KNX ⇄ MQTT gateway

Connect your KNX installation to the IoT/MQTT world — in both directions.

The problem

KNX drives lighting, blinds, HVAC and building scenes. Mobile apps, IoT dashboards and cloud services speak MQTT / JSON. Getting KNX state out to the cloud — or controlling it remotely — is not native.

How the WBox does it

The WBox publishes KNX group objects as JSON over MQTT and controls KNX from MQTT

The WBox gateway reads and writes KNX group objects and publishes them as JSON over MQTT to a broker. Conversely, an inbound MQTT message controls KNX (switch on, close a blind, change a setpoint).

The transformation converts KNX types (DPT) into JSON and back. Ideal for dashboards, cloud integration, mobile remote control or scenes. Hysteresis and a consistency check keep traffic under control.

What you need

The same principle applies: KNX can also be exposed in BACnet for a BMS.
