Hardware and Software Engineering Services for Connected Products
From the firmware running on the board to the platform reading its telemetry, built by one team that owns both ends of the connection. Hygge builds connected products end to end, scoped around what your hardware can do in the field and what the fleet costs to keep running.
What Hygge Builds for Connected Products
The layers a connected product needs, from the microcontroller up to the dashboard someone opens on Monday morning. Most embedded systems product development projects combine three of them, and the audit decides which.
IoT Development
You get the platform behind the devices: ingestion, storage, the apps people work in, and the integrations that put telemetry where the business already looks.
- Telemetry ingestion sized for your fleet and message rate
- Web and mobile apps built for the people who operate the devices
- Device provisioning and identity from the first unit onward
- Integration with the ERP, CRM, or ticketing system already in use
- A running cost per device that holds as the fleet grows
Embedded Software
You get the software that lives on the device: the application logic, the connectivity stack, and the behaviour that has to hold when nobody is there to restart it.
- Application logic on Linux, Android, or an RTOS, matched to the silicon
- Connectivity stacks with retry and backoff that survive a bad link
- Local buffering so a disconnected device keeps its data
- Power behaviour measured against the battery budget you have
- Logs and diagnostics readable from the platform without a site visit
Firmware Development
You get the layer closest to the hardware: bring-up, drivers, the boot chain, and an update path that lets you ship a fix to a device you cannot reach.
- Board bring-up and driver work against your schematics
- Bare metal or RTOS builds sized to the memory you have
- Secure boot and signed images where the hardware supports it
- An OTA path with rollback, so a bad build stays recoverable
- Timing and interrupt behaviour verified on the target board itself
IoT Consulting
You get the decisions settled before the build: connectivity, silicon, platform, and the unit economics that decide whether the product works as a business.
- Connectivity chosen against range, power, and per-device data cost
- Build or buy assessed per layer, with the lock-in stated
- A cost model per device at pilot volume and at scale
- Certification and regulatory requirements identified early
- A phased plan where the first phase proves the riskiest assumption
Industrial IoT
You get machine data off the floor and into a form the operations team acts on, including equipment that predates the network it now sits on.
- PLC, SCADA, and Modbus data read from equipment already installed
- Edge processing so the line keeps running when the link drops
- Condition monitoring with thresholds set by the people on the floor
- OT and IT network separation kept intact
- Dashboards a shift supervisor reads without training
Device Management
You get control of a fleet already in the field: what each unit is running, whether it is healthy, and how a fix reaches it without anyone driving to the site.
- Firmware version and health visible per device across the fleet
- Staged rollouts with automatic rollback on failure
- Credential rotation and remote decommissioning of a lost unit
- Alerts on the failure patterns that precede a site visit
- Telemetry retained long enough to answer a warranty question
Connected Product Work at Hygge, in Numbers
Figures from Hygge's own delivery record behind every embedded system software development project.
What Sends a Team Looking for This
The situations behind most enquiries Hygge scopes for connected products.
The Device Works, the Platform Was Never Built
A prototype sends data to a laptop in the office. Turning that into something a customer can be billed for is a different project, and nobody has scoped it.
Each Vendor Points at the Other
The firmware house says the platform drops messages, the platform house says the firmware sends malformed ones, and each week costs money while they discuss it.
Units in the Field Cannot Be Updated
A defect is known, a fix exists, and reaching the hardware means a van and an engineer per site.
The Cloud Bill Scales With the Fleet
Every new device adds a fixed monthly cost that was never modelled, and the margin per unit shrinks with each deployment.
The Pilot Worked, the Rollout Did Not
Fifty devices behaved. Five thousand surfaced message loss, provisioning bottlenecks, and a database that was sized for the pilot.
The Stack From Silicon to Dashboard
What a connected product runs on at each layer, and the constraint that decides the choice there. Hardware and software engineering services start from this stack.
The firmware layer, sized against the silicon you already committed to. Memory budget, power draw and the timing the product has to hold decide the runtime before a single feature is planned.

Embedded Linux (Yocto)How a Connected Product Gets Built
From a hardware audit to a fleet running in production with an update path behind it. This is how a connected product build runs at Hygge.
Connected Product Audit
Two to three weeks on the hardware, the connectivity options, and the volumes, ending in an architecture and an exact price.
Prove the Risky Layer First
Whichever part carries the most uncertainty gets built first, whether that is power draw on the target board or message throughput at fleet scale.
Build the Device and Platform Together
One team on both sides of the connection, so a protocol change lands on the device and the ingestion service in the same week.
Test on Real Hardware
Timing, power, and recovery behaviour verified on the target board and under the network conditions the deployment will have.
Ship With an Update Path
Staged OTA rollout with rollback, device health visible from day one, and documentation for whoever operates the fleet.
Recognition Running on Hardware in the Field
Aeye Systems: detection on constrained in-vehicle hardware, where a model has to earn every millisecond it consumes.
Where Connected Devices Land by Industry
What a device has to survive in each industry, and how that shapes the firmware and the update path.
Public Safety & Security
Cameras and field devices that keep detecting and queueing events when the network drops, then reconcile once the link returns.
Logistics & Warehouse Automation
Scanners, gates and sensors on the floor talking to the WMS, built so a device reboot costs seconds and the queue survives it.
Aviation
Ground and maintenance equipment where firmware update paths and traceability of every reading are part of the delivery.
Healthcare & Staffing
Connected devices and gateways moving patient data, where encryption at rest, on the wire and on the device is settled in the audit.
Retail & E-Commerce
Kiosks, shelf sensors and in-store hardware reporting to the same backend as the storefront, with remote update built in from the start.
Fitness & Wellness
Wearables and gym hardware syncing to the app, where battery budget and a clean reconnect decide whether people keep using it.
Real Estate & PropTech
Building access, metering and sensor networks feeding a property platform, with commissioning a facilities team can run on its own.
Media & Entertainment
LED walls, capture rigs and interactive installations, where timing and a device that recovers by itself decide whether a venue runs unattended.
Marketing & Creative
Interactive installations and signage where the hardware survives a public space and restarts itself after a power cut.
LegalTech
Evidence and chain-of-custody hardware, where a device log has to hold up in a proceeding and access to it is recorded.
What Changes When One Team Owns Both Ends
A protocol change lands on the device and the platform in the same release, a defect gets fixed remotely across the fleet, and the cost per device is known before the rollout is approved. Hygge builds connected products where the firmware and the platform are written against the same contract. Work priced this way stays predictable across a fleet.

Connectivity Choice
A connectivity choice made against range, message rate, and the per-device data bill.
Platform and Run Cost
The platform architecture, with the running cost modelled per device at pilot volume and at scale.
Update Path
The update path and how a bad build gets rolled back from a device in the field.
Scope and Price
Fixed scope and price, agreed before development starts.
