4. Operation of the Luto Double Curtain Smart Switch

The double curtain smart switch has 4 buttons on its face, corresponding to the buttons: open/stop curtain 1, close/stop curtain 1, open/stop curtain 2, and close/stop curtain 2.

• When the double curtain is open, the indicator light on the Open button will turn red.
• After the double curtain is fully open, the Open button will turn green.
• When closing the double curtain, the indicator light on the Close button will turn red.
• After the double curtain is fully closed, the Close button will turn green.
• When the double curtain is pressed to stop, the Stop button will be similar to the above.

Installing smart switches in curtain systems allows users to operate the system and view its status via an app. This makes it easy and convenient to operate curtains remotely rather than by pulling them manually.

5. Applications of the Luto double Curtain Switch

• Schedule, turn on/off timer: Set a timer for each device and turn it on/off by the hour, day, or week. You may also set up scenes to have the curtain work automatically.

For example: The curtains automatically open at 5:30 a.m. to welcome the new day, and close at 10 p.m. to end the day. Your space becomes significantly more pleasant and convenient.

• With Lumi’s voice recognition solution, you can control the curtain system with your own “powerful voice”.

For example: when you say the command “OK GOOGLE, OPEN CURTAIN; Hey SIRI, OPEN CURTAIN” all the curtains in the house will be completely opened or closed, depending on the command.
