Custom hardware and software development

We specialise in a custom development, from the schematic design, PCB and prototypes to manufacturing and testing. We provide custom software for the electronic devices, including mobile, desktop and web applications.

Our achievements

We successfully completed a large-scale of projects with a delivery of 10,000 high-quality devices for remote reading solutions in Vilnius, the capital of Lithuania. Our technology ensures data measurement across the entire city.

Through our converters, more than 1,480,000 meters are connected, with more being added every day.

We implement remote reading projects and IoT solutions worldwide. We focus on water meters, electricity meters and industrial processes, while also the development of additional solutions for various applications.

We are not dependent on any third parties, we develop and manufacture our products in Europe.

Selected projects

We offer the ACRIOS remote reading solutions to all of our customers who want to comply with the EED decree. The solution is quick to install, requires no training and proves to be stable over time.

Jaroslav Brzokoupil, CEO

ACRIOS’ reliable products for remote readings and innovative, fully customizable solutions perfectly complement our expertise in value-added distribution of IoT products and solutions. We are proud to collaborate with a company that shares our commitment to excellence and customer satisfaction.

Ivana Janković Šafarić, CEO

"The remote gas meter reading devices from ACRIOS have proven their reliability and quality of workmanship. We appreciate that all our technical requirements were met and that we received all the necessary documentation and technical support for integration into our information system. We are very satisfied with the cooperation..“

Michal Volný, Head of Technical Services

ACRIOS was instrumental in our success on a large-scale European deployment of the wM-Bus concentrators, helped to solve all of the technical challenges and deliver results within the set deadlines.

Lukas Mickus, Project manager

“The ACRIOS scripting capabilities have provided Netmore with the required solution for solving integrations with MBUS/MODBUS units.”

Jimmy Björklund, Lead Solution Architect at Netmore

We successfully integrated the ACRIOS Data Concentrator into our smart metering project, seamlessly connecting hundreds of meters. The device’s performance and stability have been outstanding, even in challenging environments. The LoRaWAN protocol used by the concentrator ensures strong, reliable signal coverage, even in hard-to-reach areas. We highly recommend the ACRIOS Data Concentrator to anyone looking to enhance their smart metering infrastructure.

Iván Martín Díez, Technical Project Manager

“We were searching for a way that would allow us to connect existing M-Bus and MODBUS meters to our LoRaWAN network and found the solution provided by ACRIOS valuable for these use cases.“

Martin Brunner, Head of Supply Chain at Netmore
