The Tailwind iQ3 system is comprised of a sensor that you put on your garage door and a module that attaches to your garage door opener. The package comes with all the hardware you need to get up and running, including a wire that connects the sensor to the control module and clips and tape to secure the module and wire. You can control up to three garage doors with the module, though each door needs a sensor installed.
Android users who have a car with Bluetooth can use the auto open/close feature without any additional hardware, but iPhone users will need a separate sensor — a small white disc — to put in the car to make that feature work.
