The Client

BK, a.s. is a Slovak building technology and facility management company founded in 1995, headquartered in Piešťany. Since 2021, the company has been owned by ZSE Energia — Western Slovakia Energy, one of the country's three major electricity distribution companies. With 50-99 employees, BK provides technical facility management, electrical installations, photovoltaic systems, HVAC, and building renovations to major institutional clients including Slovak Telekom, UniCredit Bank, Slovnaft, and Tesco.

The ZSE Energia ownership is strategically significant. As an energy utility expanding into smart city services, ZSE can leverage BK's facility management network to deploy IoT infrastructure — including smart parking — across the commercial properties and municipal facilities that BK already maintains.

The Challenge: Demonstrating a Complete Smart Parking Solution for a Facility Management Portfolio

BK manages hundreds of commercial properties across Slovakia. Parking — particularly permit-controlled parking at offices, retail centres, and institutional campuses — is a persistent pain point for facility managers. Traditional approaches (barrier gates, manual enforcement, or unmanaged open lots) create either high maintenance costs, poor user experience, or no data at all.

To offer smart parking as a service within its facility management portfolio, BK needed a reference deployment: a complete, working system that demonstrates every component of digital parking management — including parking enforcement software workflows and real-time guidance signage — to its existing client base.

The Solution: Full-Stack Turnkey Deployment with Every Fleximodo Component

BK's November 2023 order is remarkable not for its size (5 parking spaces) but for its completeness — this is every Fleximodo component type deployed simultaneously.

The deployment included:

• 5 × IoT Parking Sensor Standard (LoRaWAN, in-ground) — Parking occupancy detection for each monitored space
• 5 × IoT Permit Card (BLE) — Vehicle identification cards for authorised parkers, detected by sensors via Bluetooth Low Energy, forming the basis of a lightweight parking enforcement software workflow
• 5 × Parking Guidance Display (Flip-Dot) — Solar-powered digital parking signage showing real-time availability, one display per monitored space or zone entrance
• LoRa Gateway — On-site network infrastructure connecting sensors to the IoT Hub
• IoT Hub (48-month OPEX) — Managed backend service, accessible through Fleximodo's CityPortal login, contracted for the full 4-year term
• Installation and initial setup — Turnkey deployment including hardware mounting and system provisioning

A 1:1:1 ratio of in-ground parking sensors to Permit Cards to displays — plus gateway and managed backend — means BK deployed a complete showcase of every Fleximodo capability in a single 5-space installation. This is not a parking lot; this is a demonstrator. Each of the five spaces shows a prospective client every digital parking function: the sensor detects whether the space is occupied, the Permit Card identifies whether the vehicle is authorised, and the Flip-Dot parking guidance system shows the space status in real time.

The 48-month contract aligns with BK's facility management contract cycles. By committing to 4 years of OPEX, BK can bundle smart parking into its existing multi-year facility management agreements — offering clients a parking management fee that includes hardware, software, connectivity, and maintenance as a single line item.

Fleximodo IoT Parking Sensor Standard In-ground 2.0: Technical Profile

Specification	Detail
Detection method	3-axis magnetometer + nanoradar (dual detection technology)
Detection accuracy	99.96%
Dimensions	115 mm diameter, height 64 mm
Weight	390 g
Battery	3.6 V, 13-19 Ah (6-year operational lifetime)
Connectivity	LoRaWAN Class A/B/C
Ingress protection	IP68
Impact resistance	IK10
Weight endurance	Up to 8 tonnes
Operating temperature	-40 to +85 °C

These in-ground parking sensors combine a magnetometer parking sensor core with a radar parking sensor channel — Fleximodo's dual detection technology — and use automatic temperature compensation to keep their 99.96% detection accuracy stable across Slovakia's full seasonal range, from winter frost to summer asphalt heat. Without this compensation, temperature-driven drift in the magnetic-field reading could register as a false vehicle arrival or departure; with it, BK's demonstrator can show prospective clients consistent, year-round parking occupancy detection rather than a system that needs seasonal recalibration.

Fleximodo IoT Parking Guidance Signage: Technical Profile

Frequently Asked Questions

What is BK, a.s.? BK is a Slovak facility management and building technology company founded in 1995, headquartered in Piešťany. Since 2021, it has been owned by ZSE Energia (Western Slovakia Energy). With clients including Slovak Telekom, UniCredit Bank, and Slovnaft, BK provides technical facility management, electrical installations, photovoltaics, and building renovations. Smart parking represents an expansion into IoT-enabled services for its existing commercial property portfolio.

What makes this deployment unique among Fleximodo orders? This is the only known order combining every major Fleximodo component in a single deployment: in-ground parking sensors, Permit Cards, Flip-Dot parking guidance signage, a LoRa gateway, and a managed IoT Hub under a 48-month contract. The 5-space scale with full-stack equipment suggests a demonstrator installation designed to showcase complete smart parking capability, including parking enforcement software workflows, to BK's facility management clients.

Can Fleximodo smart parking be bundled into facility management contracts? Yes. BK's 48-month OPEX commitment demonstrates how smart parking integrates into existing facility management agreements. The predictable monthly backend cost structure, managed through Fleximodo's CityPortal, allows facility managers to include parking intelligence as a standard service line — bundled alongside HVAC, electrical maintenance, and security within a single multi-year contract.

What is automatic temperature compensation and why does it matter for this deployment? Automatic temperature compensation is a calibration technique that continuously adjusts a magnetometer parking sensor's baseline magnetic-field reading as temperature changes, so seasonal heat or cold doesn't get misread as a vehicle arriving or leaving. Fleximodo's in-ground sensors use it to hold 99.96% detection accuracy year-round, which is essential for a reference deployment meant to demonstrate consistent, reliable parking occupancy detection to prospective facility management clients.
