Designed for the smart home enthusiast who wants to control their environment with a simple press, the FlexFob is perfect for setting up custom actions like turning off all lights at bedtime or triggering a morning routine. This device moves beyond basic home security by offering a tangible way to simplify daily tasks and enhance convenience.
Each of the four buttons can be programmed with two functions, allowing you to activate Alexa routines or IFTTT applets seamlessly. The LoRa-powered technology ensures reliable performance with over a quarter-mile range, so you can use it from anywhere in your home without worrying about connectivity. With up to five years of battery life, it integrates smoothly into your setup, though a YoLink Hub is required for full functionality to unlock all features like controlling sirens, locks, and lights.
