Review: Really works! - These things really work. Don't be "that guy" whose sprinklers are on when it's raining...
Review: Connecting to older Rainbird controller - If installing on older model Rainbird controller, disconnect the TWO common wires (mine were white) from unit's zone(s) solenoid AND the motor switch and connect BOTH to the RSD. The RSD is nothing more than an ON/OFF switch. The instructions with the device makes it appear that you should only connect the common wire from the zone(s) solenoid. If you did this, what would happen when it rains enough for the RSD to work would be the zone(s) solenoid would shut off but your pump motor would still operate. The motor would probably burn out.

## Features

- Rainfall detection using hydroscopic discs.

### ⭐⭐⭐⭐⭐ Really works!

### ⭐⭐⭐⭐⭐ Much needed automation
*by S***. on December 22, 2020*

Purchased this for my parents to add to their Rain Bird sprinkler system. Because their unit is placed clear across the backyard, it meant they had to go out into the rain to turn off the auto-sprinkler system. It was super easy to install and has already eliminated cross-yard walks in the rain!
