Restart your phone’s Bluetooth before trying the following reset steps.

Curtain 3 / Curtain 4: Press and hold the add button for 15 seconds. Release it when the indicator changes from flashing to a steady light. The reset is complete when the light turns off.

After the reset, check whether the device can connect. Once connected, check that the firmware is up to date. If you need help updating the firmware, go to SwitchBot App → Profile → Feedback.
