Keep Nest Hub on the current Google production software. Google updates the hub automatically and does not provide a user-selectable minimum Matter/Thread firmware for this compatibility path.
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.
- Home Assistant still needs Matter Server even when Nest Hub supplies Thread border routing.
