No wire installation is required among units. The WMR112/112U has an effective range of 100 meters in an open area. Position the units within the range and be sure the transmission path is clear of interference and obstacles. Note: The anemometer, thermo-hygrometer and rain gauge should be installed outdoors and in locations that best measure the weather elements which the instruments are designed for. As for the barothermo-hygrometer, it must be installed indoors. If you have any optional thermo or thermo-hygro sensors, they can be installed outdoors or indoors.
