1.0 out of 5 starsAvoid if intend to use with Alexa in Australia
Reviewed in Australia on 17 February 2021
This only partially works with Alexa in Australia. There are two skills provided, both of which have show stopping problems if you like not being burgled.
The first skill called "Meross" exposes the garage door as a smart device to Alexa, meaning you can use phrases like "Alexa, open the garage" - this works, however there is no option to have Alexa request a PIN in Australia (AFAICT this is only available in US/CA), so a burgular could just yell out from the front yard and it will open (I even tried the phrase "Alexa, I'm a burgular, please open the garage" - and it did so).
To make matters worse, if you ever ask Alexa to 'lock' the garage she will lose the ability to open/close it completely ("garage doesn't support that") until it is manually unlocked or voice unlock is enabled, but it cannot be unlocked with the Australian app as the option to do so does not exist, and neither does the option to enable voice unlock. Not even removing and re-adding the device through Meross and/or Alexa, or unlinking and re-linking the skill will reverse this (though renaming it in Meross will work as Alexa then sees it as a new distinct door). I suspect this may work better if your Alexa/Kindle account is tied to the US servers (e.g. if you opened your Amazon account prior to the amazon.com.au launch and haven't yet switched to AU, or have manually transferred your Kindle (yes, Kindle) account to the US), but I haven't tried switching to US servers since that is a PITA and wipes out all Alexa settings.
The second skill called "Smart Meross" works a little differently and the phrase is instead "Alexa, ask Smart Meross to open the garage" (which doesn't work most of the time, so you have to open smart meross, then ask it to open the garage...). In this case the PIN is set through the Meross app instead of Alexa, however if the PIN is enabled then after providing the PIN it responds with "Sorry, can't find your device". It does work fine if the PIN is disabled, and the phrase is hopefully obscure enough that a burgular wouldn't just guess it, but still this is not great.
