Which smart thermostat is worth buying in Australia?
The best smart thermostat in Australia depends on your heating system. On 16 October 2026 none of the five wall thermostats we reviewed on Amazon AU was both in stock and sold from Australia, and tado's radiator valve set was a UK import. The Inkbird ITC-308 WiFi, a plug in controller for heaters and coolers, shipped from Amazon.
Compatibility comes first: a smart thermostat only works if your heating and cooling system has somewhere to connect it. Search assistant answers we saved for this guide warn that many Australian inverter and ducted systems use proprietary controls rather than standard 24 volt thermostat wiring, so conventional US market thermostats may not work without a compatible interface. Wall mounted split systems that use an infrared remote need a different kind of device again. That is why this guide is organised by the system you have rather than by brand.
We read the Amazon Australia listing for each product card below and recorded its star rating, rating count, seller and stock status. We did not test the thermostats ourselves and we did not read owner review text, so the facts here come from the listing text or from the search answers we saved. Check your own wiring and system before you buy.
Which smart thermostat suits your heating system?
Start with the system you already have, because that decides what will work. Ducted reverse cycle and gas central systems, wall mounted split systems with an infrared remote, hydronic or underfloor heating and plug in heaters each need a different type of device. Then check wiring, the smart home apps you use, and who installs it.
| Your heating or cooling system | What it usually needs | On this page |
|---|
| Wall mounted split system with an infrared remote | A smart air conditioner controller that learns the remote's signals. A wall thermostat cannot control it. | No product card. A search assistant answer we saved names Sensibo Sky for this case, and the Sensibo Air listing says it works with virtually all air conditioners and heat pumps that use an infrared remote. |
| Ducted reverse cycle with a proprietary controller | A controller matched to the ducted system, because many Australian inverter and ducted systems use proprietary controls rather than standard 24 volt thermostat wiring. | No product card. A search assistant answer we saved names AirTouch 5 for ducted systems with multiple zones, Daikin Airbase for compatible Daikin ducted units and Milieu Climate for Australian focused controls. |
| Conventional central heating with compatible wiring | A wall thermostat that matches the wiring, and on some systems a C wire or other compatible power accessory. | Google Nest Thermostat, Google Nest Learning Thermostat (3rd Gen) and ecobee Smart Thermostat Essential. The Google Nest Thermostat and the ecobee Essential could not be bought on 16 October 2026. The Nest Learning Thermostat was an Amazon US Global Store import on 16 October 2026. |
| Boiler, hydronic or water based underfloor heating | A wall thermostat or receiver box made for boilers or underfloor heating. The Meross MTS200 listing says it is compatible with most boilers and water based underfloor heating. | Meross MTS200 and Honeywell Home T6, both Amazon Germany Global Store imports on 16 October 2026 |
| Radiators with thermostatic valve heads | Smart valve heads that replace the existing heads. The tado listing says they only work with a separately sold tado Starter Kit. | tado Smart Radiator Thermostat 3 Pack, an Amazon UK Global Store import on 16 October 2026 |
| Plug in heater or cooler | A plug in temperature controller, used within its rated load. | Inkbird ITC-308 WiFi |
What is a smart thermostat?
A thermostat is an electronic or mechanical control device that regulates temperature by turning heating or cooling systems on or off to maintain a target setpoint. A smart thermostat adds WiFi so you can control it from an app. Common types are mechanical, digital, programmable and smart WiFi.
A smart thermostat needs a steady WiFi signal, so see our WiFi router buying guide for a smart thermostat.
- Mechanical: uses physical movement, such as a bimetallic strip, and is durable but less precise.
- Digital: uses electronic sensors and microcontrollers for accurate, stable temperature readings.
- Programmable: lets you set time based schedules that lower or raise the temperature when you are away or sleeping.
- Smart WiFi: connects to the internet for app control, remote geofencing, energy tracking and smart home integration.
Source: the Google AI Overview for the search thermostats, saved on 16 October 2026. A plug in unit that switches a heater or cooler is a temperature controller rather than a wall thermostat, and the Inkbird ITC-308 WiFi below is one.

Which thermostats could you buy from Amazon AU on 16 October 2026?
On 16 October 2026 we looked at seven thermostat products on Amazon AU: the Inkbird ITC-308 WiFi shipped from Amazon and was sold by inkbirdau, four were Global Store imports from Germany, the UK or the US, and two showed Currently unavailable.
