General description.

For security reasons, the "Open" (US/CA users)or “Unlock” (DE/IT/ES/FR/UK users) function is disabled by default. You can enable it in the Alexa app device settings.

Method of enabling this option.

Please follow the below figure shows. (This function only available for Meross skill.) 

For US/CA users

For EU users

Regarding the “Unlock by voice” function, Alexa requires the user to set a 4 digits code. Alexa will verify this code each time when you try to unlock the garage door. If you enter the code mistakenly three time in a row, the “Unlock” function will be disabled again.

NOTE:  Alexa has a limitation of the 'unlock' function for some countries, like ES/IT/FR/UK. If you don't have a page as below, you should use the 'smart meross' skill to open the garage by voice. e.g. 'Alexa, ask smart meross to open the garage door'.

If the above points do not help, please email your Meross account to support@meross.com, we will help solve the issue timely.
