Q: Does "pairing" require moving the controller close to the device?
A: That depends. Usually, the answer is no; you can pair the device from anywhere within its operating range (approximately 25 to 100 feet, depending on obstructions).
However, some devices, including many door locks, require bringing the controller very close to the device, within a 3-foot (1-meter) range. This requirement is for extra security, and after the device is paired, it will work with a normal range. All Vera controllers offer a battery power option to accommodate this occasional requirement.
