ActuatorIQ
An AI-powered HVAC diagnostics and building-safety platform combining live actuator telemetry, blockage recovery, anomaly detection, and a 3D digital twin.
Listening to the actuator
A valve actuator’s torque, position, power, and temperature traces reveal far more than whether it is open or closed. ActuatorIQ turns those signals into commissioning evidence, maintenance alerts, and active building-safety actions.
My contribution
I engineered full-stroke calibration, automatic blockage detection, and a retreat–cooldown–retry recovery sequence. I also integrated live Belimo telemetry and setpoint control through a Raspberry Pi 5 and InfluxDB, adding resilient retries for unreliable real-time connections.
The wider team combined this hardware path with anomaly detection, an interactive Three.js building twin, fire-spread simulation, thermal and camera views, valve-sizing analysis, and an AI building doctor.
Outcome
ActuatorIQ won runner-up at START Hack 2026’s Belimo Challenge. The repository includes the web application, live-control utilities, trained fault model, reports, and videos of both normal operation and physical blockages.
