FIG. 1 is a first embodiment of a wireless rain sensor with a graphical user interface, where the graphical user interface of this embodiment indicates that irrigation is allowed; and,

FIG. 2 is a second embodiment thereof, where the graphical user interface of this embodiment indicates there is a rain sensor override and irrigation is allowed.

The broken lines showings of the values of the battery indicator, the signal strength indicator, the pairing indicator, the temperature threshold indicator, the temperature indicator, the rainfall threshold indicator, the rainfall indicator, the rain trip indicator, the freeze indicator, and the suspend irrigation indicator in FIGS. 1 and 2, and the irrigation override indicator in FIG. 1 are included for the purpose of illustrating unclaimed portions of the wireless rain sensor with graphical user interface and form no part of the claimed design. The perimeters of the portion of the underlying wireless rain sensor and the graphical user interface are understood to be flush.
