Factory reset
General advice
- First remove the device in your smart home app (controller) so its pairing is deleted there.
- Reset the device as the manufacturer describes – often a reset button or a fixed sequence of power cycles. The exact sequence differs per device; use the manual.
- The device then starts in pairing mode. Set it up again with its QR code or setup code.
Resetting erases the device’s settings and assignments.
