    Why is my Rain Bird SMRT-Y system not watering?

      If your Rain Bird Accessories system isn't watering, ensure your controller is properly set and running. Also, the system will not water if the soil moisture is not below the moisture threshold setting, indicating sufficient moisture level. Take a soil moisture reading to check if it's above the threshold.
