For those with a sprinkler system on your property, try out the Rachio Smart Sprinkler Controller. It is easy to swap for your old, wasteful system. The Rachio has a waterproof casing, easily connects to your Wi-Fi, and is EPA WaterSense certified. Because of the Wi-Fi connectivity, you can control the device from your phone or computer. What makes Rachio so smart is that it adapts to local weather changes and automatically optimizes your watering schedule. For example: if you water your plants earlier in the morning, you will need less water since cooler temperatures will result in less evaporation. The best part is that it works with any sprinkler system, so you won’t need to replace your entire setup.