- Meross MTS200: on 16 October 2026 the listing showed Amazon Germany as the seller through the Global Store, with a notice that imports from Germany may differ from local products.
- Google Nest Thermostat: could not be bought on 16 October 2026, because Amazon AU showed Currently unavailable and said it did not know when or if the item would be back in stock.
- Inkbird ITC-308 WiFi: the listing shows it ships from Amazon and is sold by inkbirdau, with no import notice.
- Google Nest Learning Thermostat (3rd Gen): on 16 October 2026 the listing showed Amazon US as the seller through the Global Store, with a notice that US imports may differ from local products and a low stock warning.
- ecobee Smart Thermostat Essential: could not be bought on 16 October 2026, because Amazon AU showed Currently unavailable and said it did not know when or if the item would be back in stock.
- Honeywell Home T6: on 16 October 2026 the listing showed Amazon Germany as the seller through the Global Store, with dispatch usually within 3 to 4 weeks.
- tado Smart Radiator Thermostat 3 Pack: on 16 October 2026 the listing showed Amazon UK as the seller through the Global Store, with a notice that UK imports may differ from local products.
Before you order any thermostat, work through this short checklist.
- Name your heating or cooling system and find its row in the table above.
- Photograph the wiring behind your current thermostat and look for a C wire or power accessory note in the listing.
- For an import, read Amazon's notice on the listing and ask the seller about voltage, plug type and warranty.
- Have an electrician or HVAC technician verify wiring and compatibility before installation, and check voltage, wiring and system compatibility first.
How did we choose these smart thermostats?
We are a small Australian team, not a lab, and we are upfront about that. We do not pull thermostats off a wall and wire them into a test rig. Instead we aggregate the evidence that already exists and filter it through one question: will this actually work in an Australian home? Here is the method we followed.
Last checked: 16 October 2026. Ratings, counts, sellers and stock on this page come from the Amazon AU listings.
- Amazon Australia listings first. Each product was checked against its Amazon Australia listing, including the maker's bullets and product information table, for its star rating, rating count, seller and stock status, and imports are flagged in the product sections.
- System compatibility, not brand hype. We sorted the products by the heating and cooling system Australians may own: ducted reverse cycle, gas central, split system, hydronic and underfloor, radiators and plug in heaters. A thermostat that cannot connect to your system is no use to you, however well it is rated.
- Listing facts, not owner reviews. We used the listing text and the rating figures. We did not read owner review text, so we do not repeat what owners say about wiring, setup or support.
- Ratings and review depth. We favour units with a solid star rating backed by enough reviews to be meaningful, rather than a perfect score from a handful of buyers.
- Who installs it. Plug in controllers need no wiring. Wall thermostats connect to your heating system's wiring, so have an electrician or HVAC technician verify the wiring and compatibility before installation, as the search answers we saved advise.
Where a product that dominates overseas reviews is not genuinely available or suitable here, we say so plainly rather than pad the list. That is the whole reason NestPath exists.
Meross MTS200: a wall thermostat for boilers and underfloor heating
The Meross MTS200 is a wall thermostat that its listing says is compatible with most boilers and water based underfloor heating, with no hub needed. The Amazon AU listing shows 4.4 stars from 2,729 ratings. At the 16 October 2026 check it was sold by Amazon Germany through the Amazon Global Store, and Amazon's notice says imports from Germany may differ from local products.
The listing describes a unit measuring 8.6 x 8.6 x 4.2 cm with a pure white LED backlight under a glass pane. It needs no hub and requires a 2.4 GHz WiFi network. It supports voice control from Siri, Alexa and Google, and device control through the Meross app and Apple Home. It has a double sensor system, an integrated sensor for air temperature and an external sensor for overheating protection of the floor, and the listing states 0.1 degrees Celsius temperature accuracy with an adjustable range of 5 to 35 degrees Celsius.
The listing also describes a summer mode designed for cooling systems such as air energy heat pump systems, and says Meross offers two years warranty and lifetime technical support. The package holds one thermostat, one sensor, four screws and installation instructions, and the listing says English language is not guaranteed for those instructions. For a home with boiler or water based underfloor heating that wants app control, it is worth checking against your exact system.
Flaws but not dealbreakers
The listing does not state a power supply or voltage, so have an electrician or HVAC technician verify the wiring and compatibility before installation. The listing says the installation instructions may not be in English. You set the schedule yourself: the listing describes control by app, voice command or automatically according to time windows and scenarios. Amazon's notice on the listing says imports from Germany may differ from local products, so confirm the voltage and warranty terms with the seller before you order.
