Everything you need to know before building your IoT product
From choosing a development partner and prototyping your first device, to LoRaWAN, BLE, cloud platforms, and industry-specific applications - answered by the engineers who build them.
Choosing an IoT development partner
What to look for before you sign a contract
What does an IoT product development company actually do?+
An IoT product development company designs and builds the full stack behind a connected product - hardware and sensor selection, firmware, connectivity, cloud backend, and the dashboard or app end users interact with - rather than just one piece of it. WeMakeIoT covers this end-to-end, from ESP32 firmware through to a live SensorVision dashboard.
What should I look for in an IoT software development company?+
Three things matter most: end-to-end capability (hardware plus cloud plus application, not just one layer), experience in your specific vertical, and whether the company has an existing platform you can build on rather than starting from scratch every time. A ready platform like SensorVision can cut months off a typical build.
Does WeMakeIoT work with international clients, and does location matter?+
Yes - WeMakeIoT is based in Kozhikode, Kerala, and has delivered projects across 20+ countries including the UK, US and Australia. In practice, location matters far less than it used to: most IoT development is delivered remotely, so the real differences between vendors come down to team experience, whether they have their own platform, and cost structure - not their city.
Hardware & device prototyping
Getting from idea to a working device
How do I make an IoT device?+
At minimum you need a sensor or actuator, a microcontroller to process readings, a connectivity module (Wi-Fi, BLE, or cellular) to transmit data, and a cloud endpoint to receive and store it. Most teams prototype on an off-the-shelf development board before moving to custom hardware.
Do I need to build my own IoT platform to make a device?+
No - most projects use an existing IoT cloud platform to handle device management, data storage, and dashboards, so the custom engineering work is limited to the device itself and the application logic on top of it. This is exactly what SensorVision is designed for.
What's the fastest way to go from idea to a working IoT device?+
Start with a commercial dev board and a managed cloud platform to validate the concept, then move to custom PCB design and firmware only once the use case is proven. Building custom hardware first is the most common cause of delay in early-stage IoT projects.
IoT architecture & cloud platforms
The layers behind every connected product
What is IoT architecture and why does it matter?+
IoT architecture is the layered structure of an IoT system. Getting it right up front determines whether the system can scale to more devices, survive connectivity drops, and stay secure - retrofitting architecture after a large device rollout is expensive.
Perception/Device layer: sensors, actuators, microcontrollers.
Network layer: gateways, Wi-Fi, cellular, BLE, or LPWAN protocols.
Processing/Cloud layer: cloud or edge computing, storage, analytics.
Application layer: dashboards, alerts, business logic.
What is an IoT cloud platform and how do I select one?+
An IoT cloud platform ingests data from connected devices, stores and processes it, and exposes it through dashboards, APIs, or alerts. Key selection criteria: supported connectivity protocols, data ingestion scalability, built-in visualisation, security/compliance, and total cost as device counts grow.
LoRaWAN development
Long-range, low-power wireless IoT networks
When should I choose LoRaWAN over WiFi or cellular for my IoT project?+
LoRaWAN is the right choice when your devices are battery-powered, spread across large outdoor or indoor areas, and only need to transmit small data payloads. It reaches up to 15 km in rural areas and 2–5 km in dense urban environments, with battery life up to 10 years. WiFi suits high-bandwidth, mains-powered applications; cellular suits mobile assets or areas without LoRaWAN coverage.
What is the difference between LoRa and LoRaWAN?+
LoRa is the physical radio modulation technique enabling long-range, low-power transmission. LoRaWAN is the open networking protocol built on top of LoRa that adds device authentication, AES-128 encryption, and network management. WeMakeIoT implements both private networks via Chirpstack and public networks via The Things Network (TTN).
Can WeMakeIoT build a private LoRaWAN network for my site?+
Yes. Private LoRaWAN networks suit industrial sites, large farms, or campuses needing full data sovereignty. WeMakeIoT handles gateway selection and placement, Chirpstack setup, device provisioning, and the cloud pipeline through to your dashboard.
ESP32 & firmware development
Edge hardware, microcontrollers, and firmware engineering
What is ESP32 and why is it widely used in IoT products?+
ESP32 is a low-cost, low-power microcontroller with built-in Bluetooth and Wi-Fi, made by Espressif Systems. It handles sensor data acquisition, edge processing, and cloud communication in a single chip - ideal where cost, size and power efficiency matter.
