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 All Infrared Appliances via Smartphones: This all-in-one IR remote control activates home infrared appliances such as air conditioners, fans, set-top boxes, and TV boxes using a single SMART IR controller (supports 38KHz IR signals only; RF not included). Add all compatible devices to the remote for wireless control from smartphones. Control your appliances remotely before arriving home. Hands-free Voice Control: Use voice commands with Alexa. For example, say “Alexa, set A/C to 77 degrees Fahrenheit” to activate the SMART IR controller and remotely manage most infrared devices such as air conditioners, fans, TVs, DVDs, set-top boxes, and TV boxes. For full compatibility details, refer to the attached list or the Smart Life app. Customized DIY Copy 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 for fireplaces, heaters, and ceiling fans are compatible. Ensure you have the infrared remote available for the DIY learning process.
