I created an integration in smartthings IDE with SmartWeather Station Tile, but not load weather (cloud, rain, …), just load in smartthings (humidity, temperature, UV index).
I would like to turn on my irrigation if not rain the last two days.
You could use Webcore to set a date variable when percentPrecip changes to 0% and then count the days from there. Not sure if this will be 100% accurate though as I believe percentPrecip show likelihood of rain as opposed to rain actually falling. Maybe the only way to be 100% sure would be to have a personal weather station.
