1. A method for pairing a first wireless device with a second wireless device, the method comprising:
determining, by a wireless transceiver of the second wireless device, a first value of signal strength of a wireless signal of the first wireless device transmitted from a first location of the first wireless device, the first location of the first wireless device being proximate to a second location of the second wireless device;
causing, by a processor of the second wireless device, one or more visual cues to be output on a graphical user interface of the second wireless device, the one or more visual cues including instructions for a user to physically move the first wireless device in at least one direction to arrive at a third location, the third location being proximate to one or more of (i) the second location or (ii) a fourth location of a third wireless device;
determining, by the wireless transceiver of the second wireless device and based at least in part on monitoring the wireless signal of the first wireless device, a second value of signal strength of the wireless signal of the first wireless device transmitted from the third location of the first wireless device;
determining, by the processor of the second wireless device, a variation in signal strength between the first value and the second value;
identifying, by the processor of the second wireless device, the first wireless device for pairing with the second wireless device based on determining that the variation in signal strength from the first value of signal strength to the second value of signal strength indicates the first wireless device has moved in the at least one direction indicated by the instructions in the one or more visual cues; and
establishing, by the processor of the second wireless device, a wireless communication channel between the first wireless device and the second wireless device.
