Troubleshooting checklist
- Confirm Nest Hub and Home Assistant are on the same IPv6-capable LAN with mDNS multicast available.
- Check whether Google Home and Home Assistant show separate Thread networks before resetting the accessory.
- Share the Matter accessory with a fresh multi-admin code; do not try to pair the Nest Hub itself to Home Assistant.
