HomeMapper

Your entire smart home network. One view.

HomeMapper builds a unified inventory of every device on your network, scanning HomeKit, Home Assistant, Thread, Matter, and IP at once and correlating them by hardware identifiers.

DISCOVER

Every method runs at once:

• Apple's ecosystem. HomeKit via Apple's framework, plus Thread accessories, Border Routers, and Matter.
• The network itself. Bonjour, subnet scans, and protocols like SSDP/UPnP. Printers, NAS boxes, and other local-only devices show up too.
• Home Assistant. Direct read of your device registry: Matter, Thread, Zigbee, Z-Wave, ESPHome, and MQTT.

When a device appears through several methods, HomeMapper merges it by seven hardware identifiers, not names. Anything uncertain stays as duplicates, never a guess.

YOUR DEVICES, EVERY DETAIL

See devices Apple's Home app can't, and the details it tucks away: manufacturer, model, firmware, serial number, battery, IP and MAC address, and how each device connects, in columns like Connected via, Signal, Channel, and Stability. On iPad and Mac, devices appear as a sortable table; on iPhone, as detail cards. A room-based view groups them by room.

TOPOLOGY MAP

The Topology map draws your smart home the way it is wired: your Thread mesh, from the border routers down to the end devices they carry, and each HomeKit bridge with the accessories behind it. It draws only connections it can measure.

Filter to the whole picture, just the Thread mesh, or just your bridges. Tap a device for its full detail, or tap a connection to see its signal strength and how stable it has been. A red triangle marks a connection that is not working: weak, dropping traffic, or gone quiet. When a device will not report how it connects, HomeMapper says so rather than inferring a connection.

A Health view lists what needs attention on your mesh, worst first: what is wrong, which devices, and one thing to try. Most homes read "Everything looks healthy."

Export the map as a PNG, PDF, or SVG, titled with the home and dated.

It also reads each Thread device's mesh role, and each Border Router's Extended PAN ID and Thread version, hidden in the Home app.

HOME ASSISTANT

HomeMapper scans your Home Assistant instance as deeply as HomeKit. Zigbee, Z-Wave, ESPHome, MQTT: devices HomeKit can't see appear alongside the ones it can. Pick a Primary Platform, and its room names win when a device is known to both.

SETUP CODE VAULT

Every HomeKit, Matter, and Z-Wave device has a setup code on a sticker that fades or gets lost. You need it to pair the device, and again if you reset or move it. No scan can recover one: setup codes never travel over the network.

Save each code while you still have it: scan the QR with the camera, pull it from a photo, or type it in. It reads printed 8-digit codes too, for older accessories without a QR. A room-by-room list shows which devices are still missing one. Have a lot? Export a CSV worksheet, fill it in on a computer, and import it back.

Your codes stay yours: on your device, in your backups, and synced through your own iCloud.

EXPORT AND BACK UP

Export your inventory to CSV, filtered how you want, for Numbers, Excel, or Sheets. Back up your inventory, settings, and setup codes to iCloud Drive or a local folder, and restore on another device.

PRIVACY

You are not the product. Zero ads, zero tracking. Nothing leaves your device unless you send it. No account, and the only login is your own Home Assistant.
