Node-RED meets KNX
This node exposes the battery level of a Hue device to KNX and raises an event whenever the value changes.
Start typing the KNX device name or Group Address in the GA field; matching entries appear while you type. Use the refresh icon next to Hue sensor
to reload the list from the Hue bridge after adding new devices.
General
| Property | Description |
|---|---|
| KNX GW | KNX gateway used to publish the battery level (required before KNX mapping fields appear). |
| HUE Bridge | Hue bridge that hosts the device. |
| HUE Sensor | Hue device/sensor providing the battery level (supports autocomplete and refresh). |
Mapping
| Property | Description |
|---|---|
| Level | KNX GA for the battery percentage (0-100%). Recommended DPT: 5.001. |
Behaviour
| Property | Description |
|---|---|
| Read status at startup | On deploy/reconnect read the current battery value and publish it to KNX. Default: “yes”. |
| Node output pin | Show or hide the Node-RED output. When no KNX gateway is selected the output stays enabled so Hue events continue to reach the flow. |
ℹ️ KNX mapping widgets remain hidden until a KNX gateway is selected. This keeps the editor tidy when the node is used only to forward Hue events into Node-RED.
