Industrial IoT Development Company (2026) | Of Ash and Fire

Industrial IoT development with transparent costs. Edge analytics, MQTT/OPC-UA/Modbus, predictive maintenance, brownfield integration. Scope your IIoT project.

Most industrial IoT projects fail not because the technology does not work, but because the cost model breaks before the rollout finishes. We build Industrial IoT systems that scale economically — edge-first architectures that keep cloud bills predictable, brownfield integrations that work with the equipment you already own, and operational outcomes (downtime reduction, throughput, energy savings) that finance teams can actually point to in a quarterly review.

What We Offer

We design and ship end-to-end IIoT systems: sensor and PLC integration on the factory floor, edge gateways and protocol bridging, secure cloud ingestion, time-series storage, real-time dashboards, and the ML models that turn raw telemetry into predictive maintenance alerts and process optimization recommendations. We work with greenfield deployments but spend most of our time on brownfield — plants where the newest piece of equipment is from 2008 and the oldest still runs RS-485 serial.

Key Capabilities

  • Industrial protocol coverage: MQTT and Sparkplug B, OPC-UA, Modbus TCP/RTU, EtherNet/IP, BACnet, and legacy serial protocols. We bridge whatever is on the floor today to a unified data layer.
  • Edge analytics: On-device filtering, aggregation, and inference using NVIDIA Jetson, AWS Greengrass, Azure IoT Edge, or industrial PCs running Docker. You only send the data that matters to the cloud, which keeps egress bills sane.
  • Cloud IoT platforms: AWS IoT Core, Azure IoT Hub, and Google Cloud IoT — including device management, OTA firmware updates, certificate-based auth, and large-fleet provisioning.
  • Predictive maintenance ML: Anomaly detection, remaining-useful-life models, and vibration/thermal signature analysis using scikit-learn, PyTorch, and the time-series databases that actually scale (TimescaleDB, InfluxDB, ClickHouse).
  • Sensor data pipelines: Stream processing with Kafka, AWS Kinesis, or Azure Event Hubs feeding both real-time dashboards and the historical store your data scientists actually want to query.
  • Manufacturing dashboards and OEE: Live OEE (Overall Equipment Effectiveness), shift reports, downtime root-cause tagging, and the kind of operator UI that survives a 12-hour shift on a touchscreen in a noisy plant.

Our Process

1. Discovery & Architecture

We start with a site visit. Walking the floor with operations and maintenance leads tells us more in two days than four weeks of remote calls. We audit existing PLCs, sensors, network infrastructure, and SCADA/historian systems, then produce a costed architecture: how many edge gateways, what protocols, what cloud spend at steady state, and where the highest-ROI use case is for phase one.

2. Design & Prototyping

Before committing to a full rollout, we prove the data path with one line, one cell, or one piece of equipment. We instrument it, send data to the cloud, build the dashboard, and validate that operators and engineers find the output useful. This usually takes 4-8 weeks and gives leadership a real artifact — not a slide deck — to make the go/no-go decision on.

3. Development & Integration

Production rollout runs in waves. Each wave adds equipment, sensors, or sites in chunks small enough to debug and large enough to deliver value. We harden the edge software, build the device management and OTA story, set up monitoring and alerting (Grafana, Prometheus, Datadog), and integrate with your MES, ERP, or CMMS so the IIoT data actually flows into operational decisions.

4. Launch & Support

We do not consider a deployment "done" until operators are using it without prompting. We train maintenance and IT staff, document runbooks, and stay on for the first 60-90 days of full production. Most clients keep us on a usage-based retainer for ongoing model retraining, new use cases, and the inevitable "can we add these 200 sensors to the next plant" conversation.

Industries We Serve

  • Discrete manufacturing: Automotive parts, electronics assembly, and metal fabrication — OEE, predictive maintenance, and quality analytics tied to specific production lines.
  • Process manufacturing: Food and beverage, chemicals, and pharmaceuticals — batch tracking, environmental monitoring, and regulatory reporting (FDA 21 CFR Part 11, GMP).
  • Energy and utilities: Remote asset monitoring for oil and gas, solar, wind, and grid infrastructure, often over cellular or satellite backhaul with intermittent connectivity.
  • Logistics and warehousing: Asset tracking, cold-chain monitoring, and equipment telematics for distribution centers and last-mile fleets.
  • Food and beverage: HACCP-aligned monitoring, cold storage telemetry, and traceability systems that survive both audit and operations.

Service Highlights

1. Transparent cost models, not vendor lock-in surprises

We architect for predictable steady-state cost — edge-first data filtering so cloud egress and ingest bills do not balloon as the fleet grows. You get a per-device, per-month cost projection before deployment, and we revisit it quarterly.

2. Brownfield-first — we work with the equipment you already own

Most plants do not get to rip and replace. We bridge legacy PLCs, RS-485 serial gear, and proprietary protocols into a unified MQTT/OPC-UA data layer using industrial gateways. You do not buy new equipment to start getting value.

3. We measure operational outcomes, not dashboard impressions

Every project starts with a target KPI — downtime hours, OEE percentage points, energy cost per unit, or scrap rate. We instrument the baseline before we deploy and report against it after. If the system does not move the number, we keep working.

Frequently Asked Questions

How much does industrial IoT implementation cost?+
A single-line or single-cell IIoT pilot typically runs $40K-$150K, including edge hardware, cloud setup, and the dashboard layer. Plant-wide rollouts scale to $250K-$2M+ depending on the number of devices, protocol complexity, and ML scope. Steady-state cloud costs usually run $2-$20 per connected device per month, and we model that explicitly before committing to an architecture.
Can you integrate with legacy/brownfield equipment?+
Yes — this is most of what we do. We bridge legacy PLCs, proprietary serial protocols, RS-485, Modbus, and older OPC-DA systems into a modern MQTT or OPC-UA data layer using industrial gateways. You do not need to replace equipment to start collecting useful telemetry.
Should we use edge computing or send everything to the cloud?+
Edge-first, with selective cloud sync. Sending raw sensor data to the cloud is expensive and slow, and many use cases (anomaly detection, control loops, safety interlocks) need sub-second response that round-trips to AWS cannot deliver. We filter and aggregate at the edge and ship the data that matters to cloud storage and analytics.
What is the ROI on predictive maintenance?+
Predictive maintenance typically pays back in 9-18 months for plants with significant unplanned downtime costs. The big drivers are downtime hours avoided, spare-parts inventory reduction, and labor shifted from reactive to planned maintenance. We model the expected ROI from your baseline data before recommending the investment.
How long until we see value from an IIoT project?+
A pilot deployment on one line or one cell delivers actionable data within 4-8 weeks. Operational savings — measurable downtime reduction or OEE improvement — typically show up in the 3-6 month window after pilot, once enough baseline data exists to tune alerting and validate ML models.
