¶ Weble IoT Universal Gateway
The Weble IoT Universal Gateway is more than a simple protocol converter — it is a fully programmable multi-protocol platform for building automation, energy monitoring, IoT integration, and custom applications. It connects to virtually any field device, cloud service, or communication protocol, and provides powerful tools to process, transform, route, and visualize data.
At its core, the gateway uses drivers that communicate with external devices and expose their data as addresses — protocol-agnostic data points. These addresses can then be:
- Routed between any protocols (e.g. Modbus → BACnet, M-Bus → MQTT, KNX → cloud)
- Transformed via JavaScript functions, Blockly visual programming, or the logic module
- Logged for energy monitoring, trend analysis, and historical reporting
- Exported as CSV files, sent via FTP, or pushed to cloud platforms
- Visualized through custom web dashboards built with HTML/CSS/JS
- Alerted via email (SMTP), SMS, or push notifications when thresholds are exceeded
The platform supports 30+ communication protocols out of the box and can be extended with custom drivers on request.
¶ Getting started
| Page | Description |
|---|---|
| First start | Initial setup and configuration of the gateway after first power-on. |
| Gateways | How to create, configure, start, and manage gateway instances (driver instances). |
| Network | Network configuration — Ethernet, WiFi, static IP, DHCP, DNS, firewall. |
¶ Drivers
Drivers are the protocol adapters that connect the gateway to external devices and services. Each driver implements a specific communication protocol and exposes data as routable addresses.

| Drivers overview | Complete list of all 30+ supported drivers organized by category — building automation, IoT & cloud, alarming, and system. |
Key protocols: Modbus, BACnet, KNX, OPC UA, DALI, M-Bus, SNMP, MQTT, HTTP/S, Zigbee, LoRaWAN, EnOcean, SAIA, ADS (Beckhoff), OBIS/IEC 62056, and many more.
¶ Routing & programming
The routing engine is the heart of the gateway — it transfers data between any protocols with optional value transformation. The gateway is fully programmable, offering multiple levels of customization from simple drag-and-drop routing to advanced JavaScript programming.
| Page | Description |
|---|---|
| Routes | The universal routing table — configure data transfer between any two addresses with drag-and-drop, value transformation, conditions, and regular expressions. |
| Route functions (Blockly) | Visual programming with Blockly block diagrams — design routing functions without coding. Supports math, logic, loops, and protocol-specific blocks. |
| Logic Module | Programmable visual logical circuits for complex automation scenarios — timers, comparators, gates, PID controllers, state machines, and custom JavaScript blocks. |
¶ Views & monitoring
| Page | Description |
|---|---|
| Views | Dynamic address views for organizing, monitoring, and visualizing data. Supports dynamic addressing for creating flexible dashboards. |
Any address value can be logged for historical trend analysis and energy monitoring. Data can be exported as CSV files and uploaded to remote servers via FTP for automated reporting.
¶ API
| Page | Description |
|---|---|
| API | JSON REST API and WebSocket interface for reading/writing address values, managing gateways, and integrating with external applications and custom dashboards. |
The HTTP driver also supports custom web visualizations — serve HTML/CSS/JS files directly from the gateway to build custom dashboards that interact with the data through the API.
