Control your KNX intallation via Node-Red! A bunch of KNX nodes, with integrated Philips HUE control and ETS group address importer. Easy to use and highly configurable.

Please subscribe to the Youtube channel and watch the node in action.

Instead of create a knx device node for each Group Address to control, you can import your ETS csv group addresses file. Thanks to that, the knx device node where you selected Listen to all Group Addresses , becomes an universal input/output node, aware of all Datapoints, Group Addresses and Device's name (ex: Living Room Lamp). Just send the payload to the knx-ultimate node, and it'll encode it with the right datapoint and send it to the bus. Likewise, when the knx-ultimate node receives a telegram from the bus, it outputs a right decoded payload using the datapoint specified in the ETS file.

You can work with a mix of knx-ultimate nodes, some with Listen to all Group Addresses checked and some not. You are absolutely free! See this youtube video,

Purpose: answer KNX read requests automatically with the last cached value. Key features: value cache, multi-GA mapping, external updates via Node Pins, activity log. Setup: configure listen/response GA, set cache retention and hook up external update inputs.

Purpose: drive staircase lighting timers with warnings, overrides and resets. Key features: multi timers, prewarning pulses, manual override, start-up readback. Setup: assign command/status GA, choose timer durations and configure override/reset pins as needed.

Purpose: control sectional or tilt doors with impulse commands and safety logic. Key features: impulse drive, state monitoring, safety lock, photocell handling, auto close. Setup: map command/state/alarm GA, define travel times and tune locking or reopen behaviour.

Purpose: bridge KNX with MQTT/REST/Modbus in both directions. Key features: table-based mapping, value scaling, custom acknowledgements, offline buffer. Setup: fill the mapping table, configure external endpoints and define ack/retry strategies.

Purpose: watch KNX traffic directly from the right-hand Node-RED sidebar tabs panel. Key features: 1 s refresh, highlight of fresh telegrams, inline boolean toggles, optional reordering. Setup: pick the gateway, toggle auto-refresh or sorting and apply filters for the GA you care about.

Purpose: inspect every KNX log line in real time from the sidebar without digging into server consoles. Key features: rolling 5 000-line buffer, severity colours, auto/manual refresh controls, one-click copy to clipboard. Setup: open the tab, keep auto refresh enabled (or click refresh when needed) and use the copy icon to export the current log snapshot.

Purpose: translate KNX telegrams into Home Assistant payloads and vice versa. Key features: DPT→entity mapping, discovery helpers, boolean/numeric normalisation, optional acknowledgements. Setup: define target entities, configure conversions/templates and enable Node Pins for feedback paths.
