I am glad to hear you've installed a weather-based "smart" irrigation controller. The irrigation controller should help you reduce your monthly water use significantly. But, if you are still looking for outdoor tips, I suggest avoiding over fertilizing your lawn, as it can increase your water consumption. Also, aerate your lawn periodically, which allows water to better reach the roots and use a broom or blower to clean leaves from the driveway. All of these tips can help you save water outdoors.
