LoRaWAN — Long-Range Wireless Sensors

LoRaWAN sensors transmit data over the 868 MHz radio band to one or more LoRaWAN gateways. The gateway forwards the data to a LoRa Network Server (LNS), which decodes the packets and routes them to Sensor-Online via a secure webhook. This path is ideal for battery-powered sensors deployed across large areas — industrial facilities, agriculture, smart cities, and building automation — where running cables is impractical.

MQTT — Dataloggers & Connected Devices

Dataloggers and smart devices connect via 4G, 5G, NB-IoT, or Wi-Fi and publish sensor readings directly to Sensor-Online's built-in MQTT broker. The platform subscribes to relevant topics and stores incoming data in real time. MQTT is a lightweight protocol optimized for unreliable networks and low-bandwidth devices, making it the protocol of choice for thousands of remote dataloggers in the field.

M-Bus Metering — Energy, Water & Gas

Consumption meters using the M-Bus protocol send data directly to Sensor-Online through dedicated API endpoints — with manufacturer-specific integrations for Elvaco, Piigab, and Mivo. This enables seamless collection of energy, water, and gas consumption data from existing metering infrastructure, without replacing hardware.

REST API — Enterprise System Integration

Enterprise platforms such as Aweeva and OSIsoft PI can read and write data bidirectionally through Sensor-Online's REST API. This allows existing enterprise systems to consume real-time sensor data without architectural changes, and enables Sensor-Online to act as a data hub feeding business intelligence and analytics tools.

SCADA, PLC & Industrial Systems

Industrial control systems — including SCADA platforms and PLCs — connect to Sensor-Online via Modbus TCP and OPC UA. Both protocols support bidirectional communication: the platform can read process values from existing control systems and write setpoints or commands back, bridging OT and IT in a unified data layer.

Build visual flow-based automations: subscribe to MQTT topics, transform payloads, trigger alarms, and push data to third-party systems — all with a drag-and-drop editor. Node-RED runs alongside Sensor-Online and reads sensor data in real time.

Connect Sensor-Online data to 400+ external services using n8n's workflow engine. Trigger Slack notifications when alarms fire, create tickets in your helpdesk system, or push hourly reports to a database — all orchestrated from sensor readings.

Data Storage

Time-series storage optimized for high-frequency sensor data. Retain years of historical measurements and query them instantly.

Visualization & Dashboards

Configurable dashboards with real-time charts, gauges, maps, and tables. Share views with operators, managers, or customers.

Alarm Management

Rule-based alarms with multi-channel notifications — email, SMS, webhook, and MQTT. Escalation rules and acknowledgment workflows included.

Reporting

Scheduled reports delivered automatically to stakeholders. Export in PDF, Excel, or CSV. Ideal for energy reporting and compliance.

Realtime Formulas

Calculate virtual sensors, derived metrics, and KPIs in real time — across multiple physical sensors and channels. No scripting required.

Script Engine

Write custom logic in a built-in scripting environment. Automate complex decisions, data transformations, and integrations beyond standard rules.

REST API

Full REST API for read and write access to all platform data. Integrate Sensor-Online with ERP, BI, CMMS, and any other enterprise system.

Multi-Tenant Architecture

Serve multiple customers or departments from a single installation. Each tenant has isolated data, users, dashboards, and permissions.

Protocol Transformation

Receive data on LoRaWAN, translate to OPC UA. Read Modbus, publish via MQTT. Bridge any protocol combination in your environment.

Full Data Sovereignty & Ownership

When Sensor-Online is installed on-premise, your data never leaves your infrastructure. There is no cloud provider with access to your sensor readings, production data, or energy consumption figures. This is essential for industries operating under GDPR, NIS2, ISO 27001, or sector-specific regulations such as energy, healthcare, and critical infrastructure. You own your data — completely.

Zero Internet Dependency — 100% Local Operation

Cloud platforms fail when the internet fails. An on-premise IoT platform continues to collect, store, alarm, and visualize data even if your internet connection is down for hours or days. For manufacturing plants, energy facilities, and remote installations, local operation is not optional — it is a requirement. Sensor-Online is built around this principle.

Enterprise-Grade Security on Your Terms

With on-premise deployment, your security team controls every layer: network access, firewall rules, user authentication, TLS certificates, and audit logs. You are not sharing a cloud tenant with other customers. You are not exposed to the attack surface of a public SaaS platform. Sensor-Online can operate in fully air-gapped networks, meeting the strictest OT security requirements.

Ultra-Low Latency for Real-Time Control

Cloud round-trips add latency — typically 50–200 ms or more. When sensor data must drive real-time decisions — safety shutdowns, process adjustments, alarm escalations — every millisecond counts. On-premise processing keeps latency in the single-digit millisecond range, enabling true real-time monitoring and closed-loop control that cloud platforms simply cannot match.

Predictable Total Cost of Ownership

Cloud IoT platforms charge per device, per message, or per GB — costs that scale unpredictably as your sensor estate grows. With Sensor-Online on-premise, you pay a fixed license cost, regardless of how many sensors, datapoints, or messages flow through the system. For organizations with hundreds or thousands of sensors, the TCO advantage of on-premise is substantial over a 3–5 year horizon.

Full Customization & Integration Freedom

On-premise deployment gives your team direct access to integrate Sensor-Online with your existing IT landscape — Active Directory, SAP, custom databases, OPC UA servers, and legacy SCADA systems — without going through a cloud vendor's API rate limits or data egress fees. Your integration, your rules.

Multi-Tenant — Perfect for Managed Service Providers

Sensor-Online's multi-tenant architecture allows system integrators and managed service providers to run a single on-premise installation and serve multiple end customers from it — each with their own isolated environment, dashboards, alarms, and user accounts. This dramatically reduces the cost of delivering IoT-as-a-service from your own infrastructure.

OEE monitoring, energy management, predictive maintenance, production KPIs via Modbus and OPC UA.

HVAC, lighting, energy metering, and indoor climate monitoring via KNX, BACnet, and M-Bus.

Grid monitoring, substation telemetry, renewable energy production, and consumption reporting.

Soil sensors, weather stations, irrigation control, and air quality monitoring via LoRaWAN.

Temperature monitoring for cold chains, cleanroom conditions, and equipment status — with full audit trails.

Pump stations, flow meters, level sensors, and water quality monitoring with SCADA integration.

An on-premise IoT platform is software installed and running on your own servers — inside your facility, data center, or private network — rather than on a cloud provider's infrastructure. Sensor-Online.se is an on-premise IoT platform that gives organizations full control over their sensor data, without cloud dependency.

Sensor-Online supports LoRaWAN, MQTT, Modbus TCP, OPC UA, M-Bus, BACnet, and KNX — both for data ingestion and for protocol transformation. The platform can receive data on one protocol and forward it on another, acting as a universal IoT protocol gateway.

Sensor-Online is designed for enterprise scale. Installations with thousands of sensors and gateways are operational worldwide. The platform uses a fixed licensing model — there is no per-device or per-message charge, so cost does not grow with your sensor estate.

Yes. Because Sensor-Online is installed on-premise, it operates entirely on your local network. Data collection, storage, alarming, visualization, and reporting all continue to function even if your internet connection is unavailable. This makes it suitable for critical infrastructure and remote locations.

Sensor-Online.se is developed and supported by Nodeledge AB, a Swedish IoT software company. The platform is actively developed, with installations deployed on-premise at customer sites across Europe and globally.
