Review: Great product - Fantastic product, it shuts the system down when it rains saving water and energy. easy to install and connects to Wi-Fi flawlessly.
Review: Sensor works well. I installed on a Hunter Pro-C controller - I have had this sensor installed for the past month and it works fine. I don't have the temp feature with mine. The install took only a few minutes. I installed the LCD to the right of my timer so I could flip up the cover to read the screen. The wireless WR2 sensor is mounted on a wooden fence about 15' away. The signal goes through a garage wall that is made with 2x6's and has sheet rock and plaster on the inside. The signal strength on the LCD shows 3 out of 4. The battery strength is also read on the LCD and is still 4 out of 4 after 30 days use. The LCD also shows when the system is shut off. There will be a pic of a rain cloud and an X through the sprinkler on the LCD. When the Rainbird sensor shuts off the controller the controller should also say OFF if you have the sensor switch on the controller in the active or ON position. One word of advice is.... If installing with a Hunter Pro-C controller, and possibly other Hunter controllers, make sure you remove the jumper plate that connects the 2 sensor inputs on the controller. You have to take both sensor screws out and the plate pops off. Then just connect the white and green sensor wires from the Rainbird. I would recommend this product to a friend. Follow up: I have had this sensor now for a full season and it has paid for itself with the savings in water. It still works as well as when I first installed the unit 02/15 Follow up: Still works fine. I do change the battery in the sensor every year.

## Questions & Answers

**Q: I have an esp13 rainbird controller is this rain senor conpatible?**
A: I use my WR2 Rainbird rain and freeze sensor on a Rainbird SST-600i controller and it works great - have saved a lot on the water bill this year with all the rainy days, but have also kept the yard watered on the dry hot days without having to touch the controllers.  As for using the WR2 Rainbird rain and freeze sensor on the ESP 13 controller, I do not have first hand experience with this, but in reviewing the manuals for the ESP 13 controller and WR2 Rainbird rain and freeze sensor, the manuals indicate it is recommended for those controllers and the manuals provide connection instructions.  The manuals can be reviewed at the following websites: http://www.rainbird.com/documents/turf/ts_ESPModular.pdfhttp://www.rainbird.com/documents/turf/man_ESP-LXME_InstallationTroubleshootingGuide.pdfhttp://www.rainbird.com/documents/turf/man_WR2.pdf

**Q: Are there replament discs since wr2 disk assembly - #637810s is no longer available  even though the manufacture still sells this rain sensor (??!!)**
A: Go to ebay and search Hygroscopic Disks and you'll find plenty of just the Discs.  You can get a pack of 5-10 for $5 and they'll make your sensor work as new.

**Q: Mine is sst-600in, does it work with this model? i can directly connect the sensor to it or i need to buy a transformer?**
A: I spliced the sensor power wires into the wires running from the transformer powering the controller.  Works fine, no additional transformer needed.

**Q: What is the difference between the 553000 & 553100?**
A: The A553000 was the old version WR2RC which was a rain sensor only.  The A553100 is the new WR2RFC rain & freeze sensor.  Rain Bird only sells the newer A553100 now.

### ⭐⭐⭐⭐ Overall a good product!
*by E***N on August 14, 2016*

Purchased this item several months ago to attach to a Rachio Sprinkler system. The instructions were clear and easy to attach to the sprinkler system. The unit is roughly 25 feet from the device that connects to the sprinkler controller and we've never seen any sort of connectivity issues. It's setup is basic, but it's very straight forward and easy to use. There has been several storms with hail large enough that we've had to replace our shingles, however the wireless sensor has remained undamaged. This may be slightly due to luck that a large piece of hail didn't hit the wireless sensor, but it has held up well considering the drastic changes in weather we get here in Nebraska. Over all, it does seem to be quite durable. We will see how it holds up during the winter. I'm giving it 4 stars since the connector for our gutter system was a bit tricky to get on and we had to bend a small metal lip on the edge of the gutter to secure it. It seemed like the plastic piece that hooks to the gutter was almost about to break before we were finally able to hook it on. Over all a good product, and I would recommend it as a good addition to any sprinkler system that can accommodate a rain sensor.
