Factory Reset

To reset the device to factory defaults, long press any desired button for approximately 5 seconds until the Wi-Fi LED indicator flashes in a cycle of two short and one long flash. Release the button; the reset is successful, and the device enters quick pairing mode (Touch).

Important: Reset the switch to factory defaults if you want to connect to a different Wi-Fi network, then reconnect to the network.

RF Remote Controller Pairing

The switch supports pairing with a 433.92MHz RF remote controller for turning devices on/off. Each channel can be learned independently, providing local short-range wireless control separate from Wi-Fi.

Pairing Method:

Long press the touch button you wish to pair until you hear a "beep" sound, then release. Press the corresponding button on the RF remote controller. You will hear another "beep" sound upon successful pairing. Repeat this method for other buttons.

Clearing Method:

Long press the touch button you wish to clear until you hear two "beep" sounds, then release. Press the corresponding button on the RF remote controller. You will hear a "beep" sound upon successful clearing. Repeat this method for other buttons.

Common Problems

Q: Why is my device showing as "Offline"?

A: A newly added device requires 1-2 minutes to connect to Wi-Fi and the network. If it remains offline for an extended period, check the status of the blue Wi-Fi indicator:

Blue Wi-Fi indicator flashes once per second: The switch failed to connect to your Wi-Fi. Possible causes include:
- Incorrect Wi-Fi password entered.
- Device is too far from the router, or environmental interference. Move the device closer to the router. If unsuccessful, re-add the device.
- 5G Wi-Fi network is not supported; only 2.4GHz is supported.
- MAC address filtering is enabled on the router. Disable it.
Blue indicator flashes twice per second: The device is connected to Wi-Fi but cannot connect to the server. Ensure your network is stable. Frequent double flashes indicate an unstable network, not a product issue. If the network is normal, try pressing the "Reset Button" or power cycling the switch.
