Custom IoT Services: Firmware, Web & Mobile Application Development for System Integrators & Sensor OEMs
We bridge the gap between your sensor hardware, embedded firmware, companion mobile apps, and scalable web platforms - under one roof, with one point of accountability. Predictable delivery, robust IP protection, zero vendor lock-in.
- 100% client IP ownership
- Strict NDA guarantees
- Hardware-in-the-Loop testing
The Controllers, Protocols & Backends We Build On
Our firmware, mobile and web teams work fluently across the microcontrollers, wireless protocols and cloud stacks your products already use.
STM32 · ESP32 · Nordic nRF · NXP · Microchip
Custom firmware development specifically for the microcontrollers your hardware team has selected.
MQTT · BLE 5.x · LoRaWAN · RS485 · Modbus · CAN · I2C / SPI
Sensor-to-cloud data contracts defined and documented before a line of code is written.
AWS IoT Core · Azure IoT Hub · ThingsBoard · SensorVision · Node.js · React / Angular
Dashboards and APIs that plug into your existing ERP, SCADA or third-party systems - or launch faster on our own SensorVision platform.
iOS & Android · Kotlin & Flutter
Field-installer apps for BLE/NFC device onboarding, diagnostics and configuration.
Tailored Engineering Services
Three disciplines, one accountable team - firmware, mobile and web, built to talk to each other from day one.
Embedded Firmware Development
Engineered for reliability, low power consumption and long-term field stability.
- Microcontroller and Microprocessor - ESP-Family, STM32, Nordic Semiconductor, NXP, & Raspberry Pi
- Protocols - MQTT, BLE, LoRaWAN, RS485, Modbus, I2C, ADC, & SPI
- Secure OTA updates - fail-safe dual-bank over-the-air firmware to prevent field bricking.
Companion Mobile Applications
Native-quality iOS & Android apps - built with Flutter or React Native, or Kotlin where performance demands it.
- BLE / NFC provisioning - fast, secure device onboarding and local parameter configuration without a cellular connection.
- Real-time visualisation - live telemetry, sensor status graphs and offline data logging with automatic cloud sync on reconnect.
- Push alerts & diagnostics - threshold notifications, device health checks and remote fault diagnosis from the field.
- Role-based access control - differentiated permissions for field engineers, installers and end-customers.
- App store & release management - versioning, OTA content updates and staged rollouts across your device fleet.
Web Applications & IoT Dashboards
Scalable cloud and web portals - built with React, Angular and Node.js, backed by MongoDB or PostgreSQL - to handle telemetry at volume.
- Custom OEM dashboards - multi-tenant portals for sensor monitoring, device fleet management and remote alerts.
- System integrator API gateways - RESTful and WebSocket APIs feeding your existing ERP, SCADA or third-party platforms.
- Automated alerting & analytics - real-time threshold monitoring via SMS, email and webhooks.
- User & device provisioning - admin consoles for onboarding devices, users and organisations at scale.
- Cloud-native deployment - hosted and scaled on AWS or Azure, containerised with Docker for repeatable releases.
Don't Need a Bespoke Dashboard? Launch Faster on SensorVision
SensorVision is our own foundational IoT platform - built to onboard and connect any device, so you're not paying to rebuild dashboard infrastructure from zero. We're the only provider in this space offering both the platform and the firmware development needed to integrate your devices onto it, removing the usual technical dependency between the two.
- Data acquisition & managementConnect devices via MQTT or REST API; flexible, responsive dashboards per use case
- Device & user provisioningRole-based access control across user groups and device fleets
- Custom rule engine & alertsSet thresholds and receive real-time alerts the moment they're crossed
- Enterprise-grade securityTLS-encrypted network traffic, built-in authentication and authorisation
- Open APIsSecure integration with your mobile apps and other custom-built systems
- Standalone or cloud-hostedDeploy on our cloud or your own infrastructure - transparent costing either way
Still at the idea stage? That's exactly where firmware planning should start.
You don't need a finished prototype to talk to us. Every connected product runs on firmware - so the earlier we're involved, the fewer costly redesigns later. We work alongside your hardware decisions from the concept stage, defining the firmware architecture, communication protocols and cloud data contracts in parallel with your component selection.
- Concept stageFirmware architecture & protocol selection alongside your component choices
- Prototype stageSensor drivers, provisioning app and dashboard built in parallel
- Production stageHardening, OTA safety and full IP handover
Built for System Integrators & Sensor Manufacturers
| Your Challenge | Our Engineering Solution |
|---|---|
| Vendor fragmentation - firmware team blames the web team, web team blames mobile developers when bugs occur. | Single-source accountability. We run firmware, mobile and web in parallel, guaranteeing seamless protocol alignment. |
| Field bricking risk - insecure or unstable firmware updates causing costly physical product recalls. | Fail-safe OTA architecture with dual-bank memory partitioning, so a failed update always falls back to working firmware. |
| Sluggish field onboarding - technicians struggling to configure complex sensors on-site. | Zero-touch provisioning - mobile companion apps configured for single-tap BLE/NFC setup by field operators. |
Our Engineering & Quality Process
Architecture & protocol definition
We define data contracts, payload sizes, binary serialisations and API specs before writing a single line of code.
Firmware & software co-development
Hardware-in-the-Loop (HIL) testing rigs let our app and web engineers work against physical dev kits concurrently.
Validation & stress testing
Simulated packet loss, power interruptions, extreme data loads and battery-consumption profiling.
Handoff & IP transfer
Complete handover of compiled binaries, source code, CI/CD pipelines, build scripts and full documentation.
