Zemismart ZN-USC1U-HT công tắc rèm Zigbee thanh trượt cảm ứng, mặt kính (kích thước Mỹ)
Please note: this switch has a 120 × 72mm plate for US and Latin American (4 × 2) wall boxes. It doesn’t fit standard UK back boxes. A Tuya Zigbee hub is required (not included).
In the UK? Our 86mm Zigbee curtain switch (ZN-LC1E) fits standard UK back boxes.
The Zemismart ZN-USC1U-HT is a glass touch wall switch for mains-powered curtain and roller shutter motors, with a touch slider that sets the exact position right on the wall. Slide to 25%, 50% or 90% open, or tap open, pause or close. Through a Tuya Zigbee hub, you can also control it from the Tuya app, by voice with Alexa or Google, and with Siri in Apple Home via a Zemismart M1 Pro or M6 hub.
Prefer Matter and Apple Home without a Zigbee hub? See the ZM20A. Just need open, pause and close? See the simpler ZN-UC1U.

Set the position with a touch slider
Slide your finger along the light bar to open the curtains to any position from 0% to 100%. The bar lights up to show how far open they are. You can also set the position in the app.

Voice control
Say “Alexa, open the curtains” or “Hey Google, close the blinds”. With a Zemismart M1 Pro or M6 hub, you can use Siri and Apple Home too.


Tuya app control and calibration
In the Tuya or Smart Life app, you can open and close the curtains from anywhere, reverse the motor direction and calibrate the travel time so percentage positions are accurate. Share control with the rest of your household, and group all your blinds together.

Schedules and scenes
Close the curtains at 22:30 for bed, open them at 7:30 to wake you up, or link them to sunrise and sunset. Combine them with other Zigbee devices, for example opening the curtains and switching on the lights when a sensor detects you walking in.



Which motors it suits
The switch works with mains AC motors (100–240V, up to 200W) that have separate open and close wires:
- 4-wire roller shutter and tubular motors with mechanical limits
- 4- or 5-wire sliding curtain motors
Connect live (L), neutral (N) and the motor’s forward (M11) and reverse (M12) wires. The motor’s earth goes to the earth in the wall box. It should be installed by a qualified electrician.
