node-red-contrib-dali-sensor 0.3.7
Node-RED node for parsing DALI sensor data and outputting motion and lux
Node-RED dali-sensor
Node
Overview
The DALI Sensor node is designed for use with the Lunatone DALI-2 IoT Gateway to easily filter and process DALI-2 sensor signals inside Node-RED.
It allows you to monitor occupancy (motion), lux levels, and lux alarms from connected DALI-2 sensors, with filtering by short address and instance type/number.
This node is ideal when you want to:
- Extract and use specific motion or lux data from the DALI bus.
- Convert raw DALI sensor frames into clean, meaningful outputs.
- Optionally add automatic delayed Off logic for motion detection.
Features
- Short address filtering — Only process messages from the target DALI-2 device.
- Scheme selection — Supports both:
- Device scheme (instance types)
- Device/Instance scheme (instance numbers)
- Instance mapping — Configure which instance is motion and which is lux.
- Lux setpoint — Auto-generate a Lux Alarm output when lux drops below the threshold.
- Boolean or string outputs — Select
"true"/"false"
or"On"/"Off"
for binary outputs. - Auto-Off option (new) — Motion turns On immediately, then Off after a non-resettable delay.
Outputs
The node has three outputs:
Output Port | Name | Description |
---|---|---|
1 | Motion | Latched occupancy state. Controlled by Auto-Off if enabled. |
2 | Lux Value | Raw lux reading (integer). |
3 | Lux Alarm | Boolean/On-Off depending on whether lux is below the setpoint. |
Auto-Off Feature
When Auto Off is enabled:
- "On" is emitted immediately on motion detection.
- First "Off" starts a delayed turn-off (non-resettable).
- Further Off frames during countdown are ignored.
- An On during countdown cancels the pending Off.
- Default delay is 30 seconds (configurable).
msg.delay
(in ms) on the message that starts the countdown can override the timeout.- Status shows a live countdown.
If Node-RED restarts during a countdown, the node will re-arm the remaining delay and emit Off when it expires.
Configuration
Field | Description |
---|---|
Name | Node label in the flow. |
Short Address | DALI short address of the target device. |
Motion Instance | Instance number/type for motion (for Device/Instance scheme). |
Lux Instance | Instance number/type for lux (for Device/Instance scheme). |
Lux Setpoint | Threshold for triggering Lux Alarm. |
Use Boolean | Output binary states as "true"/"false" instead of "On"/"Off" . |
Auto Off | Enable automatic delayed Off for motion. |
Timeout | Delay in seconds before motion turns Off (default 30). |
