IoT solutions from sensor to screen.
We build the software for connected devices: the firmware inside the device, the connection to the server, and the dashboards and apps you monitor and control them with. Our hardware partner CulTech designs and manufactures the hardware, so the whole system comes from one coordinated team.

When IoT makes sense
IoT, the internet of things, means devices that measure, control and report on their own: a sensor that tells you when a fridge breaks down, a dashboard with the energy use of every site, a bell that rings to a timetable.
It makes sense when information from a place is valuable and sending a person to check it is expensive, slow or impossible. The hard part is rarely the connection itself. It's everything around it: devices that run for years unattended, remote updates, security and data you can trust. That's where our work is.
What we build
From a single sensor to hundreds of devices in the field.
- 01
Remote monitoring
Temperature, humidity, power and water use, tank levels: data from every site on one dashboard, with alerts when something leaves its normal range.
- 02
Remote control of equipment
Pumps, lighting, doors and machines switched on, off and scheduled from a phone or a computer, with access rights and a log of every action.
- 03
Software for your device
Firmware for ESP32 and STM32, touchscreens and a web interface built into the device itself, as in the RiNGY school bell.
- 04
A platform for connected products
If you make a device, we build the app your customers set it up with and the platform you use to look after every device in the field.
How we build devices that last
The device will run for years somewhere nobody watches over it. We design it for that from day one.
01
Conditions on site
Power, connection range, temperature, who will use the device, and how many years it has to last.
02
A prototype in the field
A working prototype in the real location before any production boards are ordered. If new hardware is needed, CulTech designs it.
03
Secure by default
An encrypted connection, a separate key for every device and signed updates, so nobody can replace the firmware.
04
A pilot batch
A small batch in real use. We collect data, fix the surprises, and only then scale up.
05
Support in the field
We monitor the devices, update them remotely and catch problems before you notice them.
What you get
- Firmware with remote updates
- Secure connectivity and device management
- A web dashboard and a mobile app
- Alerts by email, SMS or in the app
- Hardware from CulTech, or work with yours
- Support for as long as the devices run
Technology from the board to the cloud
Our hardware partner CulTech has worked with the same technology for years, so software and hardware are designed together.
- Devices
- ESP32
- STM32
- Raspberry Pi
- ESP-IDF
- FreeRTOS
- Zephyr
Microcontrollers and operating systems for devices that run around the clock, often on batteries.
- Connectivity
- Wi-Fi
- Bluetooth LE
- LoRaWAN
- MQTT
LoRaWAN reaches for kilometres and runs for years on a battery; MQTT is the lightweight language devices use to talk to the server.
- Industrial protocols
- Modbus
- RS-485
- CAN
For connecting existing machines, controllers and meters.
- Server and data
- PostgreSQL
- Grafana
- Docker
Readings are stored in time order, so you see trends, not just the latest value.
- Applications
- React
- React Native
- Embedded web UI
Dashboards for computers, apps for phones, and an interface the device serves itself, with nothing to install.
Questions about IoT solutions
Can you work with our hardware?
Yes. We write firmware for boards designed by others and build dashboards and apps for existing devices. If the hardware is still to come, our hardware partner CulTech designs and manufactures it.
What happens if the internet goes down?
The device keeps working. We design it to keep its schedules and readings locally and send them when the connection returns. The RiNGY school bell, for example, rings on time for up to 14 days without internet, on its own battery-backed clock.
How are devices in the field updated?
Over the air (OTA), with signed updates that the device verifies before installing. We roll them out to a few devices first, then to all, and if anything goes wrong, the device returns to the previous version.
How secure are connected devices?
Security is part of the design from the start: an encrypted connection, a separate key for every device, no default passwords and only the ports that are needed. We also design with the EU's Cyber Resilience Act in mind, which sets security requirements for products with digital elements.
Do we need the cloud?
Not always. RiNGY runs entirely on the school network, with no cloud and no monthly fees. The cloud makes sense when devices are spread across many places or you want data from every site in one place.
How much does an IoT project cost?
It depends mostly on whether the hardware exists and how many devices there will be. Software for an existing device is a project of a few weeks to a few months. A new product with hardware is planned in stages, starting with a prototype.
