Weathermatic SLW1 Economy Wired On-Site Rain/Freeze Weather Sensor

The SLW1 weather station provides rain and freeze sensing to prevent watering during periods of rain and freezing weather. The rain override will stop watering after the selected amount of rain is received (factory setting is 1/8 inch). Available settings are 1/8 inch to 3/4 inch (3 to 19 mm) Using the lock tab, select the desired setting. The SLW1 weather station freeze sensing function will prevent watering when the outside temperature drops below 37 degrees Fahrenheit (1.5 degrees Celsius). Watering can resume when the temperature increases above 37 degrees F (1.5 degrees Celsius). The SLW1 weather station is designed for years of maintenance-free operation. The SLW1 does not utilize any onboard power source. Operational power is provided from the controller. To be used with Weathermatic SmartLine Controllers. Maximum controller to weather station distance is 200 feet. For installations requiring greater distance, use the SLW15 or SLW10 weather stations.

works well, but limited reliability
I have installed many of these over the past 8-10 years. They seem to have a life span of 4-6 years and occasionally have failed right out of the box.

When they are working, I love the Weathermatic Smart Adjust system, but the weather monitor does seem to be the weakest part of the set up.

Haven't had any rain yet, so not sure if it works. Controller senses it.

Does the SLW1 sensor come with the SLHUB1 receiver hub?
Robert M on Jul 10, 2019
BEST ANSWER: The SLW1 is a wired sensor and does not require a receiver. You just directly connect the SLW1 to the controller using the provided wire.
I have an older model Weathermatic control box - Weathermate-model# WM-9 A020101792

is this sensor compatible ?

Thanks
Vinny L on May 25, 2013
BEST ANSWER: No, this sensor is only for the Smartline series controllers.

For the Weathermate you want just a regular rain sensor.
Will the SLW1 weather station work with all SL1600 controllers or do they only work with new controllers?
Bill M on Oct 11, 2012
BEST ANSWER: It does work with the smart line 1600.