Google Nest Thermostat: for compatible central heating wiring
Could not be bought on 16 October 2026: Amazon AU showed Currently unavailable and did not know when or if the Google Nest Thermostat would return. The listing describes an ENERGY STAR certified smart thermostat for home, rated 4.1 stars from 16,787 ratings. We keep the section so you can compare it with the units that were available.
The listing states ENERGY STAR certification. It says the thermostat turns itself down when you leave so you do not waste energy heating or cooling an empty home, and that you can program an energy efficient schedule in the Google Home app. Remote control lets family members change the temperature from anywhere on a phone, laptop or tablet. Savings Finder suggests tweaks to your schedule, and HVAC monitoring sends an alert if something does not seem right with your system. The controls listed are button control, Google Assistant and Amazon Alexa.
For an Australian buyer the main question is wiring. A search assistant answer we saved warns that many Australian inverter and ducted systems use proprietary controls rather than standard 24 volt thermostat wiring. The listing shows 4.1 stars from 16,787 ratings.
Flaws but not dealbreakers
The big one is the C wire question. The listing says the Nest Thermostat is designed to work without a C wire in most homes, but for some systems, including heating only, cooling only, zone controlled and heat pump systems, you need a C wire or other compatible power accessory. Before you buy, photograph the wires behind your existing thermostat and check compatibility. Remote control from a phone also needs an internet connection.
Inkbird ITC-308 WiFi: a plug in controller for heaters and coolers
The Inkbird ITC-308 WiFi is a plug in temperature controller, not a wall thermostat: you plug it into a power point and plug a heater or cooler into it, so it needs no wiring to your heating system. The Amazon AU listing shows 4.6 stars from 161 ratings, and the listing shows it ships from Amazon and is sold by inkbirdau.
This type of controller suits anyone with a portable electric heater or an oil column heater rather than a wired heating system. For cooling, see our guide to evaporative coolers. The listing says the dual relay output can connect a heating and a cooling device at the same time. The free InkbirdSmart app supports iOS and Android over a 2.4GHz WiFi router, and the listing includes a high and low temperature limit alarm and temperature calibration. The listing states a maximum output load of 2200 watts at 220V and 2400 watts at 240V, so check your heater's wattage against that.
The listing table shows 220 Volts, a corded electric controller, and control by app, remote and voice. The plug type is not stated, so check the plug and your heater's wattage before buying. Because it plugs in, there is nothing to rewire, and you can take it with you when you move.
Flaws but not dealbreakers
It is not a wall thermostat for your central system, so it will not control ducted heating or a split system air conditioner. It controls whatever you plug into it, within its load rating. The listing gives the controller 2 years warranty and the temperature sensor 1 year warranty. If you want a single wall unit wired into your heating, look at the wall thermostats on this page; if you want flexible control of a plug in heater or cooler, this is the type to consider.
Google Nest Learning Thermostat (3rd Gen): a learning wall thermostat
The Google Nest Learning Thermostat (3rd Gen) is a programmable smart thermostat that, according to its listing, learns your schedule and the temperatures you like and programs itself. The Amazon AU listing shows 4.3 stars from 603 ratings. At the 16 October 2026 check it was sold and shipped by Amazon US through the Amazon Global Store, with a low stock warning of only 5 left, and Amazon's notice says US imports may differ from local products.
The listing says Home/Away Assist automatically adjusts the thermostat to an Eco Temperature after you leave, so you do not heat or cool an empty home. Energy History on your phone shows how much energy you used and why, and the Nest Leaf appears when you choose a temperature that saves energy. It works with the Nest Temperature Sensor, sold separately, so a certain room can be the one that matters. The design uses polished metal finishes and a bright, high resolution display, and Farsight shows the temperature, weather or time when you walk in the room. The listing table names Alexa and Google Assistant for voice control.
The listing says it is easy to install, typically in 30 minutes or less, with everything you need included in the box, and compatible with 95% of heating and cooling systems. Treat the compatibility figure as a listing claim and check your own system.
Flaws but not dealbreakers
The listing table shows a 24 Volt supply and a corded electric power source, so the same compatibility homework applies. A search assistant answer we saved says imported Nest models are not universal replacements for Australian thermostats, especially on proprietary ducted systems, and to check voltage, wiring and system compatibility first. Amazon's notice on this listing says US imports may differ from local products.
ecobee Smart Thermostat Essential: energy reporting in its app
Could not be bought on 16 October 2026: Amazon AU showed Currently unavailable and did not know when or if the ecobee Smart Thermostat Essential would return. The listing describes the 2025 model, ENERGY STAR certified, rated 4.3 stars from 1,848 ratings, with a colour touchscreen. We keep the section for reference.
