It does though up to a point.
See when you initially calibrate the carrots (sensors), one is matching it to the current soil moisture level so if its too wet for the plant, it needs to be adjusted as the sensor will keep it at that moisture level and could destroy the roots, allow the soil to go anaerobic etc.adding more water through drenches messes with the calibration and the roots freak out not getting enough air if they decide to not uptake the water. Later on, when the plant wants more water, it needs to be adjusted again otherwise they freak out as the soil goes too dry for them...., you must work with the sensor(s) to maintain a moist and not wet or water logged soil.
Another hoop to jump with them is if the water line isn't a closed loop, air can get in the line which can throw the sensor(s) off leading to under or over saturation, flood etc....same if the water reservoir is not filled before its empty as the carrot will drain if the line/reservoir isn't filled in time or if the sensor gets placed in a dry pocket or if a water line gets clogged from sediment from the reservoir etc.
A bit later today, i'll do a write up of them in the DBHP thread as I am transplanting them and adding 3 more carrots to the existing line
