Touch-Plate Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP) BACnet points list
Updated 12 November 2026
The Aura Interior Sensor is a ceiling light-level and motion sensor that is its own BACnet MS/TP device. It reports the light level in lux, four lux-threshold flags and a motion flag; thresholds, hysteresis, delays and the occupancy mode are Analog Values the BMS can adjust.
This page lists 18 BACnet objects for the Touch-Plate Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP) — 12 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Touch-Plate’s own free documentation, linked below.

BMS integration notes: Touch-Plate Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP)
Read AV 1 for the light level and BI 5 for occupancy; the threshold flags BI 1-4 are ready-made daylight switches. Inputs support COV subscriptions, so subscribe rather than poll.
Minimum points to map
The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.
| Object | Name | Why | Access |
|---|---|---|---|
| BI 5 | Motion Detected | Occupancy, 1 = room occupied | Read |
| AV 1 | Light Level | Measured light level, lux | Read |
| BI 1 | Light Threshold 1 | 1 = light above threshold 1 (AV 4) | Read |
Network setup
- MS/TP MAC address, baud rate and I/O configuration are set with DIP switches; AV 11 and AV 12 read or change them.
- MS/TP master at 9600, 19200, 38400 or 76800 baud.
- Device instance defaults to 68301-68500 and can be changed through AV 1003.
Watch out for
- Setting AV 10 Occupancy Sensor Mode to 0 makes the sensor ignore motion.
Touch-Plate Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP) BACnet objects
Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.
Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes
- Object list from the 2-page PIC statement "Table of Objects". There is no read/write column; the setting AVs are marked W and the inputs R.
- Object names are kept as printed, including "Hysterisis" and the paired threshold names ("Lux Threshold 1/2" sets the BI 1 threshold).
- The Aura Exterior Sensor AUR-EB-FX PIC sheet prints the same table minus BI 5 Motion Detected and AV 8-10.
Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Touch-Plate Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP)
How many BACnet points does the Touch-Plate Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP) have?
This list has 18 BACnet objects: 13 analog values, 5 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Touch-Plate Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP) BACnet points are writable?
12 of the 18 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done. The source has no read/write column, so this is inferred from object type.
Where is the official Touch-Plate Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP) BACnet documentation?
The source is PIC Statement - Aura Interior Sensor, published free by Touch-Plate at https://touchplate.com/wp-content/uploads/product-documents/Components/Sensors/Aura-Interior-BACnet-PIC-Sheet.pdf.
What are the minimum BACnet points to integrate the Touch-Plate Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP)?
Start with BI 5 Motion Detected (Occupancy, 1 = room occupied); AV 1 Light Level (Measured light level, lux); BI 1 Light Threshold 1 (1 = light above threshold 1 (AV 4)).
How do I check these points on the real Aura Interior Sensor AUR-IB-FX light level and occupancy sensor (BACnet MS/TP)?
Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
