After dealing with 43 Matter/Thread devices (all IKEA) and zero visibility into which ones were offline, what their Thread roles were, or how the mesh was structured, I built Matter Saver - a custom component that gives you complete control over your Matter network.
The Problem
Matter devices in Home Assistant have no central overview. After restarts, devices go offline silently. There’s no way to quickly see which node is down, what its Node ID is, how it connects through the mesh, or why it has communication errors. The only option was clicking through 43 devices one by one in the Matter Server UI.
What Matter Saver Does
5 Dashboard Views:
Status - Sortable device table
- 14 columns: Node ID, Name, Area, Product, Status, Thread Role, Neighbors, Children, Parent Router,
Power, Battery, Firmware (with update indicator), Error Count with diagnosis, Last Seen - Click any column header to sort with automatic group headers
- Search field filters across all fields
- Click device name → Action Popup (Ping, Re-Interview, Reset Error Counters)
- Click parent → Route Popup showing full mesh path to HA with RSSI/LQI per hop
Activity Log
- Every online/offline change logged with timestamp
- All manual actions (Ping, Interview, Reset) with results
- Persistent - survives HA restarts
- Filterable
Topology
- Tree view: each Router with its connected End Devices
- Leader first, sorted by number of children
- Quick overview of mesh structure
Mesh Visualization
- Interactive SVG network graph
- HA in center, Routers in circle, End Devices around their parents
- Color coded by role (gold=Leader, green=Router, grey=SED)
- Red glow on devices with >10k errors
- Drag nodes, pan, zoom (mouse wheel)
- Hover for device details
Help
- Full documentation of every column, popup, action, and color code
- Troubleshooting guide
Smart Repair Workflow
The Action Popup adapts its recommendations based on what you’ve already tried:
- First suggestion: Ping to check Thread-level reachability
- If Ping OK → suggest Re-Interview to rebuild Matter connection
- If Interview fails → offer Matter Server Addon Restart button
- If everything fails → suggest physical power cycle
All actions are logged and the repair history is shown per device.
Thread Diagnostics
- Error analysis: CCA errors (channel interference), TX aborts, RX frame errors - with human-readable comments like “strong channel interference, many TX aborts”
- Route tracing: See the exact path from any device through the mesh to Home Assistant, with signal
strength at each hop - RSSI color coding: Green (>-70dBm), Orange (>-85), Red (<-85)
