This significantly reduces the effective range. Do not mount near electrical wires, transmitting antennas or other items that will interfere with the signal. Any obstacles, such as walls, windows, stucco, concrete or large metal objects can reduce the range of the signal. Position the display inside the house away from electrical devices such as computers, TVs or routers, as these can interfere with the signal. Sensors should be mounted vertically to allow condensation to drain. For best transmission, sensors should be mounted at least 6 feet above the surface.
