Systems and methods for pairing a wireless transceiver unit for sanitary ware are provided. An exemplary pairing method includes emitting a pairing instruction signal from a wireless sender of the wireless transceiver unit, receiving the emitted pairing instruction signal at one or more wireless receivers, and detecting a signal intensity of the pairing instruction signal received at each of the one or more wireless receivers. The method further includes returning a pairing response from each of the one or more wireless receivers to the wireless sender. The pairing response includes an ID of the wireless receiver and an indication of the signal intensity detected at the wireless receiver. The method further includes selecting the pairing response indicating the highest detected signal intensity and storing the ID of the wireless receiver included in the selected pairing response.
