Multi-Vendor Thread Border Router Network Healer and Visualizer for Home Assistant Users Stuck Between Apple, Google, Amazon, and Open Thread Routers That Won't Form One Network
Matter-over-Thread devices fail at commissioning when a household has multiple Thread Border Routers from different vendors that refuse to extend the same Thread network. Home Assistant users keep posting failed-pairing logs and the fix is currently 'unplug everything and pray.' The opportunity is a Home Assistant addon (or standalone tool) that maps the actual Thread network state across vendors, identifies fragmented partitions, and offers a guided heal — plus a watchdog that flags partition splits before they break devices.
Start as a Home Assistant addon that just SHOWS the truth (active partition IDs, which devices joined which router, which routers are refusing to share credentials) and ship the heal flow in v2. The visualization alone will get installs because half the value is being able to say to your spouse 'see, this is why it broke' instead of 'computer says no.'

Everyone affected can identify the problem (partition split, vendor refuses to share) but no single tool maps it across the household. The fix today is folklore on community forums.
