Have you ever seen someone’s irrigation system running during the rain? Maybe they (or you) forgot to turn it off before a storm blew in. Once every now and then it probably won’t matter, over time, the cost could add up. Wi-Fi controllers are a pretty neat tool to help better regulate your lawn and how it gets water. These systems link up through wi-fi to a weather channel outlet. They can tell how much water your area has gotten and will adjust accordingly to get your grass watered efficiently and save you some money. You can also control the system from your phone. Pretty neat!
