Connected accessory lost after a reset: check the documented prerequisites in order, then retry only the affected path.
Start with these checks
A reset may remove the device from its old fabric or vendor hub and invalidate automations. First check whether the current controller can still issue a new Multi-Admin sharing code. Document the existing setup before any reset and re-add the device through its supported path.
- Check current owners/fabrics.
- Recover vendor access before recreating integrations.
- Rebuild room/automation associations carefully.
Stop when you find the first unmet requirement. Fix it and try pairing again before changing the next variable.
How to interpret the outcome
Reset recovery may require new registration; multi-admin sharing normally avoids destructive reset.
A failed path does not prove every alternative path is unsupported. For example, a missing direct radio may still leave a separately documented bridge or cloud route.
Avoid these risky shortcuts
- Send QR/PIN to an untrusted support form