The listing claims savings of up to 23 percent every year on heating and cooling costs and says the cost of the thermostat is covered in just six months, which are maker claims rather than guarantees. It says the thermostat is compatible with up to 95 percent of systems and points to an online ecobee Compatibility Checker. It automatically adjusts to your set schedule to save energy when you are gone, tracks energy consumption in the ecobee app, and works with Siri, Alexa and Google Assistant. For homes without a C wire the listing offers the ecobee Power Extender Kit, sold separately.
If it returns to stock, the questions to ask are the same as for any wall thermostat: does your system have the wiring it needs, and does the compatibility checker named in the listing accept your setup?
Flaws but not dealbreakers
The title states that the Essential supports only 1 fan speed, which matters for some multi speed systems. The listing says the Power Extender Kit and the trim kit are both sold separately. Check system compatibility carefully for an Australian setup.
Honeywell Home T6: HomeKit and geofencing for boiler homes
The Honeywell Home T6 is a WiFi and app enabled thermostat that, according to its listing, works with Apple HomeKit, Google Home, Alexa and IFTTT. The Amazon AU listing shows 4.4 stars from 117 ratings. At the 16 October 2026 check it was sold by Amazon Germany through the Amazon Global Store, with dispatch usually within 3 to 4 weeks, and Amazon's notice says imports from Germany may differ from local products.
The listing describes geofencing that uses your smartphone location to determine when you are home or away, saving energy and ensuring comfortable temperatures when you return. It offers 7 day, 5/2 day and single day scheduling with up to 6 different time settings per day, which you can adjust remotely if plans change. The thermostat attaches to a wall plate, and the listing also includes a receiver box with an LED indicator and a button for manual start of the boiler.
For an Apple household the draw is HomeKit support combined with location based automation. The listing does not say which Australian heating systems it suits, so confirm with an electrician or HVAC technician that the receiver box matches your boiler or heating controls.
Flaws but not dealbreakers
The receiver box design is aimed at boiler style heating, so it is less relevant if you have ducted reverse cycle air conditioning. The two part install, a wall plate unit plus a receiver box, is more involved than a single wall unit. The T6 rewards a buyer who matches it to the right system and has the wiring confirmed by an electrician.
tado Smart Radiator Thermostat 3 Pack: room by room radiator control
The tado Smart Radiator Thermostat 3 Pack is an add on for radiators, not a wall thermostat. The Amazon AU listing shows 4.5 stars from 2,730 ratings. At the 16 October 2026 check it was sold by Amazon UK through the Amazon Global Store, and Amazon's notice says UK imports may differ from local products.
The listing says the smart radiator thermostats replace your existing thermostatic radiator valve heads and fit almost any valve directly or with an adapter, mounted vertically or horizontally. You can control multiple radiators room by room and set heating schedules based on your routine from the app. The set comes with 3 smart radiator thermostats, adapters and batteries. Listed features include weather adaptation, statistics, an energy savings report, a heating boost function, and frost and child protection, and it works with Alexa, Apple HomeKit and Google Assistant.
It is aimed at a home with radiators that have replaceable valve heads and that wants different temperatures in different rooms rather than one set point for the whole house. Check the listing's adapter note against your own radiator valves before you order.
Flaws but not dealbreakers
The crucial caveat: this 3 pack is an add on. The listing says it only works with a tado Starter Kit (V2, V3 or V3+), available separately, so budget for that on top or you will have three valve heads that cannot connect to anything. It is also only relevant if your heating runs through radiators with replaceable valve heads. For homes that fit that profile it is a specialist option; for everyone else it is the wrong tool.
What should you look for in a smart thermostat in Australia?
Start by checking compatibility with the system you already own, because that determines whether any of this works at all. A wall thermostat needs compatible wiring, a split system with an infrared remote needs an air conditioner controller, and a plug in heater needs a plug in controller. Then weigh wiring, your smart home ecosystem and who installs it.
What heating and cooling system do you have?
This decides everything. A wall thermostat cannot control a wall mounted split system that uses an infrared remote, and ducted systems may use proprietary controls rather than standard 24 volt wiring. Boiler and water based underfloor heating, radiators and plug in heaters each suit a different device, as the table above shows. Match the type to the system first.
