Aqara Curtain Driver E1 - Rod Version

Up to 1-Year Battery Life*: Energy-saving technologies and a huge 6000 mAh battery make the Curtain Driver E1 apparently the most long-lasting controller of its type. You can forget about charging it for up to a year. Zigbee 3.0 Protocol: Enjoy the benefits of the fastest, most stable, and energy-efficient smart home technology. Better stability and compatibility (more standardized protocol), longer support, and more features. Built-in Light Sensor: 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 open by themselves and vice versa!. Easy Installation: The installation is very fast and does not require any additional tools: the Curtain Driver can simply be mounted onto the existing curtain rails.
