simultaneously — for example, flagging when supply air temperature is within setpoint but discharge damper position is fighting it, which is invisible to point-level alarming. OxMaint's pattern detection catches sequence failures that produce no individual alarm. Try it free to see fault patterns on your own building data.
Yes. OxMaint logs every setpoint, override, alarm acknowledgment, and schedule change with a timestamped audit trail. ASHRAE 90.1 energy compliance reports, LEED Operations and Maintenance documentation, and internal commissioning verification reports can all be exported on demand. Documentation is generated as a byproduct of monitoring — no manual binder assembly required. Talk to our team about compliance reporting for your specific certification requirements.
Most facilities identify their first actionable sequence fault within the first 72 hours of live monitoring. Setpoint drift baselines are established within 7 days. Energy savings are typically quantifiable after 30 days of baseline comparison. The first-month audit alone commonly uncovers 8–15 previously unknown BMS faults across a mid-size commercial building.

Your BMS Is Smarter Than You Think — Start Listening to It
OxMaint turns your existing BMS data into continuous sequence verification, proactive alarm management, and one-click compliance documentation. No rip-and-replace. No new hardware in most cases. Just the visibility your building has always had the data for.
