Bluetooth integration with HA (though ethernet/wifi)

Hi,

I want to get 4 front door locks to integrate with HA but it seems that there are not a lot of options in EU for z-wave.
So I was thinking to get bluetooth locks and use a wifi gateway - maybe with mqtt, such as dusun?

Is there anyway to ensure the compatibility with HA before buying any of them, what would you recommend?

Thanks,
John
