Sadly the lock doesn’t works as it advertised on their website. (matter version) Bought one to only realise that it hasn’t got any functions besides unlock and lock. No way to control the home lock or privacy lock. Nor through ha or Google home. Haven’t got any answer from them when or with what eco system works. So I guess it is a device not ready for the market.
The firmware on my lock is also version prerelease. Bought the device directly from their website.
I have one for testing here, and yes, that function is not implemented by the thread border router from Google or Alexa, the functions are there, and the thread border router implementers are working on showing it. It is not something that SecuYou can fix.
