[Multiple Control Methods] After setting the guidance in the Aqara Home app, you will be able to control your curtains when you are away from home, or by voice commands with Siri, Alexa, or Google Assistant. Additionally, the built-in light sensor allows the Curtain Driver E1 to be controlled automatically based on the actual brightness. If it's too bright outside, the curtains will close by themselves.[Smart Home Automations]The Aqara Curtain Motor E1 can help you to enjoy automated control of your existing curtains based on weather, time, lighting conditions or other Aqara devices triggered. You will be able to set a timer to customize a sleep-wake routine that perfectly fits your personal schedule. Automations via HomeKit, Alexa, Google Home and IFTTT are supported.[Powerful Motor]Thanks to its powerful motor, the maximum load of the Curtain Motor E1 can reach up to 26.4 pounds. You can choose between one or two motors per window. In the case of installing two, they will be able to be grouped together so that you can open the curtains simultaneously. Moreover, the speed of the motor can be adjusted to three levels, so it will work more quietly and open the curtain slowly to make waking up more pleasant.[Long Battery Life]A huge 6400 mAh rechargeable battery may last for up to a year without charging. (The calculated battery life refers to opening and closing a curtain on a 5 ft track (i.e., 2 curtain drivers per window) once a day, and it also depends on friction, curtain weight and type.) Moreover, the device can be charged via the Type-C using either a powerbank or a power supply (both not included).
