Yes, I am saying Rachio makes seasonal adjustments. As the heat increases, Rachio changes the watering time, increase with heat and decreases when cooler (winter) season moves in. Prior to getting Rachio I would simply turn off my irrigation system during the winter. Which may not be the best thing do do, depending on whether it’s a wet or dry season. With Rachio, I leave it on and it make the reductions in watering time as the season progresses. Love it!
