The KNX Garage node drives a motorised door using dedicated group addresses for direct commands, toggle impulses, hold-open / disable logic and safety sensors. It can optionally re-close the door after a timeout, emit movement / obstruction indicators and report events to the Node-RED flow.
| Purpose | Property | Notes |
|---|---|---|
| Direct command |
Command GA (gaCommand) |
Boolean GA: true opens, false closes. Default DPT 1.001. |
| Toggle impulse |
Impulse GA (gaImpulse) |
Rising edge toggles the door (default DPT 1.017). Used automatically if no direct command GA is supplied. |
| Hold-open override |
Hold-open GA (gaHoldOpen) |
When true the door remains open and the auto re-close timer is cancelled. |
| Disable node |
Disable GA (gaDisable) |
Blocks any command sent by the node while true (maintenance/manual operation). |
| Photocell sensor |
Photocell GA (gaPhotocell) |
Should go true when the beam is interrupted; the node reopens and raises obstruction. |
| Movement indicator |
Moving GA (gaMoving) |
Optional. Pulsed when the node commands movement so other devices can follow the state. |
| Obstruction flag |
Obstruction GA (gaObstruction) |
Mirrors the obstruction state for supervision or alarms. |
All addresses accept custom DPTs if different datatypes are required.
- Enable Auto re-close to start a timer whenever the door becomes open.
- The countdown is cancelled while hold-open or disable are active.
- When the timer expires the node sends the close command (or impulse) and emits an
auto-closeevent.
// Open the door
msg.payload = 'open';
return msg;// Close the door
msg.payload = 'close';
return msg;// Toggle the door state
msg.payload = 'toggle';
return msg;- A photocell
trueduring closing immediately triggers an open command and sets the obstruction flag. - External writes to the obstruction GA update the internal state so dashboards stay in sync.
- Movement pulses can be consumed by lighting, ventilation or alarm logic.
- Injecting
msg.payloadwithtrue,false,'open','close'or'toggle'controls the door from the flow. - With Emit events active the node outputs structured messages:
{
topic: <configured topic or command GA>,
event: 'open' | 'close' | 'toggle' | 'auto-close' | 'obstruction' | 'disabled' | 'hold-open',
state: 'open' | 'closed' | 'opening' | 'closing',
disabled: <boolean>,
holdOpen: <boolean>,
obstruction: <boolean>
}
These events are useful for dashboards, logging or custom automations around the garage door.
