IoT Platform
What Is an IoT Platform?
An IoT platform connects all layers of an IoT system: Device, Connectivity, Backend, Data Pipeline, Dashboard, App. It is the central infrastructure that captures, processes, stores and visualizes sensor data - while managing devices, users and permissions.
We do not build just one layer - we build the entire platform. As an IoT system integrator, we cover every layer: from device connectivity through the data pipeline to the White-Label interface for your customers.
ThingsBoard

Rule Engine
Privacy-focused
Your IoT Platform - Productive in 12 Weeks
Multi-Tenant architecture, custom dashboards, rule engine and API integration. Let us discuss your requirements.
Features
What We Build - Platform Components
Device Management
Provisioning, fleet overview, OTA updates, rule engine. ThingsBoard as the core for the device lifecycle - from onboarding to decommissioning.
Data Pipeline
MQTT ingestion via Node.js into InfluxDB or TimescaleDB. Data preprocessing, aggregation and forwarding - in real time.
Dashboards & Monitoring
Grafana for ops teams, ThingsBoard dashboards for end customers. 600+ widgets, custom widgets, role-based views.
REST & WebSocket APIs
Open interfaces for mobile apps, third-party integrations and webhooks. API-first architecture for maximum flexibility.
Mobile App
React Native as a natural part of the platform. Device pairing, push alerting, offline sync - one codebase for iOS and Android.
Auth & Multi-Tenancy
Tenant isolation, role-based access control, White-Label. Each tenant sees only their own devices and data.
You got questions? We are here to help!
ThingsBoard
ThingsBoard as Platform Foundation
Open source, multi-tenant, production-proven
ThingsBoard is the most mature open-source IoT platform: device management, rule engine, dashboards with 600+ widgets and native multi-tenant capability. If your platform needs to be multi-tenant, ThingsBoard is the most cost-effective foundation.
We extend ThingsBoard with custom rule chains for your business logic, White-Label interfaces with your branding and API integrations into your existing IT landscape. CE for pilots and single-tenant, PE for SaaS products with customer hierarchy.
More About ThingsBoard
Community Edition (CE)
Free and open source. Rule engine, REST API, MQTT, 600+ widgets. For pilots and single-tenant projects.
Professional Edition (PE)
White-Label, multi-tenant with customer hierarchy, CSV/PDF export, scheduler. For SaaS products and enterprise platforms.
Grafana
Grafana as Platform Foundation
Data-driven monitoring and dashboarding platforms
Grafana is the leading open-source platform for monitoring and data visualization. If your IoT platform is primarily focused on dashboards, alerting and data analysis, Grafana provides the fastest and most cost-effective foundation.
We build custom dashboards on Grafana with embedded panels, Prometheus integration for real-time data, role-based views and automated alerting. Combined with InfluxDB or TimescaleDB, you get a complete monitoring platform without custom dashboard development.
More About GrafanaCustom
Custom Platform Development
Maximum flexibility when no existing system fits
Not every requirement fits into an existing framework. If your platform needs specific data models, custom UI concepts or particular integration requirements, we develop fully custom.
Node.js backend, React frontend, your preferred database. API-first architecture, Docker-based deployment, privacy-focused on German infrastructure. You get a platform tailored exactly to your requirements – without compromises to an existing system.
Multi-Tenant
Multi-Tenant - One Platform, Many Customers
Multi-tenant IoT platforms for SaaS, manufacturers and enterprise
Multi-tenant means tenants receive separate device views, dashboards and user administration on shared infrastructure. Data isolation, roles and scaling are designed and tested for the expected tenant count and workload.
ThingsBoard provides this natively through the Customers/Tenants model with hierarchies. We configure the tenant structure, develop White-Label interfaces and build self-service onboarding - so your customers can register and get started immediately.
SaaS Providers
Offer IoT capabilities to your customers: White-Label, self-service onboarding, separate billing per tenant. You sell the platform, we deliver the technology.
Hardware Manufacturers
Operate a platform for your end customers: each customer manages their own devices, sees only their own data. You maintain oversight of the entire fleet.
Enterprise with Multiple Locations
Branch offices, factories, retail locations - each site as its own tenant. Central management, decentralized usage, cross-site reporting.

Frequently Asked Questions
Frequently asked questions about IoT platform development
A pilot project with Multi-Tenant setup, custom dashboards and 5 - 10 devices starts in the mid five-figure range. Ongoing operating costs are predictable and scale with the number of tenants and devices. After the architecture workshop, you receive a transparent cost overview.
A focused platform with Multi-Tenant, dashboards and API is productive in 10 - 14 weeks. More complex projects with custom widgets, mobile app and multiple integrations take 4 - 6 months. We work in two-week sprints with a demo at the end of each sprint.
The Community Edition (CE) is free and ideal for single-tenant projects and pilots. The Professional Edition (PE) offers White-Label, true Multi-Tenant with customer hierarchy, CSV/PDF export and scheduler. For SaaS products and enterprise platforms, we recommend the PE.
Each tenant has an isolated environment with their own devices, dashboards, users and permissions - on a shared infrastructure. Custom branding available. Scales from 3 to 3,000 tenants without architecture changes.
ThingsBoard scales horizontally: from 50 devices in a pilot to 100,000+ devices in production. The architecture is designed to be scalable from the start - as you grow, we expand the infrastructure by adding additional nodes.
Yes. Via REST API, MQTT and Node-RED, we integrate ERP, CRM, ticketing systems and data warehouses. Bidirectional - the platform receives and sends data. API-first architecture for maximum flexibility.
Self-hosted in German data centers on dedicated servers. Docker-based, monitoring with Prometheus and Grafana, automated backups. No AWS, no Azure - full GDPR compliance without public cloud dependency.
Yes. The mobile app is a natural part of the platform. We develop React Native apps for iOS and Android: device pairing via BLE, push alerting, offline sync and real-time sensor data - from a single codebase.

“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.”
