Infrared control: air conditioners, TVs, and fans. A built-in code library supports signal pairing and control for three infrared devices: TVs, set-top boxes, and air conditioners. It supports ZigBee temperature control panels, Zhonghong ZigBee wired remotes, and Demrui ZigBee wired remotes, and includes five high-power infrared emitters. A built-in human presence sensor automatically wakes the screen when someone approaches a certain distance from the panel. The sensor setting allows you to customize the distance, offering a more detailed experience. Multiple voice wake-up words are available to prevent multiple devices from responding simultaneously when you call "Xiaozhi Butler." Commands and linkages can be executed within a specific area based on zone names, such as "Living Room Butler" and "Room Butler." Weather, time, temperature, and humidity are all controlled on one screen, allowing you to stay informed of every subtle change in your world. Compatibility: Fully compatible with Tuya-Zigbee ecosystems, making it easy to integrate with your existing smart home setup. The four-inch screen offers a clear and intuitive interface, making device management straightforward and hassle-free.
