The Zimmerman weather algorithm already accounts for freezing condition — when temperature is very low, the algorithm will output a water level of 0%, preventing watering.

If you want to use a sensor instead, you can get a rain sensor, connect to OpenSprinkler’s sensor terminal, and enable Rain Sensor in settings.. Many rain sensors also account for freezing condition (they are often called rain and freeze sensors). So this should fit your need.

We are currently away till Monday July 21. Orders placed during this time will be shipped on Tuesday July 22. Thank you for your understanding!
