IoT & Industry 4.0 for Poland's Capital & Tech Hub
Warsaw is Poland's capital, largest city with approximately 1.8 million inhabitants, and the country's dominant financial and technology center. Home to the Warsaw Stock Exchange, a thriving fintech ecosystem, major logistics corridors, and ambitious smart city initiatives, the city drives diverse requirements for connected infrastructure and intelligent building management. With the EU868 frequency band -- identical to Germany -- and the same CET/CEST timezone, Warsaw offers ideal conditions for seamless IoT project delivery from our base in Germany. No time zone barriers, no frequency reconfiguration, no collaboration friction.
Sensors, gateways, data platform, business application, identities, interfaces, and operations are planned together. Additional sites, cloud services, or local edge systems can then build on the same architecture model.
Remote Delivery from Germany
Remote delivery with a dedicated technical contact, structured project communication, and coordinated commissioning.
24/7 Platform Monitoring
Automated 24/7 monitoring with alerts. Human response times and support coverage follow the selected service level; overnight P1 response is included with Production and Critical.
Dedicated Contact Person
No ticket system, no call center. Your direct line to the engineer managing your IoT instance for Warsaw -- with seamless communication in the same timezone.

The examples illustrate possible application patterns. Architecture, radio coverage, device selection, data model, and operating scope are assessed for the specific project.
One system instead of isolated silos
From measurement to an operated business process
Value does not come from a single sensor or dashboard. What matters is an end-to-end data path with clear interfaces, access rules, and operating responsibilities.

Technical foundation
The Technology Behind Your IoT Infrastructure
We rely on a proven open-source stack: ChirpStack as LoRaWAN network server (configured for EU868 -- the same frequency band used in both Poland and Germany), ThingsBoard for device management and dashboards, Grafana for real-time visualization, and Node-RED for data routing. All hosted on hardened Linux servers with automatic backups and security updates. The identical EU868 frequency means hardware configured for German deployments works in Warsaw without modification.

Hardware Expertise with Milesight
We rely on Milesight and know the product portfolio inside out - from environmental sensors to LoRaWAN gateways to industrial controllers. We advise, source and integrate the right hardware for your use case.
Milesight hardware ships worldwide - we deliver pre-configured and firmware-updated, ready to deploy.
We also work with hardware from other manufacturers - whether proprietary or open-source. What matters is that it works reliably and integrates into our stack.
Project path
From a concrete use case to an operating system
The initial step remains manageable. Device count, architecture, integrations, and operating responsibilities are defined only after the technical assessment.
01
Assess the use case
Capture measurements, sites, users, existing systems, alert paths, and the expected business outcome.
02
Plan architecture and pilot
Combine radio path, devices, platform, data model, interfaces, and security requirements in a testable design.
03
Integrate platform and data paths
Provision devices, configure services, process data, and connect dashboards or business applications.
04
Operate and expand
Agree monitoring, updates, backups, and response paths, then add further sites or capabilities in a controlled way.
Region and scale

Answers about our IoT services, remote delivery, LoRaWAN deployment, and project process for Warsaw.
Themen
Remote Delivery & Collaboration
We support the IoT initiative from requirements analysis through architecture, hardware selection, platform setup, and sensor integration to custom dashboards and managed operations. WZ-IT prepares gateways and sensors
Germany and Poland share the same CET/CEST timezone -- there is zero time difference. This means full overlap during business hours for meetings, live debugging sessions, and project coordination. Platform monitoring runs 24/7 with automatic alerts; human response times follow the selected service level.
Smart Office & Finance
Office towers and bank headquarters in Srodmiescie and Wola benefit from occupancy monitoring, energy consumption tracking, HVAC optimization, and indoor air quality management. LoRaWAN sensors provide building-wide coverage without interfering with existing IT infrastructure. ThingsBoard dashboards give facility managers real-time visibility across entire building portfolios.
LoRaWAN-based energy meters and sub-meters are installed per floor or zone. Data flows to ChirpStack and is visualized in Grafana dashboards showing consumption patterns, peak loads, and anomalies. Automatic alerts notify building managers when energy usage exceeds defined thresholds -- enabling proactive cost management.
Logistics & Supply Chain
Warehouse environment monitoring (temperature, humidity for cold chain compliance), asset tracking across distribution centers, door and access monitoring, and loading dock utilization tracking. LoRaWAN provides cost-effective coverage across large warehouse complexes in Praga and Targowek without recurring cellular data costs.
LoRaWAN-based trackers attached to pallets, containers, or vehicles transmit location and status data to gateways positioned across the facility. ThingsBoard dashboards provide real-time asset maps, movement history, and dwell time analytics. Geofencing alerts notify operators when assets enter or leave designated zones.
Platform & Technology
ChirpStack is an open-source LoRaWAN network server that manages gateway and device communication. We use it because it provides full control over the network stack, supports EU868 frequency configuration for Poland and Germany, and avoids vendor lock-in. Combined with ThingsBoard for device management and Grafana for visualization, it forms a proven, flexible IoT platform.
Yes. Poland and Germany both use the EU868 frequency band (863-870 MHz) for LoRaWAN. Hardware configured for German deployments works in Warsaw without any modification. This eliminates frequency-related configuration effort and simplifies hardware procurement within the EU.
Getting Started & Terms
The timeline depends on the platform, device count, radio planning, data paths, integrations, and operating model. After the technical assessment, you receive a rollout plan with prerequisites, dependencies, and milestones.
Yes. We design and develop multi-tenant platforms for multiple locations across the Warsaw metropolitan area -- with location-specific dashboards, role-based access controls, and custom alerting logic. Ideal for enterprises managing office buildings, warehouses, and urban infrastructure from a single pane of glass.

“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”
