Here is my sales pitch:
Hey, I noticed this morning (which I did) that you were watering after it rained yesterday. I used technology last year to reduce my water usage, help save the environment and even more importantly save money! I reduced my watering bill last year by 50% and my lawn still looked great, don't you agree?
I purchased a Rachio Iro smart controller that has a flexible schedule so it's able to water on a different schedule every day based on what is needed! it uses the internet for forecast and then based on the sun, soil and other factors, it adjusts how much water is needed to keep your lawn green without over watering.
Even better, I just installed a Personal weather station which you can also use that allows it become even more accurate based on the micro climate in our neighborhood.
Sounds great? right?
