¶ Introduction
The Weble IoT Universal Gateway communicates with external devices and services through drivers. Each driver implements a specific communication protocol and exposes the data as addresses — protocol-agnostic data points that can be read, written, routed, logged, and monitored.
¶ How drivers work
-
Gateways — a gateway is an instance of a driver configured to communicate with a specific device or service. Multiple gateways of the same driver can run simultaneously (e.g. two Modbus masters connecting to two different PLCs).
-
Addresses — each gateway exposes its data as addresses. Depending on the protocol, the driver either polls the device to fetch values (e.g. Modbus master reading registers), receives values pushed by the device (e.g. BACnet COV, EnOcean radio telegrams), or sends values when written to (e.g. SMTP sending an email).
-
Inter-protocol routing — addresses from any driver can be routed to addresses of any other driver. For example, a Modbus temperature register can be routed to a BACnet analog value, an MQTT topic, and a CSV export simultaneously. The routing engine supports value transformation via JavaScript functions or Blockly visual programming.
-
Logic module — the logic module provides programmable logical circuits for complex automation scenarios using visual block diagrams.
-
Logging & monitoring — any address value can be logged for historical data analysis, energy monitoring dashboards, and trend visualization via the views system.
