Project Lifecycle

Phased Integration Timeline

We deploy custom installations in discrete, controlled phases to prevent interference with your factory floor activities.

Phase 1: Physical Discovery & Audit

Our engineers run a site check of existing machinery, wiring, and electrical panels.

Phase 2: Architecture & Schematic Drafting

We compile register maps, network scopes, and component blueprints.

Phase 3: Hardware Integration & Firmware Flash

Custom PCB nodes are placed, and bare-metal FreeRTOS firmware is loaded.

Phase 4: Telemetry Aggregation & Ingestion

Edge gateways boot, connecting field devices to secure MQTT brokers.

Phase 5: Cloud Dashboards & Client Handoff

We customize the Aura Dashboard, train operators, and transition to SLA support.

Frequently Asked Questions

No. We use non-invasive hardware taps, ultrasonic clamp meters, and split-core current transformers that install outside cable jacketing or on auxiliary HMI ports. Your factory floors run uninterrupted.
Every edge device executes signed bootloader checks and connects using mutual TLS (mTLS) certificates. Telemetry payloads are encrypted with AES-256 before leaving the edge node.
Our gateways contain local storage caches (up to 8 GB eMMC ring buffer). If a connection drops, data buffers locally and automatically backfills to the cloud once network links resume, preventing telemetry loss.
Operational Backbone

We don't just build systems. We build digital foundations for smarter operations.
