Local, browser-based utilities for working with Acuity nLight SensorView export files. Everything runs on your own machine — no cloud, no accounts, and your exports never leave the PC.
Unofficial community toolkit. Not an Acuity Brands product and not affiliated with or endorsed by Acuity. SensorView, nLight, and MapView are trademarks of their respective owners. Always keep your original export files and review results before importing.
| Tool | Works on | What it does |
|---|---|---|
| Label Editor | .svdb (database backup) or bare sensor.mdb |
Batch-rename device and zone labels from a rename list (in-browser editor or CSV), edit per-device notes, validate against BACnet and SensorView limits, rebuild the backup for re-import. Includes a CLI. |
| MapView Editor | .mvdb (MapView export) |
Edit floorplans in the browser: move/add/remove device markers, draw and reshape zone polygons, rename/add/delete maps, swap floorplan images, auto-optimize PNGs on export. |
Both follow the same pattern:
export from SensorView ──► edit locally ──► rebuilt file ──► import into SensorView
(original file is never modified)
Each tool's README has its own install, usage, and build instructions. Start there — Label Editor · MapView Editor.
Standalone Windows builds are on the
Releases page.
Download the .exe, double-click, and the tool opens in your browser.
Each tool is versioned and released separately — tags label-editor-vX.Y.Z and
mapview-editor-vX.Y.Z, with the version in the filename
(LabelEditor-v1.2.0.exe). See each tool's changelog for what changed:
Label Editor ·
MapView Editor.
You will also see one older relabeler-v1.1.0 release — that is the Label Editor
under its previous name, kept for history. Use the latest release.
The exes are unsigned, so Windows SmartScreen may warn on first run — choose More info → Run anyway. Everything still runs 100% locally.
The Label Editor additionally needs the free Microsoft Access Database Engine (64-bit), installed once per PC. The MapView Editor needs nothing extra.
A SensorView .svdb backup contains a Users table with hashed passwords,
and both file types describe your building layout and device network. These
files should never be uploaded to third-party services. Both tools bind to
localhost and do all processing on your machine.
- Labeling practices — what the Label Editor enforces (BACnet character rules, SensorView column limits, uniqueness) versus what it only recommends, plus a naming format that holds up in a BMS.
.svdbformat and pipeline.mvdbformat and pipeline- Floorplan image guidelines
These tools are free and always will be. If they saved you an afternoon:
- Give to Seattle Children's — to direct it at the team behind these tools, choose Other Area of Support and enter Research Building & Engineering. The giving form cannot be pre-filled from a link, so that step has to be done by hand.
- Buy me a coffee — Venmo, if you would rather say thanks directly.
Neither is expected, and neither buys support or priority on issues.
