Have an OpenSprinklerPi (App ver: 1.6.0, Firmware ver: 2.1.7, Hdwe: OSPi-AC) and it watered the lawn this morning even though the outside temp was below 32 degrees F. We now have nicely iced walkways besides the lawns. Any chance of altering the Weather Adjustment to skip with ice would form? thanks for a excellent product.
Have you set your OpenSprinkler to use weather adjustment? It’s not turned on by default. You can go to Edit Options -> Weather and Sensors and select Zimmerman algorithm (for which you will need to provide a Wunderground API key). The algorithms takes temperature into account and I am pretty sure that at 32 degree it should return a 0% water level effectively preventing any program from running.
