Frequently Asked Questions

Q: Does this screen switch require a neutral wire?

A: Yes, a neutral wire is absolutely mandatory to provide continuous power to the 3.5" HD display and radar components.

Q: Can the radar sensor turn the display off automatically at night?

A: Yes. Through the settings on the screen or via the app, you can customize the proximity wakeup schedule, adjust sensor sensitivity, or dim the screen entirely during sleeping hours.

Q: Can I control other smart devices in my house that are not wired to this switch?

A: Absolutely. While it physically controls 4 wired light circuits, the touch screen interface acts as a scene controller. You can program it to trigger other wireless Tuya/Smart Life devices (like smart curtains, plugs, or air conditioners) over WiFi.
