The inductor value is chosen based on the maximum current output. The higher the current output the lower the inductance. Although LM2596 is capable of 3A maximum output current, OpenSprinkler is only designed to provide up to 1A, so on the inductor selection graph of the datasheet, we are looking at the upper-left corner of the graph, and that’s 100 to 150uH.