When should I use ESP32 instead of Raspberry Pi?+
Choose ESP32 for battery-powered, at-scale (10+ units), or harsh-environment deployments - it boots in milliseconds and costs a fraction of a Pi at scale. Use Raspberry Pi when you need Linux, local video/computer vision, or a gateway aggregating data from multiple ESP32 nodes.
How does WeMakeIoT handle OTA firmware updates for deployed devices?+
OTA capability is built into production firmware by default, with rollback mechanisms to prevent devices bricking after a failed update - critical for fleets spread across multiple sites or countries.
Bluetooth Low Energy (BLE)
Short-range wireless for battery-powered devices
What is BLE and how does it differ from Classic Bluetooth?+
BLE is a power-efficient variant of Bluetooth for devices that send small amounts of data intermittently while running for months or years on a battery. Classic Bluetooth is built for continuous, high-bandwidth streaming like audio; BLE trades bandwidth for much lower power use.
What is BLE commonly used for in IoT?+
Indoor positioning and asset tracking, wireless sensor networks, wearable health monitors, and smart-building occupancy beacons. Many products combine BLE for local configuration with LoRaWAN for long-range cloud backhaul.
Is BLE secure enough for enterprise IoT deployments?+
Modern BLE (4.2 and later) supports encrypted pairing and authenticated connections. Overall system security still depends on implementation - secure device provisioning, key management, and regular firmware updates.
SensorVision & IoT platforms
Dashboards, device management, and data integrity
What is SensorVision and how quickly can it be deployed?+
SensorVision is WeMakeIoT's customisable IoT SaaS platform bridging sensors and dashboards - MQTT, HTTP and UDP onboarding, real-time widgets, OTA updates, multi-tenant hierarchy, and alerting. Most deployments go live within days, and it's available white-label for manufacturers.
What is ThingsBoard and when does WeMakeIoT use it instead?+
ThingsBoard is an open-source IoT platform used for enterprise deployments needing a self-hosted solution or deep pipeline customisation. SensorVision is typically the faster, managed option for manufacturers and startups.
What happens when my IoT device stops sending data?+
Silent data gaps are a real operational risk. WeMakeIoT builds data integrity monitoring into deployments - heartbeat checks, last-seen timestamps, and threshold alerts within SensorVision - so a missing device shows up immediately instead of silently.
Industry applications
Building automation, asset tracking, and vertical use cases
What is IoT building automation and how does it differ from a traditional BMS?+
IoT building automation connects HVAC, lighting, access control and fire safety to networked sensors for automatic monitoring and adjustment. A traditional Building Management System relies on proprietary wiring and closed, site-isolated protocols; an IoT-based system layers wireless sensors and open protocols on top, so data from multiple buildings can be aggregated and acted on remotely. Main drivers: occupancy-based HVAC/lighting, predictive maintenance, energy tracking for ESG goals, and falling sensor costs.
What is an IoT asset tracking system and how does it work?+
Connected tags or sensors (BLE, RFID, GPS, cellular) attached to physical assets report location, movement, and condition data to a central platform, with automated alerts for unexpected movement, downtime, or low battery. Most-used in logistics, healthcare equipment, manufacturing, and construction.
What are Sensors-as-a-Service and how do they work for manufacturers?+
A model where clients pay for sensor data and insights on subscription, while the provider handles hardware deployment, connectivity, and maintenance. Sensors send data via MQTT or HTTP to a dashboard such as SensorVision or ThingsBoard for real-time and historical visualisation.
Can WeMakeIoT build IoT-enabled smart vending machines?+
Yes - smart vending units fitted with IoT sensors can track inventory levels, monitor machine health, transmit telemetry to an operator dashboard, and enable cashless payments. This can extend to a fully managed service: remote monitoring, automated restocking and fault alerts, and platform management on a subscription model.
What other niche or industrial IoT applications does WeMakeIoT support?+
Smart cattle tracking: GPS or BLE ear tags/collars monitoring livestock location, movement, and vital signs. Smart temperature monitoring: networked sensors logging conditions in cold storage, labs, or warehouses with instant threshold alerts. IIoT for small businesses: asset management, building automation, energy and inventory tracking via low-cost, subscription-based models, without needing a dedicated in-house IoT team.
