Temperature, leaks or motion, measured around the clock.
Software on the device filters readings and spots problems.
A gateway sends readings to the cloud and takes updates back.
The right person gets an alert on their phone.
Embedded Systems & IoT
Smart devices with firmware you can rely on.
We write the software that runs inside devices, known as firmware, and connect those devices to sensors, apps and online systems so they can share data.
What you get
01Dependable firmwareDevice software that starts reliably, handles faults and can be updated.
02Connected devicesWi-Fi, Bluetooth, cellular or long-range radio, chosen to suit the setting.
03Data you can useReadings delivered to a dashboard, app or your own business systems.
How we deliver
Four stages, each ending with something you can see and review before the next one starts.
01
Scope
We define what the device must sense, decide and report, and how it connects.
02
Architect
We choose the processor, radio and software structure to fit power and cost.
03
Develop
We write and test firmware on real hardware, alongside any app or cloud work.
04
Deploy
We support first installations, monitor devices and release updates.
What we buildOur embedded and IoT capabilities
Firmware development
Software for microcontrollers that controls the device and its hardware.
Discuss thisSensor integration
Reading temperature, motion, location and other sensors accurately.
Discuss thisWireless connectivity
Choosing and setting up the right radio link for range, power and cost.
Discuss thisLow-power design
Firmware and hardware choices that make batteries last as long as possible.
Discuss thisOver-the-air updates
Updating device software remotely, so fixes do not need a site visit.
Discuss thisDevice security
Secure boot, encrypted links and safe handling of keys and credentials.
Discuss thisCloud and app connection
Sending device data to online services, dashboards and mobile apps.
Discuss thisFleet management
Tools to monitor device health and manage many units in the field.
Discuss thisDrive Pulse
Fleet operators find out about vehicle faults only when a driver reports them or the vehicle is in the workshop.
Selected work · Drive PulseAnimated illustration
IoT and fleet management: remote vehicle diagnostics
What we built
- A device and platform that connect to each vehicle's on-board diagnostics (OBD) port
- Engine data and fault codes read remotely
- One dashboard for the whole fleet
What it changed
Fleet managers track vehicle health from one dashboard and plan maintenance before a breakdown.
Also delivered: Smart Hail Guard, AI hail detection on field devices, and Ensemble Smart Lighting, lighting control with the AI running on the device.
Delivered by Hoki and its engineering partners. Product and client names belong to their owners.

Frequently asked questions
How is the cost of an IoT project set?
It depends on the device, the number of units and how much app or cloud work is involved. We scope the project after a discovery discussion and usually suggest starting at one site before a wider rollout.
Can you connect devices to our existing systems?
Yes. We can send device data to your current software, databases or reporting tools, as long as they offer a way to receive it, such as an API.
How do you keep connected devices secure?
We use encrypted connections, secure start-up, unique device credentials and signed updates, and we review security as part of each release.
Who looks after the devices once installed?
We offer ongoing support, monitoring and firmware updates under an agreed arrangement, or we can hand everything over to your own team.
