Tuya ZigBee Wired Gateway Required: This Tuya smart ZigBee IR remote requires a Tuya ZigBee wired gateway for app configuration and smart controls via the Smart Life app. Note: Only a wired hub is compatible with the ZigBee IR remote; wireless hubs are not supported for app configuration. Control via Smartphones: This all-in-one IR remote control can operate household infrared appliances such as air conditioners, fans, set-top boxes, TV boxes, and more using a single SMART IR controller (supports 38KHz IR signals only; RF not included). Add compatible devices to the remote for wireless control via smartphones from anywhere. Control your appliances remotely before arriving home. Voice Control Compatibility: Works with Alexa for hands-free voice control. For example, say “Alexa, set A/C to 77 degrees Fahrenheit” to adjust your air conditioner. Voice commands can activate the SMART IR controller to manage most infrared devices, including air conditioners, fans, TVs, DVD players, set-top boxes, and TV boxes. For a full list of compatible devices, refer to the Smart Life app. Customizable DIY Learning Function: If your IR device brand is not listed in the Smart Life app, use the programmable DIY learning function to copy commands from your existing remote. Most IR remotes are supported, including those for fireplaces, heaters, and ceiling fans. Ensure you have the original infrared remote available for programming. Battery Powered for Flexible Placement: Unlike older WiFi models, this ZigBee version is battery-powered, eliminating the need for a USB cable. Place it conveniently anywhere in the room.
