To reduce your energy usage with a smart meter, start by monitoring your consumption patterns through the data it provides. Identify peak usage times and try to shift high-energy activities to off-peak periods, if your tariff allows. You can also set energy-saving goals and track your progress over time. Additionally, consider investing in energy-efficient appliances or implementing simple habits like turning off lights when not in use. For more tailored advice, consult your energy retailer or visit energy.gov.au for tools and tips.
