IoT development company for connected products and sites
We connect sensors, machines and devices to the cloud, then build the dashboards, alerts and mobile apps that turn their data into decisions your team can act on.
ZedBlu is an IoT development company that builds the software side of connected products and sites: device firmware, connectivity, cloud platforms, dashboards and mobile apps. We help manufacturers add connectivity to existing products, and help operators monitor machines, energy, cold chains, vehicles and buildings in real time.
A working IoT system has many layers, and problems usually appear where they meet. We design the whole chain together: sensors and microcontrollers such as ESP32 or STM32, protocols like MQTT, BLE, LoRaWAN or cellular, ingestion on AWS IoT Core or Azure IoT Hub, time-series storage, and the apps people use every day.
For custom circuit boards and certification, we work alongside your hardware team or a manufacturing partner you choose, while we own firmware, cloud and apps end to end. You keep all source code, device keys and data.
What our IoT & Embedded Development team delivers
Embedded and firmware development
Embedded software development and firmware development in C and C++ for ESP32, STM32, Nordic nRF and similar microcontrollers, with FreeRTOS or Zephyr where real-time behavior matters. We handle sensor drivers, power management for battery devices, local buffering when connectivity drops, and secure boot and encrypted storage of device credentials.
Connectivity and gateways
We choose and implement the right link for your environment: Wi-Fi, Bluetooth Low Energy, LoRaWAN, NB-IoT, LTE-M or Modbus and OPC UA for industrial equipment. Edge gateways on Raspberry Pi or industrial PCs collect data from legacy machines, filter it locally and send only what matters to the cloud.
IoT cloud platforms
IoT platform development on AWS IoT Core, Azure IoT Hub or a custom MQTT broker: device provisioning, authentication with certificates, message routing, rules, time-series storage and APIs. Platforms are multi-tenant where needed, so you can serve many customers and sites from one system with clear data separation.
Dashboards, alerts and analytics
Web IoT dashboard and reporting tools that show live readings, history, maps and device health, with threshold and anomaly alerts sent by app, SMS, email or WhatsApp. Data can feed Power BI or your data warehouse, and machine learning models can flag drift, predict failures or estimate remaining useful life.
Companion mobile apps
IoT app development for iOS and Android in Flutter, React Native, Swift or Kotlin: BLE pairing and Wi-Fi provisioning, live device control, schedules, notifications and multi-user access for families or teams. We test against real hardware and poor connectivity, because companion apps are where customers judge your whole product.
Device management and OTA updates
Tools to manage devices at scale: inventory, remote configuration, logs, health monitoring and over-the-air firmware updates with staged rollouts and automatic rollback if an update fails. These are essential for industrial IoT solutions and consumer devices alike, where sending a technician to every unit is not practical.
What you get
One team across the stack
Firmware, cloud and app engineers work as one team, so device messages, APIs and screens are designed together and integration problems surface early instead of at launch.
Security from device to dashboard
Unique device certificates, encrypted communication, signed firmware updates and role-based access protect your products and data, and reduce the risk of devices being hijacked or cloned.
Built to scale economically
We design message formats, storage tiers and data retention so cloud costs stay predictable as you grow from a pilot of dozens of devices to thousands in the field.
Works with what you have
We connect legacy machines, PLCs and existing sensors through gateways and standard protocols, so you can start collecting data without replacing equipment that still works well.

IoT & Embedded Development: FAQ
What does an IoT development company actually build?
Usually the full chain: firmware on the device, the connectivity layer, a cloud platform that receives and stores data, and the dashboards and mobile apps people use. Some companies bring their own hardware and need only software; others need the complete product. At ZedBlu, we cover firmware, cloud and apps, and work with your hardware team or partner for custom electronics.
How much does IoT development cost?
IoT projects combine several cost areas: firmware, cloud platform, dashboards, mobile apps and hardware. The software side of a focused product, such as a monitoring system with a dashboard and companion app, typically falls within the range of a custom mobile app, about $10,000 to $80,000+ depending on scope, with hardware, connectivity plans and certification costs on top. We quote after a free consultation.
Which connectivity should our device use?
It depends on range, power and data volume. Wi-Fi suits mains-powered devices indoors, Bluetooth Low Energy suits phone-connected products, LoRaWAN suits long-range, low-data sensors on batteries, and NB-IoT or LTE-M suits mobile or remote assets. We can prototype with two options and compare battery life, coverage and running costs before choosing.
What is a realistic timeline for an IoT product?
A proof of concept with off-the-shelf hardware, a basic cloud backend and a simple app typically takes six to ten weeks. A production-ready system with custom firmware, a scalable platform, dashboards and polished apps usually takes four to nine months, depending on hardware readiness, certification requirements and the number of integrations involved.
How do you keep IoT devices secure?
Each device gets a unique identity and certificate, all traffic is encrypted, and firmware updates are signed so devices only accept trusted code. We disable debug ports in production, store secrets securely, apply least-privilege access in the cloud and monitor for unusual device behavior. Security reviews are part of every release, not a one-time task.
