Which one should you buy?

No single thermostat suits every Australian home, because the right one depends on your heating system. On 16 October 2026, four of the seven we reviewed were Global Store imports and two were unavailable. The Inkbird ITC-308 WiFi, rated 4.6 from 161 ratings, ships from Amazon and controls plug in heaters and coolers. The Meross MTS200 is listed for boilers and water based underfloor heating, shows 4.4 stars from 2,729 ratings, and was a Global Store import from Germany on 16 October 2026.

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 Best Smart Thermostats in Australia (2026): What Works for Ducted, Split System and Hydronic Homes.
