When comparing smart meters, check whether the meter is compatible with your property, solar system and preferred electricity plan, including time-of-use or demand tariffs. Ask the retailer or distributor about installation costs, ownership, data access, communications coverage and what happens if you later switch retailers. Smart meters can provide more frequent usage information, but savings are not automatic and may depend on your tariff and energy habits. Compare the total plan costs and conditions, and check your state or territory energy regulator’s guidance before agreeing to an installation.