Does your wiring have a C wire?
A common wire, or C wire, delivers continuous power to a smart thermostat. The Nest Thermostat listing, saved on 16 October 2026, says it is designed to work without one in most homes, but some systems need a C wire or other compatible power accessory. Photograph your wiring and have an electrician or HVAC technician verify compatibility before you buy.
Which smart home ecosystem do you use?
If you are an Apple household, look for HomeKit support: the Meross MTS200, Honeywell Home T6 and tado listings name Apple HomeKit, and the ecobee Essential listing names Siri. The Nest Learning Thermostat title says compatible with Alexa, and its listing table names Google Assistant. Pick the unit that speaks your setup's language.
WiFi thermostat or true smart thermostat?
A WiFi thermostat lets you change settings from an app. A smart thermostat goes further. The Nest Learning Thermostat listing says it learns your schedule and the temperatures you like and programs itself, and the Honeywell Home T6 listing describes geofencing that uses your phone location to detect when you are home or away.
Will you install it yourself?
The Inkbird listing describes the controller as plug n play and easy to use. Wall thermostats connect to your heating system's wiring: the Nest Learning listing says typically 30 minutes or less to install, and the ecobee listing says easy DIY install. Have an electrician or HVAC technician verify wiring and compatibility before installation.
How do you keep a smart thermostat running well?
Keep it on a stable 2.4GHz WiFi network, calibrate the reading if it sits in a draught, use an external sensor where the listing includes one, let app updates install, and set a schedule you then leave alone. The Meross and Inkbird listings require 2.4GHz WiFi, and the Inkbird listing supports temperature calibration.
- Keep it on stable WiFi. Smart features depend on a connection. The Meross and Inkbird listings say a 2.4GHz WiFi network is required, so make sure your router covers the wall the device lives on. A mesh node nearby can help in larger homes.
- Calibrate the temperature if it reads off. The Inkbird listing says it supports temperature calibration, so you can offset the reading against a separate thermometer. If a thermostat sits near a sunny window or a draught, a small calibration keeps it honest.
- Use the external probe where one is included. The Meross listing includes an external sensor for overheating protection of the floor, and the Inkbird listing gives its temperature sensor 1 year warranty. For underfloor or awkward locations, an external probe measures where it is placed rather than where the unit hangs.
- Keep the app and software updated. Let updates install so you get the latest fixes and features. The ecobee listing mentions free software upgrades.
- Check batteries before the heating season. The tado listing says its set comes with batteries, so freshen them before the heating season so the valve heads do not drop offline on a cold night.
- Set a sensible schedule, then leave it. The savings come from the schedule and the away mode doing their job. Constant manual overrides undo the benefit, so dial in a routine and trust it.
Frequently asked questions about smart thermostats in Australia
What is the best smart thermostat in Australia?
It depends on your heating system, so we could not name one best buy. On 16 October 2026 four of our seven products were Global Store imports and two showed Currently unavailable. The Inkbird ITC-308 WiFi, which ships from Amazon and controls plug in heaters, was the one product without either problem.
Do smart thermostats work with split system air conditioners in Australia?
Not directly. A wall thermostat cannot control a split system air conditioner that uses an infrared remote. The Sensibo Air listing says it works with virtually all air conditioners and heat pumps that use an infrared remote, and the listing shows it shipped by Amazon and sold by Sensibo, Inc.
What is a C wire and do I need one?
A C wire, or common wire, supplies continuous power to a smart thermostat. The Google Nest Thermostat listing (a unit that could not be bought on 16 October 2026) says it is designed to work without one in most homes, but heating only, cooling only, zone controlled and heat pump systems need a C wire or other compatible power accessory.
What is the difference between a WiFi thermostat and a smart thermostat?
A WiFi thermostat lets you change settings from an app. A smart thermostat goes further. The Nest Learning Thermostat listing says it learns your schedule and the temperatures you like and programs itself, and the Honeywell Home T6 listing describes geofencing that uses your phone location to detect when you are home or away.
Do smart thermostats actually save money?
They can, mainly by not heating or cooling an empty home. The ecobee Essential listing claims savings of up to 23 percent a year on heating and cooling, and the Nest Learning Thermostat listing describes an Eco Temperature when you leave. Both are maker claims, so real savings depend on your home, climate and habits.
Are there any downsides to smart thermostats?
