We bought orbit wireless rain sensor.

@Videoguy, great to hear! The wiring for this rain sensor on a Gen1 is below:

The wiring for a wireless rain sensor on a Gen2 is below:

@Videoguy

The orbit receiver has two red wires, one green, yellow and a while wire.

As such, the wiring on a Gen2 for an Orbit wireless rain sensor will be:

S1: Yellow
SC: Red+White
SP: Red

The green wire is NOT needed.

What is right rain sensor setting on the rain sensor? It lets me set from 3mm to 25mm (I.e 1/8" to 1").

This is a personal preference. If you’re in a humid area, I’d recommend you stay above 1/4". Remember, the Rachio allows you to turn on a virtual rain sensor via Weather Intelligence the app.
