I have a suggestion.
I used to think that midday watering on a very hot and sunny day was bad for the lawn, but I recently learned that was a myth. I’ve been reading and it is actually beneficial to do some light midday watering on hot days to cool off the the soil and reduce the effects of heat stress in the lawn.
I’m going to keep my primary watering early in the morning, but it would be nice to have a second midday schedule that starts only if the temperature is above 85 degrees, and runs for just a few minutes. I can set a schedule to do this everyday, but on cooler days, it would be a waste of water.
The simpler way of accomplishing this would be adding a “Only water if the temperature is above X degrees” feature to a specific water schedule.
But heat stress comes into play when multiple hot days in a row strike with no cooler recovery period. A smarter way of implementing this would be “Only water if the temperature average for the past 3 days is above X degrees.” Thanks!
