Which one should you buy?

For most Australian homes with ducted reverse-cycle or gas heating, the Google Nest Thermostat is the top pick: it is the cheapest mainstream learning thermostat, looks the part, and pairs cleanly with Google Home. The Meross MTS200 is the value pick for hydronic, gas-boiler and electric underfloor setups, with a huge review base and HomeKit support for well under $120. The Inkbird ITC-308 WiFi is the budget winner, because it plugs straight into a power point and controls any portable heater or cooler without touching your wiring.

For full context on why we ranked these the way we did, what alternatives we considered (and rejected), and the broader buying-guide framework, read the full The Best Smart Thermostats in Australia (2026): Tested Picks for Ducted, Split-System and Hydronic Homes.
