Sounds like the noise is probably the bigger nuisance—sensors will misread a quick gust of wind as a rain event, and the controller will keep chasing phantom signals. Control lag is a thing, but if you’re chasing a moving target in the first place, you’ll end up with a watered field that never knows when to stop. Keep the sensor filtering tight, and the lag will look less dramatic.

Glad the plan clicks. Just remember, a Kalman filter will only do its best if you feed it sensible data—no magic dust for gusty wind. And if the PID still feels like a lazy gardener, we’ll get back to the gains. Keep me posted, and good luck proving the wind isn’t actually a secret competitor.

Sounds like a solid plan. Don’t forget to give that derivative a gentle nudge—too much and you’ll just be chasing the wind’s reflection. Ping me when you’ve got the numbers, and we’ll see if the system finally behaves like a polite gardener. Good luck.
