Pairing and DIY copy function Pair the device by searching for it in the app's device library. If the infrared device is not found in the Smart Life app, the programmable DIY learning function can copy the same function from an existing remote control. This makes the C Smart IR Controller compatible with most infrared remote devices. Longrange and full coverage Supports infrared control up to about 15 meters (no obstacles). It provides 720degree allaround signal coverage, allowing effective control within this range. Voice control compatibility Works with voice assistants including Home, Tmall Genie, and Yandex. Use voice commands to activate the C Smart IR Controller and remotely control most infrared devices. Mobile positioning control Enable control of home appliances based on the distance between your mobile phone and the controller. Set the distance in the app from 100 to 1000 meters to turn devices on or off as you approach or leave. Use scenarios Inhome convenience: Use the app or voice control to operate common infrared devices such as televisions, air conditioners, set boxes, and lights without needing multiple remotes. Automated arrival/departure: Set up geofence automation so that when you approach your home within the configured distance, essential devices turn on, and when you leave, they switch off, saving energy. Remote recovery of lost or damaged remotes: If a device is not listed in the app library, use the DIY learning function to copy the original remote's signals, restoring full control without buying a remote.
