Rachio 3 and Hunter Wireless Rain Click


Good evening

I just installed my Rachio 3 and the setup was very easy but now I was wondering if anybody got issue to install their rain sensor. I have an Hunter Wireless Rain Click and it seems activated (RED = Wet) and it should be GREEN (Dry)

I turned off the Rain sensor in the rachio app

Thank you !!!


@Galette - From the Hunter manual:

When you first apply power to the receiver,
the SENSOR STATUS LED will be RED. Press
the manual test spindle on the transmitter
for five seconds and release the spindle. The
SENSOR STATUS LED will turn GREEN indicating
proper operation


Yeah…I tried this earlier and still RED. At te same time, I am wondering if it is very necessary to have a rain sensor with Rachio 3.


@Galette - Then I might check the sensor to make sure it is clean, etc.

With a Rachio (Gen 1, 2 or 3) a rain sensor is a “belts and suspenders” approach to catch the situation where there is no precipitation forecast, but it does rain before or during a scheduled run.


@DLane, the rain sensor was green before I replaced my old hunter controller.
Unless 1 wire is not set correctly ?


Ok I switched my 2 yellow wires and press the manual test spindle on the transmitter again and now the rain sensor is GREEN !!!

Thanks @Dlane for your support


@Galette - I’ll have to remember that trick for the next post. Glad you thought of switching the two yellow wires and that it works!
