  • How do you integrate this to Australian product/homes?

    • +1

      It's a thermostat that may be able to replace the one you have on your wall, to provide smarter control of the temp in your home. Using sensors it'll keep your home warm when you're in it, and turn the heating off when you're not. You can also remotely control it with your smartphone or via home automation.

      To check if it'll work with your heating unit follow the steps here: http://nest.com/works

    Wow! How does this little thingy cools or heats my room? It just seems impossible. Technology!

    • This thing will only control your aircond or heater (when you set this thing to certain temperature, this thing can turn on/off your aircond/heater). Also can control any other compatible devices such as lights.

      • Is it compatible with remote controlled reverse cycle air con? I watched the video but it seems only covers the wall mounted controllers.

        • Only if your unit already has a wired remote…so unlikely.

        You mean it will control my device that already has a thermostat? Genius! What a great device! They serve advertising as well, just pure genius!

          Your ignorance is showing through, why don't you take a few moments to understand what it does before you confirm people's thoughts.

    Thanks O O!

    Unfortunately this is incompatible with most Aussie reverse cycle air-cons. You'll find most units here use propriety protocols between the wall mounted controller and the unit. In the US they use 24v circuits to control the temperature so it's easy to retrofit the Nest.

    You can check by opening your wall panel and looking at the wires. It'll need to resemble this for you to have any chance.

  • I have ducted actron air, will this work?

    That's some expensive landfill there.

    • Maybe, but that can apply to pretty much every deal posted on this website!

    I have a old Brivis Buffalo Gas heater (from 1980) and use the NETATMO thermostat to make it WIFI controlled. I only had a basic thermostat (off or set temperature) with no timers any functionality.
    Now my heating is contolled from my ipad/iphone and even voice controlled via Amazon Echo.

    The NEST did unfortunatley not work with my model but the Netatmo was super easy to install. I loved the look of the Ecobee but it also did not fit … (it could monitor the temperatures in different rooms).

    These smart thermostats are definitely a nice upgrade when you have an old heater. But make sure they work together …

    • Great tips, i think I have the same buffalo heater, could you please link me to the product you bought? Remote turn on of the heater would be super awesome.

        I am no expert but there will be lots of different Brivis Buffalos. So make sure you check what works. (You need to remove the wall controller and see what cables you have.)

        The new version is Homekit compatible. It was the only smart thermostat I found which was working out of the box with my old heater (and the two cables it has) - pretty much just a switch.

        It has a few drawbacks. You are depended on the Netatmo server (I did not experience any outage in the last 2 years and it reacts within 3-5 sec after I switch it on my ipad). The user interface on the device itself is super minimalistic (only an up and down function) - much more in the app (to set the timers and control it off site). (The Nest or ecobee are a bit fancier).

        I still need to close/open the ducted vents to zone different rooms (will need to find a solution such as a smart vent or zoning for it … but it's out of budget and it might make more sense to replace the heater to a more energy efficient one. (But it feels like this old Brivis is indestructible).

      If you have a newer Brivis with the "networker" controller, you can buy a 529 interface to give your system HVAC (NEST) compatible connectivity.

      We've been using a Nest since their release and it's been flawless.

      • How did you go about finding someone to install this?

      • +1

        Yep … I guess there will be always a way to get something working. But I would leave it to the experts to do this. I looked at the manuals of Nest and ecobee and it was just too difficult for me.

        For my self-install it was easier to go with the Netatmo as I did not need to mess around with cables. My controller was vintage (and looked similar to this one: https://i.ebayimg.com/00/s/OTAwWDE2MDA=/z/qEgAAOSwdzVXpDrO/$_35.JPG ). It was as simple as reconnecting the 2 cables to the new thermostat … it just acts as a switch on/off.

        I got the Netatmo for $170 delivered on ebay so it was a nice cheap upgrade as I could install it myself.
        I guess it always comes down to budget and knowledge (or budget for installer).

        Did you have any troubles with the timezone … I read somewhere that the Nest did not work in Australia as you couldn't set it to the correct timezone. But that was 2 years ago and they might have fixed that.

        • Thanks for the information.
          What are/were the 2 cables you had, if you dont mind sharing. Want to see if they are the 2 I have going into my thermostat (sorry, I have no idea about this stuff!).

        • +1

          @spongetom:

          Sorry … no idea anymore. (was around 2 years ago when I installed it). I suggest to get some help when you are not confident with this … (hehe … I did it in summer so that I have some time to fix things in case I break it).

    Looks cool. And interesting that something designed for a single function (smart thermostat) has also grown to be a home automation controller.

    Can't believe Google paid 3.2 Billion dollars for Nest though. It's classified as one of their "other bets" which typically lose money.

  • +1

    As an alternative you can also look at the ecobee products - the central unit is a bit more expensive however nest requires you to buy additional units if you want more sensors in your home, the ecobee solution has cheaper remote sensors you can spread out your home. These broadly have the same wiring limitations as nest. To retrofit to Aussie 2 wire heating systems you will typically need a 24v power supply and a relay to establish a 'common' power wire.

    • Plus "Ecobee" sounds like an environmentally responsible Transformer (or honey-maker)

    • I've had a nest at home since the first generation and it's been flawless. When we had our first kid i "upgraded" to an ecobee so we could keep the temp in his room consistent overnight in winter.

      It was terrible. The ecobee's thermostat was always way off and causing our house to be way too hot or way too cold. I performed days of testing with the Nest, ecobee, digital thermometer and remote sensor all mounted on the 1 wall to monitor the difference over time.

      The nest and digital thermometer were always within .5 of a degree of each other. The ecobee was off by 2 degrees the majority of the time but not always in the same direction so I couldn't just use their inbuilt offset function.

      Needless to say, i got rid of it and returned to the nest to never have a problem since. Just thought i'd share :)
