Among the things I've learned. The timers automatically add weather delay based on very loose weather conditions. By default, they will add weather delay on 30% chance of rain and .05 inch of rain. I bumped that way up to 80% and 0.25 inch of rain. Good thing I saw the notification for delay on the app and cancel the delay through the internet.
The last few days of 97-98 deg F and sunny weather forced me to adjust watering cycles. So far so good.
One more thing: I use my big gumbo pot and get the water close to boiling then cut the tightly coiled 1/4" tube to length. Dropping the hose in one at a time and fish it out with tongs. A slight pull through and the hose straightens out nicely. No more fighting with those coils.
