Wasting water is not a wise idea, even if you are doing it to take care of your garden. Smart irrigation controllers such as the Zilker can help you save water by taking into account weather and other factors. This device programs itself and can be controlled from anywhere.
Zilker lets you know when your hose has a leak. It also alerts you if you forgot to turn on the faucet. You will be able to see usage data on your smartphone. With a 915MHz radio, you get a long range. The product is expected to ship next year.
