Edge AI · <500ms loops No cloud dependency

Intelligence
at the edge.
Always on.

ZedBee's Edge Controller runs Delta-T optimisation, zone-level AI, and HVAC control loops entirely on-site. No cloud round-trip. No latency. No single point of failure — even when the internet goes down.

Latency comparison
Local decisions,
not cloud round-trips.
Cloud-dependent systems add 1–4 seconds between sensor reading and actuator response. ZedBee's edge controller closes the loop in under 500ms — on-site, every time.

What runs on the edge
On-device AI inference
Delta-T optimisation, occupancy-adaptive setpoints, and Water Balancing Algorithms execute entirely on the controller — no cloud API call required.
72-hour offline autonomy
HVAC control, alarm detection, and data logging continue uninterrupted during network outages. All buffered data syncs automatically on reconnection.
Multi-zone parallel control
A single Edge Controller manages up to 64 zones simultaneously, running independent control loops per zone with sub-second response.
Secure local compute
Sensitive building data — occupancy patterns, energy baselines, zone schedules — stays on-premises. TLS 1.3 only on cloud sync.
OTA firmware updates
Zero-touch model and firmware pushes via encrypted tunnel. Rollback support built in — a failed update reverts automatically.
On-edge fault detection
Sensor drift, actuator failure, and threshold breaches trigger local alarms and corrective actions in milliseconds — before the cloud even knows.
