      It should be certified very shortly. We will put up another post to let you know when the certification is official.

  • It says the voucher code has already been used?

    • Hi,

      Really sorry about that - there was a mistake on our backend. This should be fixed for you now.

      Any issues, please let me know.

      Kind regards,

  • The Shelly H&T is a great device but I paid $43.48 to have it shipped direct from their website (EUR $26.49).

    Maybe it’s worth paying an extra $20 to get it quicker but I wouldn’t call this a bargain

    • +2 votes


      Definitely agree that direct from Shelly ( is cheaper for the H&T. We buy direct from Shelly in bulk and our current price with 10% discount is the sharpest we can offer with free delivery.

      What the higher price does get you though is:

      • Quicker delivery with often same day dispatch
      • We will manage the warranty for you - any faults covered under the Shelly warranty and we will send you a new item from Sydney. This means less wait time for you and less hassle dealing with Bulgarian time zones.
      • We are always available for support questions and queries and respond the same day.

      Hope this helps explain the difference in price.

      Kind regards,

  • Am I the only one who cant see any value with this yet? I dont own anything "smart" for the house. Any use case for this at all?

    • +2 votes


      Thank you for your questions. I have listed a few use cases for you below:

      • Control your lights from your phone without having to get up
      • Get notified when lights have been left on - you will be able to turn them off remotely from anywhere in the world
      • If you are on holiday, you can set your lights to automatically turn on and off to make potential burglars think you are at home
      • Get your lights to automatically turn on when the sun sets every day
      • The door window sensor can notify you if someone enters your home while you are away
      • These devices have power monitoring, so you can try to save energy in the home
      • The Shelly 1 (blue relay) can by itself, be used to open and close your garage door remotely over WiFi. WiFi is much more secure than the 433mhz frequency that most garage door openers use. I am starting to hear stories of people randomly trying remotes purchased from ebay and successfully opening garage doors.
      • Basically, anything with an on/off switch can be automated!

      The Shelly devices are a just a relatively cheap way to get into home automation. These are just a few use cases, there are hundreds more. But I definitely get your point. Smart homes are not for everyone, but others (me included) love tinkering with this tech and creating new automations. It is a bit of a hobby for us :P

      Any questions about the above, please let me know.

  • Could you add to the description what the products are?

    Shelly H&T


    Shelly Door/Window Sensor


    • Hey,

      I have added descriptions. For full detail, the links to the product pages are also there.

      I welcome any questions that you might have.

      Kind regards,

  • Hi Starburst: these modules look great. Equivalent Fibaro modules are more than double the price. Buying locally is the way to go. Buying overseas stock may not guarantee the Australian certification said to apply to these…not sure. Not affiliated also.

  • The humidity detector with a year battery life is excellent also: use this to turn fans on and off where humidity is a problem.

    • Xiaomi temperature and humidity sensors are no more than $15 delivered with 2yr battery

      • +3 votes


        Yes, Xiaomi temperature sensors are fantastic. They use Zigbee so are very low powered and have long lasting cell batteries which are also cheap. They can also piggy back on an existing Zigbee mesh.

        However, as they are Zigbee based, a hub of some sort is required which costs some more on top of the $15 for the sensor. Zigbee also doesn't have as much range as the WiFi devices unless there is a strong mesh of many Zigbee devices in place already.

        So it is a balancing act in my opinion - if you only want one standalone temperature sensor, Shelly is always the way to go. But if you are looking to implement an entire home automation system with many zigbee devices (must be some powered by mains to create a good mesh), then cheap Xiaomi and Sonoff zigbee sensors always win.

        Hope the further info is useful to all on the thread.

  • Anyone have thoughts/experience on what a sparky would charge to install the Shelly 1 relay? Looking at automating my garage door.

    • Hey,

      A garage door is pretty easy to do - it should take a decent sparky who knows what they are doing no more than 30 minutes.

      Typical rates for electricians are about 60 -90 AUD an hour, so you would be looking at around that price.

      If you would like us to talk to your electrician to explain how to install beforehand, we would be more than happy to assist.

      Kind regards,
      Smart Guys

    • Use the Meross device instead. About $50 delivered, no sparky required as no messing around with Mains. USB powered.

      • It doesn't have anything to do with being USB powered but the fact that you are switching 240 most of the time. It's another story if you're using dry contacts on the garage door and can use low voltage to send the open/close signals though.

  • Yes a garage door is easy: three pin lead to power the unit (active, neutral and earth pin to the cabinet) and then two wires to the relay switch terminals and then onto the external switch terminal on the garage door activator. Very easy ( Garage doors have a remote and often a wired switch for fixing to the wall to open and close the garage door remotely).

  • Do these need neutral wiring?

    • Hi,

      Confirming oraserat's message that these devices require a neutral at the switch.

      If a neutral is not available, you have two options. The Shelly dimmer will soon be certified for use in Australia and does not require a neutral.

      Shelly also recently released the Shelly 1l which is a switch that doesn't need neutral. But it could be quite a while till this is certified in Australia.

  • active and neutral: they switch 240 VAC

  • Does this work with google home?

    • +1 vote


      Yes definitely works with Google home. There is an official integration in the Google home app and set up takes around 2-5 mins once you have a created a Shelly cloud account (free of charge).

  • Here is my installation of the Shelly 1 One

    I was disappointed when Amazon stopped listing them as they were quite competitive in price.

    The system works with google home with API connections, so you can use google home to issue commands like "Turn on bedroom light" etc etc

    As it's technically a "permanent" installation it should be installed by an electrician, but if you're competent it's not a difficult task at all. Typical electricians would just use BP with twists in the cable, i prefer the ferrule and terminal joint method (as pictured)

    It's reliable, never dropped out or had any faults and you can of course control it all remotely. Only installed in bedrooms with partners as the most annoying thing is they get into bed and then noone wants to get up to switch off the light. Other rooms you're probably already up so happy to walk over to turn on/off by yourself :)

    EDIT: also technically the whole mass needs to be installed in an "enclosure" but as the light is a very low power draw, didn't bother
    for the DIYers and even with a hired electrician, note the location of the bridge for various voltages as having it in the wrong place will definitely let out magic smoke (not first hand experience)