Yes. Their smart features need an internet connection, and many need extra wiring such as a C wire. In Australia the bigger issue is compatibility, because many inverter and ducted systems use proprietary controls rather than standard 24 volt thermostat wiring, so conventional US market thermostats may not work without a compatible interface.
How do I choose a thermostat?
Start with the system you already have, because that decides what will work. Ducted reverse cycle and gas central systems, wall mounted split systems with an infrared remote, hydronic or underfloor heating and plug in heaters each need a different type of device. Then check wiring, the smart home apps you use, and who installs it.
What is the difference between a thermostat and a temperature controller?
A thermostat switches a heating or cooling system on and off to hold a set temperature. A temperature controller does the same job for whatever is plugged into it. The Inkbird ITC-308 WiFi is a plug in temperature controller with a dual relay output for a heating and a cooling device, so it suits a portable heater or cooler.
Can I still buy a Nest thermostat in Australia?
On 16 October 2026 the Google Nest Thermostat showed Currently unavailable on Amazon AU, and Amazon did not know when or if it would return. The Nest Learning Thermostat (3rd Gen) was available there on 16 October 2026, sold and shipped by Amazon US through the Global Store, which warns that US imports may differ from local products.
Is the Nest thermostat being discontinued?
We could not confirm that, because we saved no statement from Google about discontinuation. What we recorded on 16 October 2026: the Google Nest Thermostat on Amazon AU said Currently unavailable and that Amazon did not know when or if it would return, while the Nest Learning Thermostat (3rd Gen) was still listed.
Is a smart thermostat worth it in Australia?
It is worth it when it fits your system and you will use the schedule or away mode. It is not worth it if your heating cannot take one, so check appliance compatibility and local support first. Maker savings claims, such as the ecobee listing's up to 23 percent, are not guaranteed.
Where can you buy a smart thermostat online in Australia?
On 16 October 2026 we looked at seven thermostat products on Amazon AU: the Inkbird ITC-308 WiFi shipped from Amazon and was sold by inkbirdau, four were Global Store imports from Germany, the UK or the US, and two showed Currently unavailable. Google results for thermostats also point to Reece and RS Australia.
What about split system controllers and the brands we left off?
Sensibo, ecobee Premium, AirTouch 5, Daikin Airbase and Milieu Climate appear in the search answers we saved but are not product cards here, because we saved no Amazon AU listing for them or, in Sensibo's case, the listing is an air conditioner controller rather than a thermostat. Each is explained below so you can shop with clear eyes.
Smart AC controllers (Sensibo). If you have a split system air conditioner that uses an infrared remote, this is the category to look at, not a wall thermostat. The Sensibo Air listing says it works with virtually all ACs and heat pumps that use an infrared remote, offers app control with schedules and timers and geofencing, and works with Google Assistant, Amazon Alexa and Apple HomeKit. It requires a 2.4GHz WiFi network. The listing shows 4.3 stars from 1,301 ratings, shipped by Amazon and sold by Sensibo, Inc. We have not made it a product card because it controls an air conditioner rather than acting as a thermostat.
ecobee Smart Thermostat Premium. A search assistant answer we saved names the ecobee Smart Thermostat Premium as a premium option with remote room sensing, voice assistant functionality and air quality monitoring, and says Australian availability and HVAC compatibility should be confirmed before purchase. We saved no Amazon AU listing for it, so we do not review it here.
Ducted and Australian focused controllers (AirTouch 5, Daikin Airbase, Milieu Climate). A search assistant answer we saved names AirTouch 5 for ducted reverse cycle systems with multiple zones, Daikin Airbase for compatible Daikin ducted units, and Milieu Climate for Australian focused controls, described as designed for Australian heating and cooling applications and supporting compatible 24 VAC systems and certain reverse cycle systems with the appropriate adapter. We did not save Amazon AU listings for them, so they are not product cards. Confirm the exact model compatibility with the maker before buying.
The theme across all of these: the right smart thermostat for you is dictated by your system, not by brand. Sort by what is on your wall, then by budget.
What are the alternatives to a Nest thermostat in Australia?
If you want an alternative to a Nest thermostat, the options on this page are the Meross MTS200 for boilers and water based underfloor heating and the Honeywell Home T6 with a boiler receiver box, both Global Store imports from Germany on 16 October 2026. The ecobee Essential could not be bought on 16 October 2026.
A smart thermostat is one piece of a comfortable, connected home. These NestPath guides pair naturally with it and use the same Australian first approach.
