Hardware and firmware
We develop the whole device ourselves, from board design to production-grade firmware — infrared drivers, analogue inputs, relay outputs and wireless radio alike.

From the field to the cloud,
From the field to the cloud,
secure industrial IoT.
We design LoRaWAN sensors, Modbus/BACnet edge gateways, programmable remote I/O controllers and the cloud platform that manages them — from the circuit board and firmware to the control logic and the dashboard.

What we do
We build all three layers ourselves
IoT projects usually stall in the gaps between layers: one company supplies the sensor, another builds the panel, a third writes the cloud. We design all three in house, so responsibility sits in one place.
Edge control and protocols
Modbus RTU/TCP, BACnet MS/TP and IP, LoRaWAN, MQTT, BLE. Our devices do more than move data: control logic running on PN Controls Studio keeps making local decisions even when the internet is gone.
FIOTX cloud platform
Device registration and authorisation, telemetry, remote commands, alarms and firmware updates over the air. Runs on your own server or on infrastructure we operate.
Product families
A device family built on one platform
Every product shares the same security model, the same factory process and the same cloud protocol. A team that has commissioned one of them already knows the others.
PN Climate HVAC
Multi-point read and control gateway for central VRF and HVAC systems
It reaches the entire system from a single connection point. It reads and writes hundreds of parameters — setpoint, room temperature, mode, fan speed, running state, fault code and energy data per indoor unit — and exposes them to building automation and the cloud at the same time. Instead of fitting a device to every indoor unit, you connect to the system once.
- Access: The whole system from one connection point
- Scope: Hundreds of parameters per indoor unit
- Control: Per-unit setpoint, mode and locking
- Integration: BMS over Modbus and BACnet

Secure by Design
Security is not a feature you add later
A field device runs for years, often somewhere physically easy to reach. That is why we treat security as a product's first decision: every device leaves the factory with its own identity, and that identity cannot be copied.
- A unique identity per device. It is created inside the device during production and never leaves it.
- Signed firmware. A device accepts only updates carrying our signature; unsigned or altered software is rejected.
- Encrypted, mutually authenticated links. Device and platform verify each other, and all traffic between them is encrypted.
- Reversible updates. A new version goes live on trial first; if anything goes wrong the device returns to the working one by itself.
- Traceability. Production, version and service records are kept per device, supporting the trail regulations such as the CRA expect.
- ProductionEvery device leaves the line with its own identity and its test record.
- CommissioningThe device is introduced to the platform; on-site configuration is kept to a minimum.
- OperationMonitoring, alarms and remote control run from a single interface.
- UpdatesNew firmware is rolled out to the field in stages, and can be rolled back.
- ServiceWarranty and fault history follow the serial number.
FIOTX Platform
The layer that manages devices and makes data useful
FIOTX is where PN Controls devices are registered, monitored, controlled and updated. Telemetry arriving over MQTT is stored in a time-series database, device state is managed through a shadow, and LoRaWAN traffic passes through an integrated network server.
Because it is container based, it runs the same way on a customer's own server, in the cloud, or on an industrial PC at the site — you decide where the data lives.
Device management
Registration, authorisation, grouping, configuration and desired/reported state through a shadow.
Telemetry and alarms
High-resolution time-series storage, dashboards, threshold and event-driven alarms.
Remote programming
View and edit the control diagram on the device from a browser; changes reach the device signed and reversible.
FOTA campaigns
Firmware registry, staged rollout, version and failure tracking.
Solutions
Where the devices do their work
From maritime to retail, tank farms to cold rooms — what the goal is in your sector is collected on the sector solutions page. The two figures that defend the budget are usually the same: a lower energy bill and unplanned downtime avoided.
Smart buildings and HVAC
Split and VRF control, room-level comfort and energy savings, integration with existing BMS over Modbus and BACnet.
DetailsEnergy monitoring
Collecting meter and analyser data, consumption breakdown, power quality and load tracking.
DetailsWater and infrastructure
Flow, level and pressure monitoring, pump and valve control at remote stations, leak detection.
DetailsIndustry and Manufacturing
Getting machine data to the cloud, remote I/O, retrofit monitoring and smart connectivity inside control cabinets.

Technology
The languages we speak
If we do not support the protocol you meet in the field, the integration becomes your problem. That is why the product family is built around the common industrial protocols.
| Layer | Supported technologies | Typical use |
|---|---|---|
| Wireless field network | LoRaWAN (Class A / Class C), BLE | Battery sensors, spaces without cabling, commissioning |
| Wired field bus | Modbus RTU (RS485), Modbus TCP, BACnet MS/TP, BACnet IP | Meters, drives, analysers, BMS and PLC integration |
| Backhaul | Ethernet, Wi-Fi, LTE / cellular (PPP) | Gateway uplink with redundancy |
| Application layer | MQTT / MQTTS, HTTPS REST | Telemetry, commands, shadow, FOTA |
| Control logic | PN Controls Studio | Local automation via a graphical diagram |
| I/O | Digital inputs, relay outputs, 4–20 mA, 0–10 V, infrared | Remote I/O, process control, HVAC command |
Let's talk about your project
You may need an off-the-shelf product or a device developed under your own brand. A short call is usually enough to work out what is actually required.
